FAQ

 

Q: What is a waterproof power supply?

A: Waterproof power supply is a kind of LED driving power supply. What sets it apart from ordinary LED driving power supplies is its waterproof function. According to different needs, waterproof power supplies can be designed with IP65, IP66, IP67, IP68, and other waterproof and dustproof ratings. Among these, IP68 can be completely immersed in water. IP65, IP66, and IP67 cannot be completely immersed in water but can be briefly submerged, and they can work normally even if the surface is sprayed with water or gets wet. Therefore, a waterproof power supply has more stable performance, a wider application range, and a higher safety factor than ordinary power supplies!

Q: How to choose a waterproof power supply?

A: 1. Select appropriate input voltage specifications; for example, 12V, 24V, or 48V can be customized according to your needs. 
2.Choose the appropriate power. To extend the life of the power supply, you can choose a model with 30% more output power rating. For example, if the device only requires 100W of power, it is best to purchase a waterproof power supply with more than 120W. 
3.Consider the load characteristics. If the load is a motor, light bulb, or capacitive load, the current will be large when the power is turned on, and a suitable power supply should be selected to avoid overload. If the load is a motor, voltage backflow during shutdown should be considered. 
4.Additionally, the working environment temperature of the power supply and whether there is additional auxiliary heat dissipation equipment need to be considered. If the ambient temperature is too high, the power supply needs to derate the output according to the derating curve of ambient temperature to output power. 
5.Select various functions according to the needs of the application: 
Protection functions: over-voltage protection (OVP), over-temperature protection (OTP), over-load protection (OLP), etc. 
Application functions: signal function (normal power supply, power supply failure), remote control function, telemetry function, parallel function, etc. 
Special functions: power factor correction (PFC), uninterruptible power supply (UPS). 
6.Consider the installation space and choose a waterproof power supply of appropriate size based on the actual installation space.

Q: Is LED waterproof power supply a rainproof power supply?

A: Let me simply tell you that LED waterproof power supplies and rainproof power supplies are both outdoor power supplies. However, the waterproof levels of the two are different. Generally speaking, power supplies rated IP63 or above are rainproof and can protect against rain. The IP67-rated power supply is waterproof and can be immersed in water for a short time without being damaged, but the water temperature should not exceed about 45°C. IP68-rated power supplies can be completely immersed in water.

Q: Is LED rainproof power supply really practical?

A: With the development of LED lighting, outdoor usage has become more and more popular. However, the outdoor environment is ever-changing, with increasing occurrences of rain as the seasons change. This has also prompted the development of LED rain-proof power supplies. As we all know, the reason why LED power supplies are accepted by the public is mainly because they are small in size, light in weight, and very convenient to install. Moreover, our company employs a one-time molded aluminum shell structure, which is also a key advantage of LED rainproof power supplies. It is integrated and seamless. 
The cast aluminum process prevents rainwater or steam from penetrating through gaps, making it completely waterproof. The product does not rust, has good heat dissipation, and exhibits low temperature rise. This effectively ensures the waterproof level of the product and greatly extends its service life. 
In addition to the outer shell, the product is also equipped with short-circuit and over-current protection. When the load is abnormal, the product automatically cuts off the output power to prevent the accident from expanding. The product design margin is 110% of the rated value. All products guarantee 100% rated load output.

Q: What are the advantages of LED power supply?

A: As a branch of the power supply category, LED power supplies now occupy a significant position in the power supply market. They boast advantages such as high brightness, low power consumption, long life, fast startup, low power, absence of stroboscopic effects, and reduced likelihood of visual fatigue, making them a preferred choice among consumers

Q: What is the difference between isolation and non-isolation in LED power supply?

A: Differences in Security: An isolated power supply employs a transformer to reduce the 220V voltage to a lower voltage through the transformer, which is then rectified into a DC output for power supply. The primary coil of the transformer withstands the 220V voltage, while the secondary coil only handles the output low AC voltage. Since the primary and secondary coils are not directly connected, it is called an isolated power supply. The conversion process of the transformer involves electricity, magnetism, and electricity. As it is not connected to the earth, there is no risk of electric shock. 
A non-isolated power supply directly inputs 220V into the electronic circuit, which then outputs the voltage through electronic components. The input and output are directly connected through these components, hence the term non-isolated power supply. The main difference between the two lies in the presence or absence of a transformer. LED non-isolated designs are limited to double-insulated products, such as light bulb replacements, where the LED and the entire product are integrated and sealed in non-conductive plastic, eliminating the risk of electrical shock to the end user. Secondary products are all isolated and relatively expensive. In non-isolated circuits, the input power is directly applied to the LED load after being boosted and buckled, posing a risk of electric shock. 
Therefore, it is challenging to obtain safety certifications such as 3C, UL, CE, etc., without isolation. Generally, manufacturers lacking absolute design and technical strength find it difficult to obtain such certifications. Insufficient insulation and creepage distance necessitate designing based on the physical structure of the lamp. Although lamp tubes are acceptable, some are fully plastic. For instance, the insulation between the LED and the aluminum radiator typically relies on the film insulation of the printed circuit board of the aluminum substrate. Although this insulation layer can withstand 2000V high voltage, burrs in the screw holes may produce the so-called creepage phenomenon, making it challenging to pass CE certification. However, for a complete LED lighting product, parts of the product surface that users can touch must be isolated to prevent electric shock. From the perspective of the entire product system, isolation is inevitable, and the only difference lies in where isolation is set. As a product intended for safe use by end users, insulation and isolation reliability must be considered. 
Note: It is worth noting that, in order to save costs, some manufacturers adopt the method of tapping the main coil directly to extract low voltage. Although this method may appear to include a transformer, it lacks a secondary coil and thus cannot be considered an isolated power supply. 
2. Different Electrical Properties: In terms of performance, isolated power supplies offer several advantages: they do not pose a threat to the human body, and their wide voltage range performance is very good. Non-isolated power supplies are also mature now, although their voltage range is slightly narrower compared to isolated ones. Non-isolated power supplies typically operate between 110V and 300V, while isolated power supplies can achieve voltages ranging from 60V to 300V. Both types provide even high and low currents. Isolated drives are safe but have lower efficiency, whereas non-isolated drives are more efficient. The choice between isolated and non-isolated drives should be made based on actual usage requirements. 
In terms of constant current accuracy, isolated types can achieve within ±5%, but non-isolated types may find it difficult to achieve the same level of accuracy. Non-isolated circuits are highly sensitive to surges and have poor suppression capabilities against lightning surges. Lightning surge, characterized by instant high voltage reaching several thousand volts for a very short duration with extremely strong energy, can damage non-isolated BUCK circuits. This voltage may be instantly transmitted to the output, damaging the constant current detection loop or the chip itself, potentially causing the entire lamp to burn out. Consequently, non-isolated power supplies have a higher repair rate when shipped in batches, mostly due to damage. In contrast, the probability of an isolated power supply malfunctioning is much smaller, typically around 2% to 3%. 
Note: Therefore, the inclusion of a non-isolated anti-surge varistor is essential. Without the varistor, the warranty may be rendered ineffective. 
3. Cost and Efficiency: The cost of electronic products encompasses not only design and production expenses but also maintenance costs for large-volume products. Regarding the LED power circuit structure, current isolation solutions mostly employ AC/DC flyback circuit solutions, resulting in relatively complex circuits and higher costs. In contrast, the non-isolated type typically utilizes a DC/DC boost (Boost) or buck (Buck) circuit, leading to simpler circuits and lower costs. Since non-isolation reduces the energy loss of the transformer, efficiency can generally exceed 90%, accompanied by a higher power factor. Isolation, on the other hand, generally achieves an energy efficiency of 88%, depending on the power, resulting in relatively higher heat generation. 
Non-isolated power supplies have advantages over isolated ones in terms of efficiency and cost. Improving the efficiency of isolated power supplies is challenging, as inadequate handling can lead to significant heat generation and increased costs, especially for LED fluorescent lamps with built-in fixtures. However, non-isolated power supplies may experience considerable damage when shipped in large quantities due to their limited ability to suppress lightning surge voltages. 
Compared with isolated power supplies, non-isolated ones primarily reduce the number of transformers, utilize minimal materials in structural design, and achieve the same product functions, resulting in greater cost advantages. This is likely why non-isolated power supplies are highly popular in China. 
Note: Among low-voltage power supply LED lamps, prioritizing efficiency and cost, the non-isolated solution is indeed the optimal choice. 
4. Usage Occasions: Whether to use an isolated insulating transformer or an isolated protective lampshade casing typically requires analysis from various perspectives, including cost, manufacturing process, efficiency, volume, insulation reliability, and safety specification requirements. Both designs will continue to be used as they cater to different market needs.
In terms of load range, an isolated power supply typically offers an output load range of 30-42V, while the non-isolated load range can extend to 30-84V. When selecting a power supply, many LED manufacturers prefer options that can accommodate full voltage input of 90-265V and a load range of up to 84V for overall adaptability. However, such a choice entails certain risks and hidden dangers. At 90V input, the power supply may lose its constant current function and total harmonic distortion (THD). Non-isolation is suitable for high voltage and small current applications, but the cost of large current is not necessarily cheaper than isolation. 
Suitable occasions for non-isolated power supplies include indoor lamps, where the electrical environment is better and there is less susceptibility to surges. However, for applications using straw hats and SMD LEDs in high-voltage, small-current, or low-voltage, large-current scenarios, non-isolation may not be practical. In centralized lighting scenarios, where hundreds of lamps are connected to the same AC line, non-isolated power supplies are often used due to the dirty voltage environment, which increases the risk of lamp damage. From a product system perspective, isolation is inevitable, with the difference lying in where the isolation is set. Some designers opt for an isolated transformer design to simplify heat dissipation and lampshade design, while those using a non-isolated drive design must ensure reliable insulation in structures such as lamp housings.
Note: Isolated and non-isolated solutions have coexisted as power drivers, each with its own advantages. Non-isolated power supplies focus on achieving higher power factor and efficiency, reducing energy loss, while isolated power supplies prioritize life safety and overall lamp usage safety, albeit slightly inferior in power factor and efficiency. There are no strict rules for choosing different power supply types in different occasions and usage environments.
