DC Voltage Regulator Safety Manual
1. The load connected to the output of the power regulator should not be higher than the maximum load power, any higher load will cause damage to the power regulator.
2. If the ambient temperature is too high, the power should be reduced accordingly. Low temperature operation guarantees that the power supply will work reliably for a long time.
3. Do not use the device near heat sources such as fire or heaters.
4. Do not connect the input cable to the 220V household network. 5.
5. Do not place the device near fire or heaters.
6. The device must not be disassembled and maintained by amateurs.
7. The input voltage should not exceed the fluctuation range of the converter. 8.
8. The output power of the converter must be greater than the power required by the connected devices.
9. Positive and negative lines must not be interchanged.
Package includes:
1 x 20V-60V to 12V 3A 36W step-down converter.
✔12V DC buck converter: input voltage: DC 20-60V; output voltage: DC 12V (fixed output); output current: 3A; output power: 36W. Note: the load connected to the output of the converter should not exceed the specified maximum load. Any major load will damage the buck converter.
✔Easy installation: the 12 V voltage regulator is equipped with a lever nut connection for quick connection. No wiring is required, which reduces wiring time. Note: insulate the wires approx. 10 mm and plug the wires into the connectors.
✔Fuse protection: the step-down converter is equipped with a fuse that provides overcurrent/short circuit/overheating/reverse polarity protection. In case of a problem, the fuse burns through and stops operation, so that the device cannot get on fire. But please note that the positive and negative poles of the product should not be interchanged, which will cause great damage to the product and even a permanent interruption of operation.
✔Waterproof protection: IP67 waterproof transformer adopts non-insulated synchronous step-down technology, working temperature: -20°-65° with ambient temperature change. The transformer is shaped, dustproof, waterproof and shockproof.
✔Wide application: it can be widely used in car audio, surveillance system, advertising screen, medical equipment, instrumentation, electric fan and DIY, etc.
