ARCELI Boost Buck Converter,Constant Voltage Current DC- DC Step-Down Communication Power Supply Buck Voltage Converter LCD Voltmeter 50V 20A?DPS3005+USB+BT?

Description: This constant voltage and constant current programmable control power supply module makes analog integration and digital control functions combined in one. Specification: Input voltage: 6-40V Output power: 0-160W Output voltage: 0V-32.00V Output current: 0-5.000A Output voltage resolution: 0.01V Output current resolution: 0.001A Output Voltage accuracy: +/- (0.5% + 1 digit) Output Current accuracy: +/- (0.5% + 2 digits) Note: Input voltage must 1.1 times higher than the output voltage. When large current circumstances, pay attention to heat elimination. Wiring: IN+: Input positive IN-: Input negative OUT+: Output positive OUT-: Output negative Note: The maximum input voltage is 40V. It is better to make the value less than the limit value, otherwise the item maybe be damaged. output for battery charging or capacitive load, please add a diode on output positive in case that the current flow backward the module. Do not use the meter in AC power supply, and wiring should be exactly the same as the wiring diagram, or else it will cause damage. Package Included: 1 X DP50V5A Power Supply Module 1x USB Communication Board 1x Bluetooth Communication Board 1x Cable
