LED Driver Constant Current Voltage Regulator for 7-40V to 1.2-35V

This module is a non-isolated, step-down, constant current and constant voltage (CC/CV) charging module. It has the following features:

Input Voltage: DC 7-40V Output Voltage: Continuously adjustable from DC 1.2V to 35V Output Current: 8A maximum (requires cooling fan if power tube temperature exceeds 65 degrees) Constant Current Range: 0.2A to 8A, adjustable Turn Lamp Current: Constant current value * 0.1 (e.g., 3A constant current → 0.3A turn lamp current) Output Power: 300W maximum Conversion Efficiency: Up to 95% Operating Frequency: 300KHz Output Ripple: 20MHz bandwidth Input 24V Output 12V 5A Ripple: Around 50mV, excluding noise Operating Temperature: Industrial grade (-40°C to +85°C) No-Load Current: Typical 20mA (24V to 12V switch) Load Regulation: ±1% (constant) Voltage Regulation: ±1% Dynamic Response Speed: 5% in 200μs Potentiometer Adjustment: Clockwise to increase, counterclockwise to decrease; CV pot controls voltage, CC pot controls current Indicator: Dual-color - red for charging, green for fully charged (no load is green) Output Short Circuit Protection: Yes, constant current

This module is suitable for the following applications: - High-power LED constant current driver - Rechargeable lithium batteries (including ferroelectric), 4V, 6V, 12V, 14V, 24V - Nickel-cadmium and nickel-metal hydride battery pack charging - Solar panels and wind turbines

The module dimensions are 65 x 47 x 23.5 mm, and the package includes 1 DC step-down power converter module.
