Descripción
Step-down DC-DC constant voltage constant current power supply module with liquid crystal, showing input and output voltage, output current and output power; transparent acrylic board shell is beautiful and elegant, suitable for office power supply, high power LED constant current drive, lithium battery battery charging, etc. . Wear display applications.
Parameter:Input voltage: 5.3-32V (limit 35V; minimum input 4V to achieve step-down, but the input voltage below 5.3V is not accurate)
Output voltage: 1.2-32V (The input voltage must be higher than the output voltage, the minimum differential voltage is 0.8V)
Output current: can work stably at 8A for a long time, and can reach 12A under enhanced heat dissipation
Output power: natural heat dissipation 120W (within 8A), enhanced heat dissipation 160W
Voltage display: resolution 0.05V, range 0-32V
Current display: resolution 0.01A, range 0-12A
Conversion efficiency: about 96%
Working current: about 25mA
Input reverse connection protection: Yes
Output anti-backflow: None (If charging the battery, first power on the module and then connect the battery, and ensure that the battery voltage is lower than the output voltage; after charging, first pull the battery and then power off the module. If there are conditions, please connect the output positively. Current anti-backflow diode
Short circuit protection: Yes
Soft start: Yes (large power with load module may fail when starting)
Size: length * width * height 82 * 52 * 32mm
CC sets the potentiometer for the current, and rotates clockwise to increase the set current. When the load current reaches the set current, it enters the constant current state, the CC constant current indicator (red) lights up; the right CV is the voltage setting potentiometer , rotate clockwise to increase the output voltage. The OUT indicator is an output status indicator that lights up when there is voltage at the output, otherwise it is off.
