Step-down Constant Voltage Constant Current Power Module

Specifications

Output voltage and current adjustment
1. Adjust the CV potentiometer and set the output voltage to the voltage value you need according to your load requirements.
2. Set the CC potentiometer about 30 turns counterclockwise
This action sets the output current to the minimum, connects the load, and adjusts the CC potentiometer to the current you need. For battery charging, after discharging the
battery, Then connect it to the output and adjust the CC to the current you need.
When using it for charging, you must use a discharged battery to adjust it accurately, because the more power the battery has left, the smaller
the charging current it will draw.
Note these fine-tunings must be done with the appropriate voltage or current meter connected.

Description

Product name: 20A high-power synchronous rectification step-down constant voltage and constant current power supply module
Module properties:
Synchronous rectification non-isolated step-down constant current and constant voltage module CC/CV charging module
Scope of application:
High-power LED constant current drive, lithium battery charging (including ferroelectric), 4V, 6V, 12V, 14V, 24V
battery charging, nickel-cadmium nickel-hydrogen battery (battery pack) charging, solar panels, wind turbines
Input voltage: 6-40VDC
The output voltage:
Output current:
Continuously adjustable (1.2-35VDC) If the system will run for a long time, keep the voltage below 32v. This is suitable for applications where the input voltage is higher than the
output voltage and cannot be boosted
Maximum 20A, 15A for a long time (please add a fan to dissipate the power tube temperature if it exceeds 65 degrees, and
use derating for high voltage output)
Current limiting
range: 0.2-20A (adjustable) If the module exceeds 65 degrees, please add a fan
Minimum voltage difference: 3V
Working frequency: 150KHZ
Conversion efficiency: up to about 96%. The efficiency is related to the pressure difference and the use environment.
Output ripple: Ripple is about 50mV (please pay attention to the temperature of the power tube in actual use. If the temperature is too high, please strengthen
heat dissipation or derate the use)
Working temperature: -10? to +75?) (Please pay attention to the temperature of the power tube in actual use. If the temperature is too high, please
strengthen heat dissipation or derate it)
Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease)
Output short-circuit protection: Yes (instantaneous protection) constant current (currently set constant current value cannot be short-circuited for a long time)
Module size: 60*53*27MM (length*width*height)
product weight: About 86g
