1500W 30A DC-DC Boost Converter – 10–60V to 12–90V Adjustable CC/CV Power Supply Module

The 1500W 30A DC-DC Boost Converter is a high-power adjustable step-up power supply module designed to increase DC input voltage for demanding electronics and power conversion applications.

Featuring a wide 10V–60V DC input range and continuously adjustable 12V–90V DC output, this module provides flexible voltage conversion for battery-powered systems, LED lighting projects, solar electronics, DIY power supplies and custom electronics development.

The module supports Constant Voltage (CV) and Constant Current (CC) adjustment, allowing users to regulate output voltage and set a current limit according to the requirements of compatible loads.

Its high-current design includes a large power inductor, heatsinking, electrolytic capacitors, screw-terminal connections and protection circuitry.

Important: The 1500W figure is an advertised maximum input-power class, not a guaranteed continuous output rating. Actual output power depends on input voltage, current, conversion efficiency, voltage difference and cooling. The maximum listed output current is 20A, and additional cooling is recommended above 15A.

Technical Specifications

Specifications should be checked against the exact supplied board revision. Some versions have different fan, mounting-column and heatsink configurations.

Understanding CC and CV Adjustment

Constant Voltage (CV) Mode

The CV adjustment allows users to set the desired output voltage within the supported range.

Suitable for:

• Adjustable DC power supplies

• Electronic equipment requiring higher DC voltage

• Battery-powered electronic projects

• Custom voltage conversion systems

Constant Current (CC) Mode

The CC adjustment allows users to set a current limit for compatible loads.

Suitable for:

• High-power LED applications

• Current-limited electronic circuits

• Compatible battery charging systems

• Electronics testing and development

Always configure the output voltage and current limit using appropriate test equipment before connecting sensitive loads.

High-Power Performance and Cooling

The module is designed for high-current power conversion, but actual output capability depends on the difference between input and output voltages.

As the voltage difference increases, available output current may decrease.

For better operating performance:

• Provide adequate ventilation.

• Use the fan-equipped version where applicable.

• Install additional cooling when operating above 15A.

• Use appropriately rated pure copper wires.

• Keep electrical connections tight.

• Monitor operating temperature under high loads.

• Avoid operating continuously at the advertised maximum rating without verifying thermal performance.

Protection Functions

The listed SZ-BT07CCCV-D1 version includes the following protection functions:

Input Overcurrent Protection: Helps protect the module when input current exceeds its supported operating limit.

Input Reverse-Polarity Protection: Helps protect the input circuit from incorrect battery polarity.

Low-Voltage Protection: Adjustable low-voltage protection helps prevent excessive battery discharge.

Short-Circuit Protection: Listed versions include input fuse-based protection.

Protection implementation and ratings can vary between revisions. External fusing is still recommended.

Typical Applications

1. High-Power LED Lighting

Use the adjustable output and current-limiting function with compatible high-power LED systems. Match the LED voltage and current requirements before connection.

2. Solar Power Electronics

Suitable for voltage-boosting sections of compatible solar power projects. It is not a standalone MPPT solar charge controller.

3. Battery-Powered Systems

Increase DC voltage from compatible battery sources for custom electronics and power conversion applications. Use a correctly rated battery management system.

4. DIY Adjustable Power Supply

Develop adjustable DC power systems for electronics laboratories, workshops and technical projects.

5. Electric Vehicle and Automotive Electronics

Use in compatible DC power conversion projects where input voltage, output voltage and current requirements are within specifications.

6. Industrial Electronics

Suitable for custom power electronics, automation experiments and compatible industrial DC applications.

7. Electronics Research and Development

A useful option for engineers, technicians, students and electronics enthusiasts developing high-power DC systems.

Input and Output Wiring

The module uses screw-terminal connections.

Identify the input and output terminals using the actual PCB markings or supplied wiring diagram before installation.

• IN+ : Positive DC input

• IN− : Negative DC input

• OUT+ : Positive DC output

• OUT− : Negative DC output

Terminal placement can vary between PCB revisions. Never rely on a generic diagram without checking the markings on your actual board.

Installation and Safety Instructions

1. Confirm the input voltage is between 10V and 60V DC.

2. Check the positive and negative input connections carefully.

3. Use suitable input fusing and correctly rated cables.

4. Connect the module to a suitable DC source.

5. Measure the output voltage using a multimeter.

6. Adjust the CV setting before connecting your load.

7. Configure the CC setting according to the load requirements.

8. Ensure sufficient cooling and airflow.

9. Avoid output short circuits and reverse-polarity connections.

10. Disconnect the input supply before changing wiring.

11. Do not exceed the module's maximum input or output current.

12. For battery charging, use a compatible battery chemistry, correct charge voltage and suitable independent battery protection.

Safety Notice: This is a non-isolated boost converter. It does not provide electrical isolation and cannot step down voltage. The output voltage must be higher than the input voltage for normal boost operation.
