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 3V 5V 6V 9V 12V devices. The voltage precision is 0.1V. Note——The maximum current is 17A. And the actual current is depended on the load. No matter how many voltage is adjusted, the maximum current is 17A and can not be regulated. It can be used to device of 3A 5A 6A 10A 15A 17A. Make sure to use the devices which is below 17A.
【Hareware】 This Buck Converter is equipped with LED screen, heat sink and cooling fan. The LED screen can clearly display output voltage.
【Easy Operation】 After connecting wire, it can be used to adjust output, which is convenient. The potentiometer is pluged into the supply. Only to rotate the potentiometer can adjust output parameter.
【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 input voltage to 110V/220V according to your city voltage.
【Wide Application】 This power supply has variable application. It can be used as a 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 17A. The actual current is determined by load.
Any devices below 17A current can use this product. Any devices above 17A 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 of the item.
If use 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 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.
