It is possible to get changeable output voltage ranges between 1.2V and 36V using the 300W 20A DC-DC Step-down Adjustable Constant Current Module. The module has several current output ranges up to 20 A. It is easy possible to operate high power applications continuously with the heat sink fitted (provided that for continuous high power output you need to use a cooling fan on the heat sink).The Module is created with a specialized benchmark IC and a high-precision current sensing resistor, providing in a more stable constant current (when the constant current is 1A from 20C to 100C, temperature drift is less than 1%), made it extremely well suited for LED driver applications. The module’s output current may be increased to 20A. (for continuous use it is recommended up to 15A with an additional cooling fan).
Features:
- LED driver with high power.
- Charge from a lithium battery (or a lead accumulator).
- power source installed on a vehicle.
- system power supply with low voltage.
- Battery charges at 6V, 12V, 14V, and 24V.
- laptop power supply built-in.
- provision of controlled electricity.
- system for low-voltage power delivery.
Specifications:
