Basic Information

Product Description

⚠️ Safety Note: Please do not use the input ground and output ground of the module together. This causes the current sampling resistance to be bypassed, preventing current adjustment and potentially burning the power supply chip.

Module Highlights

• High Performance: High power, high efficiency, 5A output with low ripple.
• Three-in-One Functionality:
  • Common step-down module with over-current protection.
  • Battery charger for various voltages (Lithium, NiCd, NiMH, solar panels).
  • High-power LED constant current drive module.
• Dual Modes: Supports constant voltage (CV) and constant current (CC) with clear indicator lights.
• Charging Indicators: Visible status for "charging" and "fully charged" when used for batteries.
• Short Circuit Protection: Current limiting protection ensures the module won't burn under short circuit conditions.

Technical Parameters

Scope of Application & Usage

1. General Step-Down Module

• Adjust the constant voltage potentiometer to your desired output.
• Measure output short circuit current with a 10A multimeter and adjust the CC potentiometer to set the overcurrent protection value.

2. Battery Charging

• Determine floating voltage and charge current.
• Adjust output voltage to floating charge level under no-load.
• Set charging current using the multimeter short-circuit method.
• Default lamp turn current is 0.1x of the set charging current.

3. High-Power LED Drive

• Set output voltage to the LED's maximum working voltage.
• Adjust the CC potentiometer to set the specific LED working current.
• Note: Strengthen heat dissipation if using above 3A or 35W.
