FAQs
1. What is a wide voltage power module?
Wide input voltage range, stable output under voltage fluctuation, ideal for industrial, automotive and battery-powered applications.
2. Difference between wide voltage & normal modules?
Normal modules have narrow input range; wide voltage modules have better adaptability and anti-interference for complex conditions.
3. How to choose input voltage range?
Select with 10%–20% margin. 9–36V for industrial, 18–75V for automotive.
4. Can it work beyond rated voltage?
No. Overvoltage may trigger protection or damage the module. Use within rated range only.
5. Need external input protection?
Fuse, reverse polarity protection, TVS and filter capacitors are recommended for reliability.
6. Low output & poor load capability?
Check input voltage, load, wiring drop and over-temperature derating.
7. How to reduce ripple & noise?
Add output filter, shorten wiring, optimize grounding and reduce inductive interference.
8. Frequent restart & protection?
Usually caused by overload, short circuit, abnormal input or overheating. Test without load first.
9. What protections are built-in?
Under-voltage, over-current, short-circuit, over-temperature protection with auto-recovery.
10. Can be series or parallel connected?
Not recommended without voltage/current sharing, may cause module damage.
11. Notes for high temperature application?
Derate 20%–50% above 70℃, improve heat dissipation to avoid over-temperature protection.
12. What’s the function of isolation voltage?
Improve safety, suppress interference, protect loads and personnel.
