About DC -DC 4A DC 5.5-30V To DC 0.5-30V 0.3-3A Automatic
Output ripple is small, LC filter; with heat sink, send module support isolation column. Module parameters: 4A non-isolated buck constant current power supply module Input voltage: 5.5-30VDC (input voltage 5V, but also can achieve buck, but the voltage and current measurements are not accurate; less than 4.7V, undervoltage protection) Output voltage: 0.5-30VDC adjustable Output current: 0.2-3A adjustable, enhanced cooling up to 4A (the module temperature exceeds 65 degrees or the use of power more than 35W, please strengthen the heat) with constant current indicator Voltage display resolution: 0.05V Current display resolution: 0.005A Conversion efficiency: about 88% Soft start: Yes (very powerful with load module may fail to start) Input reverse protection: Yes Output anti-intrusion: Yes Short circuit protection: yes Working frequency: 180KHZ Size: L * W * H 66 * 48 * 21mm Mounting hole: 4mm in diameter Weight: 46g Instructions: 1. The module has IN / OUT, ON / OFF two buttons: IN / OUT button to switch the input voltage and output voltage display, long press to switch the output current output power display; ON / OFF button control output ON or OFF, long press Set the power-on default output state is ON or OFF the next time. 2.CC set potentiometer for current, turn clockwise to increase set current, when the load current reaches the set current, enter constant current state, CC constant current indicator (red) lights up; right CV is voltage setting Potentiometer, clockwise rotation, can increase the output voltage.
