Module Specifications:

Module Name: 500W Step-Down Constant Voltage/Current Adjustable Power Module

Module Type: Non-isolated step-down module

Input Voltage: 12-95V

Output Voltage Range: 1.5-90V (Step-down only; cannot boost voltage. Output voltage must be lower than input voltage)

Input/Output Voltage Difference: 2V

Constant Output Current: 0.3–18A (continuously adjustable)

Rated Output Current: 15A

Rated Output Power: 400W

Input Overvoltage Protection: None (overvoltage prohibited)

Operating Temperature: -10°C to +65°C

Operating Frequency: 120kHz

Conversion Efficiency: Up to 96% (efficiency depends on input/output voltage, current, and voltage difference)

Short-Circuit Protection: Yes (constant current protection)

Input Reverse Polarity Protection: Yes (MOSFET reverse connection)

Output Reverse Current Protection: No (when charging batteries or connecting inductive loads like motors, a reverse protection diode must be added)

Precautions:

1. If input voltage exceeds 36V, first set the ON/OFF switch to OFF. After connecting wires and applying power, switch to ON (to prevent sparking during wiring).

2. This is a buck converter; output voltage must be lower than input voltage.

3. Under natural cooling, power does not exceed 400W and current does not exceed 15A. Power is limited. If output voltage is high or input/output voltage difference is large, reduce current usage.

4. Add a cooling fan if current exceeds 15A or power exceeds 400W.

Voltage/Current Adjustment Method: (Tools required: multimeter, flathead screwdriver)

Voltage Adjustment: Turn the blue potentiometer on the power board clockwise to increase voltage or counterclockwise to decrease it.

Output Current Adjustment: Set multimeter or ammeter to 20A or 10A range. Adjust power supply voltage to 5V. Turn constant-current potentiometer counterclockwise approximately 10 turns to minimize current. Short-circuit output with multimeter, then adjust potentiometer clockwise to desired current value.

The module employs low-side current detection. Do not directly short the input negative terminal to the output negative terminal with a wire. Shorting the negative terminals will prevent constant current operation, potentially damaging both the power supply and the device requiring constant current.

This module is a step-down power supply capable only of voltage reduction, not increase. The input voltage must always be higher than the output voltage.
