Description
Parameter
Input voltage: 4-38V
Output power: 75W(Max)
Transfer efficiency: 96%(Max)
Output current: adjustabel;5A(Max)
Output voltage: 1.25-36V constantly adjustable
Input reverse connection protection: NO
Short-circuit protection: YES(limited current of 8A)
Over-temperature protection: YES(item will stop output automatically)
How to set current limits:
1. Adjust constant-voltage potentiometer to make output voltage reach the voltage value which you want.
2. Use 10A multimeter to measure short-circuit output current (directly connect two meters to output interface), at the same time, adjust constant-voltage potentiometer to make output current reach preset over-current protection value. (If the current value multimeter displays is 4A, the maximum current of the module only can be up to 4A; when the current reach 4A, constant-voltage constant-current red indicator light is on, or the light is off)
LED indicator light:
1. Red light is on in constant current status and off in constant voltage status.
2. Blue light is on when charging and off when full-charging
3. Green light is on when full-charged.
Package includes:
1 X Buck Converter
Features
- DROK voltage converter input voltage range is DC 4-38V, output current is adjustable, max output current is 5A, max output power is 75W.
- Multifunctional: it can be used as buck converter module with over-current protection; it can also be used as high-power LED constant current driver module; what's more, it can be used as battery charger (e.g. nickel-cadmium or nickel-metal hydride battery, lithium batteries), can be used in solar panel/wind turbines etc.
- Safe Protection: the buck regulator is designed with short-circuit protection(limit current 8A), over-temperature protection, without input reversed connection protection.
- CC & CV: the volt transformer is with two working modes of constant voltage and constant current, which would be indicated by the red led indicator.
- Note: please kindly note that when buck converter module is used in more than 3A,35W, please strengthen cooling.
