- 300W DC buck converter power module input voltage: DC6-40V; Output voltage: continuously adjustable (1.2-35VDC) for a long time 32V or less (for applications where the input voltage is higher than the output voltage can not be boosted)
- Buck converter output current: maximum 20A long time within 15A (power tube temperature over 65 degrees, please add a fan to dissipate heat, high voltage output, please use a derating); Current limit range: 0.2-20A (adjustment) module over 65 degrees, please add a fan
- Minimum voltage difference: 3V; Operating frequency: 150KHZ; Conversion efficiency: up to about 96% efficiency is related to the differential pressure and use of the environment; Output ripple: ripple about 50mV (excluding noise) 20M bandwidth (for reference only) input 24V measured
- The buck module potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease) Output short-circuit protection: there is (instantaneous protection) constant current (the current setting constant current value can not be a long time short circuit)
- Application: Motors, audio, monitor, LED car display, air conditioner, fans, solar energy, photovoltaic energy, DVD, LED lights, pumps, industrial equipment appliances, etc.

output anti-reverse current: no, for load self-charged or inductive load requires additional 2 transistors
Wiring method: terminal block
Output current adjustment method:
1. Adjust the CV potentiometer, according to your load requirements, set the output voltage to the voltage value you need.
2. counterclockwise set CC potentiometer about 30 turns, (that is, the output current is set to the minimum), connected to the LED, adjust the CC potentiometer to your desired current. For battery charging, after the battery is discharged, and then connected to the output, adjust CC to your desired current, (for charging must be used to discharge the battery to adjust only accurate, because the more power left in the battery, the smaller the charging current.)
Wiring instructions:
OUT+: output positive
OUT-: output negative
+IN: input positive
-IN: input negative
CV: output voltage adjustment
CC: output current regulation
EN: enable, low level to turn off the output; pause, high voltage level active
When the input and output ground, no-load CV output constant voltage, CC output constant current
Package included:
4 x 300W 20A buck converter step-down module
