• Module name: 12A synchronous rectifier decompression module, constant voltage constant current
• Module property: non - isolating pressure module (BUCK) synchronous rectifier
• Input voltage: 4-32V (limit 35V) please keep the voltage margin.
• Adjustable output voltage: 1.2-32V (default output around 18V, if to the module is powered on, found around rotating potentiometer voltage output voltage is always did not change, you first the voltage potentiometer counterclockwise circle above 15)
• Input output minimum differential pressure: 0.8V
• Output current: 0-12A time natural heat dissipation 8A, temperature not exceeding 60 degrees. Use when the temperature is high.
• Output constant current range: 0-12A
• Working temperature: -40~+85 degrees
• Working frequency: 150KHz
• Conversion efficiency: highest 98% (efficiency is related to input, output voltage, current, differential pressure)
• Short circuit protection: (limited current is current constant current value)
• Input reverse protection: no (if you need to enter a diode in the input string)
• Output anti-retro-protection: no (if you need to put the diode in the output string, please add the anti-diodes between the output of the module and the battery when used for charging application, otherwise it will damage the module.)

The method of setting voltage and current:

1. set the output voltage: according to you want to charge the battery of float charging voltage value, or after leds in series, in parallel, adjust the voltage value of constant pressure potentiometer (CV), the output voltage is set to the required voltage. (without load)
2. Set constant current value: turn the first CC potentiometer into 20 circle-clockwise, and short-circuit output with multimeter 20A current, and adjust the CC potentiometer to the current value that you need to set.

Note: the voltage of constant current setting is higher than 1.2 V, otherwise the constant current function will fail.
