YOU NEED TO KNOW :

Please follow the wiring instruction and connect them strictly：

1.The load connected to the output end of the power regulator should not be more than max listed load power；

2.If there are multiple output wire, do not combine the load.

3.Leave a margin for the power supply to ensure long-term stably working.

How to Choose the Correct Current for Loads?

For example, if the max current of your load device is 10A, then choose 10A/0.8=12.5A at least for resistive loads according to international standard. If the load device is motor or compressor, then you may choose 10A/0.5=20A according to real testing result since the motor and compressor starting current may be 2-3 times than nominal current.

Wide Applications

These compact size dc voltage reducer converters are high reliability power transformers. They can work safely and reliability within temperature range -40°C~80°C.

Widely used to golf cart, motor, speaker, GPS, LED car display screen, air-conditioner, electric fan, solar energy, photo-voltaic power, DVD, industrial equipment ect.

If the converter does not work, please check this following steps:

1. Please to check whether the power supply has voltage

2. Whether the terminals are in poor contact and whether the wire ends are connected securely

3. Please to check whether the wires are installed as shown in the pictures and instructions. If the wires are not installed correctly, the voltage regulator will not work

If all the above are correct, please reach out us and we will solve your problem immediately.

PLEASE NOTICE :

1. The input voltage should not exceed the fluctuation range of the converter can withstand.

2. The converter output power must be greater than output nonnection device required power.

3. Positive and negative wires can't be reversed connection.
