1200W 20A DC-DC Boost Converter Module – 8–60V Input to 12–83V Adjustable Output

Upgrade your power conversion projects with the 1200W 20A DC-DC Boost Converter Module from Electronics Hub. This high-power, non-isolated step-up converter is designed to increase a lower DC input voltage to a higher adjustable DC output voltage.

With an advertised input range of 8–60V DC and an adjustable output range of 12–83V DC, this module provides flexible voltage conversion for electronics development, battery-powered systems, high-power LED projects and custom DC power supply applications.

The module features a large toroidal copper inductor, multiple electrolytic capacitors, aluminium heatsinking and adjustable voltage and current controls. Its constant-voltage (CV) and constant-current (CC) adjustment functions provide greater control over compatible DC loads.

The advertised 1200W and 20A ratings represent maximum specifications, not guaranteed continuous output under every operating condition. Actual power delivery depends on input voltage, output voltage, efficiency and cooling.

Key Features

• Wide DC Input Range: Designed for an advertised input range of 8–60V DC. Check the minimum startup voltage of your particular board revision.

• Adjustable Output Voltage: Provides adjustable DC output from 12V to 83V.

• High-Power Conversion: Advertised maximum power rating of 1200W, subject to input power and thermal limitations.

• High Current Capability: Advertised maximum current of up to 20A, with continuous operating current dependent on cooling and voltage conversion ratio.

• Constant Voltage Control (CV): Adjust the output voltage according to your application's requirements.

• Constant Current Control (CC): Provides adjustable current limiting for compatible loads.

• Large Toroidal Inductor: Supports the module's switching power-conversion circuit.

• Multiple Electrolytic Capacitors: Provide energy storage and output filtering.

• Aluminium Heatsink: Helps dissipate heat during high-power operation.

• Screw-Terminal Connections: Designed for convenient DC input and output wiring.

Technical Specifications

Specifications are based on matching HSKJ-HS202 distributor listings. Some electrical limits vary between module revisions. Verify the physical product before publishing final specifications.

Adjustable Constant Voltage (CV) and Constant Current (CC)

This module offers two adjustment functions for flexible power control.

1. Constant Voltage (CV)

The voltage adjustment control allows you to set the required output voltage between the supported limits.

Applications include:

• Adjustable DC power supplies

• Electronics testing

• Voltage conversion for compatible equipment

• Custom power electronics projects

2. Constant Current (CC)

The current adjustment control allows you to establish a current limit for compatible loads.

Applications include:

• High-power LED circuits

• Current-limited electronics experiments

• Custom DC power systems

Always set and measure the required output before connecting your load.

High-Power Performance and Cooling

The 1200W rating is an advertised maximum. Actual available output power depends on the input supply and conversion efficiency.

For example, at 24V input and 20A input current, the input power is 480W. The available output power will be lower after conversion losses.

For sustained high-current applications:

• Provide adequate ventilation.

• Use an appropriately rated external cooling fan where required.

• Use thick, appropriately rated copper wiring.

• Avoid exceeding the module's current and thermal limits.

• Monitor heatsink temperature during demanding operation.

Some matching product versions recommend additional fan cooling above 15A input current or when operating at high output loads.

Typical Applications

1. High-Power LED Lighting

Suitable for compatible high-power LED systems requiring an increased DC voltage and adjustable current control. Check LED forward voltage and current requirements.

2. Solar Power Projects

Can be used in suitable DC voltage-boosting sections of solar electronics projects. This module is not a complete solar charge controller or MPPT controller.

3. Battery-Powered Electronics

Increase the DC voltage from a compatible battery source for higher-voltage electronics projects. Use an appropriate BMS and battery protection system.

4. Adjustable DC Power Supply

Build custom power conversion setups for electronics testing, prototyping and development.

5. Robotics and Automation

Use in compatible robotics and automation projects requiring higher DC voltage from a lower-voltage source.

6. Industrial Electronics

Suitable for custom DC power conversion and electronic equipment development within the module's electrical limits.

7. DIY Power Electronics

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

Input and Output Connections

Connect the power supply and load according to the actual PCB terminal markings.

• IN+ : Positive DC input

• IN− : Negative DC input

• OUT+ : Positive DC output

• OUT− : Negative DC output

Check the PCB markings before wiring because terminal placement can vary between revisions.

Installation and Safety Precautions

1. Verify the module's minimum startup voltage before connecting the power source.

2. Never exceed the specified input voltage range.

3. Check input polarity carefully before powering the module.

4. Install an appropriately rated external fuse.

5. Use thick, low-resistance copper wires for high-current applications.

6. Adjust the output voltage using a multimeter before connecting the load.

7. Set the current limit before connecting sensitive equipment.

8. Provide adequate cooling and ventilation.

9. Do not reverse the input polarity. The module does not provide reverse-polarity protection.

10. Never deliberately short-circuit the output terminals to test current adjustment.

11. Disconnect the power supply before changing wiring.

12. Do not exceed the advertised power, current or temperature limits.

Important: This is a non-isolated boost converter. It increases DC voltage; it does not provide electrical isolation or step-down conversion.
