fAQ
Q: Can this 12V 2.5A (36W rated) power supply operate at full load 24/7?
A: Yes, it can support continuous 24/7 operation, provided there is good ventilation and the ambient temperature is ≤40°C. If it is to be used inside a sealed enclosure, it is recommended to derate the load to prevent heat accumulation.
Q: Why is the voltage at the device end lower than expected when using a long output cable? How can this be resolved?
A: At a current of 2.5A, the resistance of a long cable causes a voltage drop. Solutions include using a cable with a larger wire gauge, or coordinating with the factory to slightly adjust (increase) the output voltage to compensate for line losses.
Q: What causes the power supply to shut down automatically and then resume operation after cooling down?
A: This is most likely due to the activation of Over-Temperature Protection (OTP). Common causes include poor ventilation, high ambient temperature, or the adapter being covered or obstructed. Improving the cooling environment usually resolves this issue.
Q: How should I troubleshoot if the power supply repeatedly turns on and off (hiccup mode) as soon as a load is connected?
A: ① Check if the peak power required by the device during startup exceeds 36W; ② Check for any hidden short circuits in the wiring; ③ Determine if the load has a high inrush current; if the inrush current is excessive, consider adjusting the over-current protection threshold.
Q: Is it normal for the casing to feel warm?
A: Yes, it is normal. A 36W adapter will generate some heat when operating at full load, so a slightly warm casing is expected. However, if it feels noticeably hot to the touch, you should check the ambient temperature and ventilation conditions.
Q: What input voltages are supported? Can it be used in different countries?
A: It features a wide-input voltage range of AC 100–240V (50/60Hz). It is designed for global use; you simply need to use the appropriate AC power cord for the specific country (e.g., EU, US, or UK standard) to fit local wall outlets.
Q: What built-in protection features are included?
A: Standard features include OCP (Over-Current Protection), OVP (Over-Voltage Protection), SCP (Short-Circuit Protection), and OTP (Over-Temperature Protection). In most cases, the unit will automatically recover once the fault is cleared. We also offer customizable "latching" (non-auto-recovering) protection schemes.
Q: Will the power supply be damaged if the DC connector's polarity is reversed?
A: The standard version does not include built-in reverse-polarity protection. Reversing the polarity can easily damage the connected device and potentially the power supply itself. If there is a risk of incorrect connection in your application, we can add a custom reverse-polarity protection circuit.
Q: How is the ripple performance? Is it suitable for powering precision equipment?
A: The unit features a multi-stage filtering circuit, keeping ripple within an acceptable range. For precision equipment that is highly sensitive to noise, we can enhance the filtering design to further reduce ripple interference.
Q: Can the specifications be customized?
A: Within the 36W power platform, we can customize the current (downward) and adjust the output voltage, provided the total power does not exceed 36W. We also offer customization for DC connector types, cable lengths, and custom logo printing on the enclosure.
Q: What tests are performed before the units leave the factory?
A: Finished products undergo full-load burn-in testing, as well as electrical testing-including withstand voltage, leakage current, output voltage, and protection threshold verification-to screen out any early-stage defects.
Q: What are the typical application scenarios?
A: It is suitable for powering 12V devices (up to 36W), such as LED strips, small security cameras, compact industrial control equipment, smart home devices, and small-scale commercial terminals.
Q. How to package the product before transportation?
A:Each product is packaged in a white box or PE bag. The color box needs to be customized and then packed into a large carton. Depending on the size of the product and the size of the carton, it can package 50 pieces/carton, 100 pieces/carton, 150 pieces/carton, 200 pieces/carton, and so on.
Q.How long is the lead time?
A.If there is inventory, ship on the same day;
Out of stock, shipped within 15 days;
Urgent delivery within 7 days.
Q.Where is the factory located?
A.In Baoan District, Shenzhen,China
Q.How long is the warranty and how is it guaranteed?
A.Certified products with a 3-year warranty;
Non standard products with a one-year warranty
Q.Can you send free samples?Is the shipping fee also free?
A.I can send free samples, but the delivery cost will be paid by yourself.
Q.do you make other power supplies?
A.We produce power adapter, switching power supply, wall plug power supply, desktop power supply, aluminum case power supply, power box, ultra-thin black aluminum case, ultra-thin white aluminum case, bare board power supply, power module, battery charger, USB charger, type-C charger, outdoor power supply, emergency start power supply, UPS power supply, CCTv power supply, LED power supply...
