Step UP/Down Converter Boost/Buck DC-DC 5-32V to 1V-30V CC CV Power Supply Module Short Circuit Protection

Output Flow Back Protection: Not support. If  used for storage battery charging or powered inductive load, a schottky diode can be added in series at output. Weight: 45g / 1.6oz (approx.) Note: If used for constant voltage equipment, only need to set the maximum output current. Adjustment Method: 1. Battery under voltage protection adjustment method:(take 12V lead-acid battery as an example, set 10V under-voltage protection, shut off output) Input is connected to regulated power supply adjusted to 10V, adjust under-voltage protection potentiometer (clockwise to increase, counterclockwise to reduce), till the failure indicator (red) light is on. Then when the battery discharge to 10V, it will automatically cut off power supply to protect battery from damage. Note:If not powered by batteries, you can skip this setting. 2. Output voltage adjustment methods:Input is connected to power source (voltage is higher than the under-voltage protection value), the red light is off while blue light is on. Output is connected to multimeter, adjust output voltage potentiometer (clockwise to increase, counterclockwise to reduce) till the required voltage; Note: Normally the red light is off, blue light is on, otherwise there is fault, input under-voltage protection, output over-current protection, output short circuit protection, please troubleshoot and power on again. 2. Output current adjustment methods:(take 12V input to charge 12V lead-acid battery as example, the charging current is 5 A) Input is connected to 12V power supply, turn multimeter to current position, output is connected to multimeter in parallel (red pen to output positive, black pen to negative, short circuit output directly.
