About this item
【Volt Adjustment】 Input Voltage can be 110V or 220V. Wide adjustable output Voltage range: DC 0-12V. This supply is suitable for 2V 3V 5V 6V 9V 12V devices. The voltage precision is 0.1V. Note——The maximum current is 40 A. And the actual current is depended on the load. It can be used to device of 5A 10A 20A 30A 40A . Make sure to use the devices which is below 40A.
【Hareware】 This Buck Converter is equipped with LED screen and cooling fan. The LED screen can clearly display output voltage. When the running power is high, the cooling fan will automatically activate.
【Easy Operation】 After connecting wire, it can be used to adjust output voltage directly with potentiometer.
【Protection】 Over Load Protection, Over Voltage Protection, Short Circuit Protection, which can protect your device from damage. Note: the default input voltage is 220V, before using, please switching the voltage range to match actual input voltage
【Wide Application】 This power supply has variable application. It can be used as 2V 3V 5V 6V 9V 12V power supply for RV, Car, Labtop, Computer, Lab, CCTV, Ham Radio, etc. All of our item has one year long time warranty guarantee.

Instructions for use:
The current is unregulated and maximum is 40A. The actual current is determined by load.
Any devices below 40A current can use this product. Any devices above 40A current cannot use this product.
Before using, please select the input voltage 110V/220V according to your local voltage, to avoid damaging, switch is at right side
For motor, fan and other inductive load, please pay attention to the load’s maximum starting current parameter. This parameter shall not be higher than the power supply’s max output current. Otherwise it may damage the power supply. Otherwise you need to allocate the soft starting protection circuit for the load to absorb the impact current.
