Output voltage: 1.25-30V continuously adjustable
Output Current: 10A (MAX) (5A long natural heat inside)
Output current range: 0.2-10A
Working temperature: -40 to + 85 degrees
Operating frequency: 150KHz
Conversion efficiency: Typical 91% (12V turn 12V5A) maximum 93%
Overcurrent protection: there

Output anti-anti-irrigation: Yes, no need for charging plus blocking diode.
Connection: Terminal output, (IN is the input, OUT output)


Output current adjustment method:
1. CV potentiometer adjustment, depending on your load requirements, the output voltage is set to the voltage value you need.
2. CC potentiometer counterclockwise located about 30 laps, (ie, the output current is set to a minimum), connected to the LED, potentiometer CC tune to the desired current. After charging for battery, the battery fully discharged, and then to output, adjust to your desired current CC, (be sure to use for charging batteries completely discharged before being allowed to transfer, because the battery power is left in the more, the charging current is smaller.) Please do not use the short-circuit current way of transfer, the circuit structure of the module can not short-circuit the way transfer

    I used this module to build a variable power supply.
    I use an input voltage of 12 volts (from a computer power supply) and need this module to create a variable (settable via the potmeter) output voltage ca 1 - 30 volt.

    With output voltages over 12 volts everything works fine.

    In the step down mode (voltages below 12 volt) the output voltage is not stable. For instance if I set the output voltage to 5 volts and apply no or very little load, then the outputvoltage "swings" between 4.8 and 5.3 volt.
    This only stops if I apply a larger load that draws at least 500mA of current.

    Great product. I used it to build a bench power supply with 2 variable channels and it works fine.

      Q: Is it OK to connect input minus together with output minus?
      A:
      You don´t have to do this. They are already connected on the board. If you measure the resistance -> It is 0 Ohm !

      Q: Hello, what exactly are the trimmers values? 20kOhms? 200kOhms For voltage regulation and current regulation? Best regards
      A:
      the picture shows 204 for both potis, that means 20 +4 times 0. that means ***** Ohm > 200 KOHM

      Q: What is the power output rating of this device in Watts?
      A:
      I bought 4, tested all four, and was disappointed. Unfortunately, it cannot give the values in the descriptions. Above 2.5 amps voltage drops. it gets pretty hot. It is not possible to run a laptop. Not bad for 25 watts of energy needs.
