About this item
【Volt Adjustment】 Input Voltage can be 110V or 220V. Wide adjustable output Voltage range: DC 0-48V. This supply is suitable for 5V 9V 12V 24V 30V 36V 48V devices. The voltage precision is 0.1V. Note——The maximum current is 5A. But the actual current is depended on the load. No matter how many voltage is adjusted, the current is 5A and can not be regulated. It can be used to device of 1A 2A 3A 4A 5A. Make sure to use the devices which is below 5A.
【Hareware】 This Buck Converter is equipped with LED screen, cooling fan. The LED screen can clearly display the output voltage. cooling fan can control the temperature in a safe range. During the running power is high, the cooling fan will automatically activate with little noise.
【Easy Operation】 After connecting wire, it can be used to adjust output voltage directly, which is convenient. The potentiometer is inset 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 5V 12V 24V 30V 36V 48V 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 non-adjustabled and maximum is 5A. The actual current is determined by load.
Any devices draw below 5A current can 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 . This parameter shall not be higher than the power supply’s max current. Otherwise it may damage the power supply. Or you need to allocate the soft starting protection circuit for the load to absorb the impact current.
