Description

Parameters:

Modular nature: synchronous rectification non-isolated step-down constant current constant voltage module.

Input voltage: 6-40VDC.

Output voltage: continuously adjustable (1.2-35VDC) for a long time 32V (for the input voltage is higher than the output voltage of the application can not be boost).

Output current: maximum 20A long time 15A (power tube temperature exceeds 65 degrees please add fan cooling, high voltage output please derating use).

Current limit: 0.3.-20A (adjustment) module over 65 degrees Please add a fan.

Minimum differential pressure: 3V

Operating frequency: 150KHZ

Conversion efficiency: up to about 97% efficiency with pressure and use of the environment.

Output ripple: Ripple 50mV (no noise) 20M Bandwidth (for reference only) Input 24V measured.

Working temperature: -10 to +75 ) (the actual use, please pay attention to the power tube temperature, the temperature is too high, please strengthen the use of heat or derating).

Potentiometer adjustment direction: clockwise (increase), counterclockwise (reduced).

Output short circuit protection: Yes (instantaneous protection) Constant current (current set constant current value can not be short time short circuit).

Input Reverse Protection: None, Output anti-anti-flooding: no, for the load from the charged or inductive load need to add a diode.

Wiring method: Terminal block.

Module size: 60 * 53 * 30MM

Applications: High power LED constant current drive, lithium battery charging (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel-cadmium nickel-metal hydride batteries (battery pack) charging, solar panels, wind turbines.

Output current adjustment method:
  •  Adjust the CV potentiometer, according to your load requirements, the output voltage is set to the voltage you need.
  • Counterclockwise set CC potentiometer 30 laps or so, (that is, the output current is set to minimum), connected to the LED, adjust the CC potentiometer to your current. For the battery charge, the battery after the termination of power, then receive the output, adjust the CC to the current you need, (must be used for charging when the battery is fully charged because the battery remaining power More, the smaller the charging current.
