Specifications:
Input voltage: 4.5-32V
Output voltage: 1-30V continuously adjustable
Output constant current range: 0.3-12A (default output constant current is 3A)
Output turning lamp range: 0.1-5A (default turning lamp current is 0.3A) The current range will have a little error due to the difference in part parameters
Operating temperature: -40~+85 degrees
Working frequency: 380KHz
Conversion efficiency: 97% (MAX) (efficiency is related to input, output voltage, current, pressure difference)
Short circuit protection: Yes (limit current to set constant current value)
Overtemperature protection: Yes (automatically turn off output after overtemperature)
Input reverse protection: Yes
Installation method: 4 3mm screws
Wiring mode: Wiring terminal (welding output when configuring the shell) V-IN is the input, and V-OUT is the output
Module size: 70mmx52mmx50mm
Notice:
This power supply has constant voltage constant current short-circuit protection function. The LED can be driven with constant current mode, and the battery can be charged, but the battery is not fully charged when the indicator light is charged.
The current detection of the module is low-end detection, please do not short-wire the input negative electrode and the output negative electrode directly!
If the module is a step-down power supply, it can only be step-down. The input voltage must be higher than the output voltage.
Voltage/current/Overcurrent protection point/Regulation method:
Constant voltage regulation: Rotate the "constant voltage regulation" potentiometer on the power supply board according to your own desired voltage. Turn down the voltage clockwise (turn right). The reverse clock (turning left) voltage rises.
Constant current regulation: Before setting the current, turn the "overcurrent regulation" potential to the left to Z maximum, (default is high. Generally do not need to adjust) Use the multimeter 20A current short-circuit output, adjust the "constant current regulation" potentiometer to the current you need, turn down the forward clock current, turn up the reverse clock current.
Overcurrent regulation: Designed for output short circuit, meaning that when the output short circuit exceeds the set short circuit current, the power supply turns off the output to protect the power module and electrical equipment from damage. Adjustment method: First set the current of the protection point, if it is 5A protection. Use the constant current regulation method to output current to 5A, and then adjust the "overcurrent regulation" potentiometer (clockwise rotation) to the output no current can be. The crossing point of some time is 5A. (Note that if the current of the protection point is lower than the current required by the device, the power supply will be protected. It is recommended to keep the default if overcurrent protection is not required.)
Note:
1.Due to the light and screen difference, the item's color may be slightly different from the pictures.
2.Please allow 1mm-1cm differences due to manual measurement.
