Product description
Voltage and current adjustment method: (the use of tools multimeter, a screwdriver)
Voltage adjustment: according to their own required voltage rotating power board VIADJ blue potentiometer, clockwise voltage up, counterclockwise down
Output current adjustment: multimeter or ammeter to 20A or 10A current gear, the power supply voltage to 5V, constant current potentiometer IADJ counterclockwise about 10 turns, the current is adjusted to the minimum with a multimeter short-circuit output, and then clockwise adjustment of IADJ potentiometer to adjust the current to the required current value, (Note: constant-current potentiometer IADJ counterclockwise turn 10 turns, the power supply may not have an output voltage, this time because the current to 0A. Do not worry about him, clockwise adjust the current will have an output.)
Module current detection for the low-end detection, please do not input the negative pole and the output of the negative pole directly with a short wire, short-circuit negative power supply does not constant current, resulting in damage to the power supply and the need for constant current power equipment.
Module for the buck power supply can only buck not rise. The input voltage must be higher than the output voltage.
The input has no reverse connection protection, positive and negative reverse connection is strictly prohibited.
If charging the battery, the output is connected to the inductive load, the output should be added to prevent the return of the diode.
Long time high power, high current, do a good job of heat dissipation.
Main features of the power module
The module adopts step rectifier program, high efficiency, the highest efficiency of up to 95% * output voltage and current continuously adjustable
Input voltage up to 75 volts, output voltage up to 60V (input 75 volts at a maximum current of 25 amps)
Module name:600w step-down constant voltage constant current adjustable power supply module
Module nature:non-isolated buck module (BUCK)
Output voltage range:2.5-60V (must meet the buck conditions, IN input multiplied by 0.8)
Output minimum voltage:2.5V
Maximum output voltage:about equal to the input voltage * 0.8 (for example, input is 40V, 40V * 0.8 = 32V maximum output voltage is 32V)
Output constant current:1-25A (continuously adjustable)
