Adjustable CC/CV Boost Converter up to 1200W for High-Power LED Modules, Battery Systems and DC Power Supplies

This high-power DC-DC boost converter is designed to increase and precisely regulate DC voltage for a wide range of electronic and electrical applications. The module features adjustable output voltage and current limiting (CC/CV), making it suitable for powering various loads and building adjustable DC power supply systems.

The converter operates with an input voltage range of 10V to 60V DC and provides an adjustable output voltage from 12V to 83V DC. The factory default output voltage is typically set to approximately 19V, but it can be adjusted according to your requirements using the built-in V-ADJ potentiometer.

The module supports a maximum input current of up to 20A and an output current of up to 18A, with a separately adjustable constant-current range of 0.5–18A. This allows precise current limiting when powering high-power LED modules, charging compatible battery systems and operating various electronic devices.

Thanks to its high-frequency switching technology and 150kHz operating frequency, the converter achieves an efficiency of approximately 92–97%, depending on input voltage, output voltage and load conditions. Its high-power design incorporates MOSFET switching components, a large heatsink and several protection functions for more reliable operation.

Another useful feature is the adjustable low-input-voltage protection (UVLO), which allows the shutdown threshold to be set between 9V and 50V. This function is particularly useful when operating from batteries, helping prevent excessive battery discharge.

The module features high-current screw terminals for convenient wiring, four mounting holes and a compact design measuring 130×52×53mm. It is suitable for laboratory and DIY power supplies, high-power LED lighting systems, electronic development and other applications requiring increased DC voltage.

Converter Adjustment Guide:

The module features two separate adjustment potentiometers:

• V-ADJ (Voltage Adjustment): Controls the output voltage. Adjustment is performed using a flat-head screwdriver, preferably with no load connected. Due to the large output filtering capacitors, reducing the voltage may take some time.

• A-ADJ (Current Adjustment): Controls the maximum output current. Initially, turn the potentiometer counterclockwise approximately 30 turns to reach its minimum setting. Then connect a suitable load and gradually increase the current to the required value while monitoring it with an ammeter.

Protection Functions:

• UVLO – Under-Voltage Lockout: The RV1 trimmer sets a threshold between 9V and 50V. When the input voltage falls below the selected level, the converter stops boosting the output voltage.

• Input Overcurrent Protection: Activates at approximately 25A and limits converter operation.

• Short Circuit Protection: An integrated 30A fuse is provided. Do not use a direct output short circuit to adjust the current limit.

• Reverse Polarity Protection: Implemented using a power MOSFET component.

Important Usage Information:

1. Power Limitations: Maximum power depends on input voltage and available input current. At 12V and 20A, the theoretical input power is 240W; at 24V it is 480W; at 36V it is 720W; and at 60V it is 1200W. Actual output power will be lower due to conversion losses and thermal limitations.

2. Cooling: Forced-air cooling with a fan is required when the input current exceeds 15A. Additional cooling is also necessary for continuous output currents above 10A.

3. Wiring: Use appropriately sized, high-quality copper wires suitable for the operating current. Ensure that all screw terminal connections are secure to prevent overheating.

4. Battery Charging: The module provides CC/CV regulation but is not a dedicated battery charger. When charging batteries, the correct voltage and current must be configured according to the battery chemistry and configuration, with all required protection measures in place.

5. Safety: The output voltage can reach 83V DC. Use appropriate electrical insulation, fuses and protection against accidental contact with exposed terminals.
