• Operating frequency: 180KHz
• Conversion efficiency: up to 96%
• Short circuit protection: Yes
• Input reverse polarity protection: None
• Over-temperature protection: Yes (Automatically shut off the output when over-temperature.)
• Connection: terminals or solder terminals; VIN is input; VOUT is output
• Module dimension: 65.6 x 40 x 25mm

• In the case of power off, press and hold the "SET" key and power on, then enter into voltage calibration mode, and LCD screen starts to flash, release the "SET" key;
• press "SET" and "ENT" key to increase or reduce the voltage to the right input voltage. It will automatically saves after 2s, then power off and the calibration is complete.

• Suitable for no-load with current display or slightly large current. In the case of power off, press and hold "ENT" and power on, then enter into current calibration mode and LCD screen starts to flash, release the "ENT" key; press "SET" and "ENT" key to increase or reduce the voltage to the right value. It will automatically saves after 2s, then power off and the calibration is complete.
