What Is the 9-36V to 24V 25A 600W Waterproof DC-DC Regulator Module?

This waterproof DC-DC step-up/step-down (buck-boost) regulator module converts a wide input range of 9-36V DC into a stable 24V DC output, delivering up to 25A continuous current for a total output power of 600 watts. Unlike simple buck converters that can only reduce voltage, this module's buck-boost topology handles input voltages both below and above the 24V target -- it will boost a 12V battery up to 24V or buck a 36V solar array down to 24V, automatically selecting the correct mode. The fully potted, sealed aluminium enclosure with integrated heatsink fins provides IP68-level waterproofing, making it suitable for outdoor installations, marine environments, vehicle-mounted systems, and industrial equipment exposed to washdown, rain, or high humidity.

In short: A rugged, sealed 600W DC-DC converter that turns any 9-36V DC source into a clean, regulated 24V 25A output -- ideal for powering 24V equipment from 12V or 24V battery banks in trucks, boats, solar installations, and industrial machines. Supplied new by koeed.com.

Technical Specifications

The 600W rating assumes adequate heatsinking via the enclosure's fins and natural convection airflow. For continuous 600W operation in a confined space, ensure free air circulation around the enclosure. Derate output current by approximately 30% if operating in ambient temperatures above 50 degrees C. Always size your input wiring for the input current (which will be higher than the output current when stepping up from a lower voltage).

Typical Applications

• Vehicle-Mounted Equipment: Power 24V communication radios, LED light bars, or industrial monitors from 12V or 24V truck/bus electrical systems
• Solar Power Systems: Regulate variable solar panel output (often 18-36V) down to a clean 24V bus for battery charging controllers or direct DC loads
• Marine Electronics: Supply stable 24V to navigation instruments, radar systems, and autopilot computers from 12V or 24V battery banks
• Industrial 24V Rail: Create a local 24V supply from a 12V backup battery or a variable DC source in factory automation panels
• Outdoor LED Signage: Power 24V LED billboard modules from available 12-36V DC infrastructure, protected from rain and dust by the sealed enclosure
• Construction Site Power: Run 24V tools or lighting from heavy equipment 12V/24V electrical systems or portable battery packs

Frequently Asked Questions

What happens if my input voltage drops below 9V?

The module has an undervoltage lockout (UVLO) that shuts down the output when the input falls below approximately 9V to protect the converter and the load from unstable operation. The output will automatically restart when the input voltage recovers above the threshold. If your application involves engine cranking (where 12V battery voltage can sag to 8V or lower), add a small hold-up capacitor bank or a secondary battery to bridge the dropout.

Can I adjust the output voltage to something other than 24V?

This module is factory-set to 24V output and is fully potted for waterproofing, so the output voltage is not user-adjustable (the adjustment potentiometer, if present, is sealed inside the potting compound). If you need a different fixed output voltage (12V, 19V, 48V, etc.), contact KOEED -- we can source fixed-output modules in a range of voltages.

Do I need to add external fusing or protection?

Yes. While the module includes basic over-current and short-circuit protection, good engineering practice calls for a fuse or DC circuit breaker on the input side, rated at 125% of the maximum expected input current. For a 12V input delivering 600W output, the input current can reach 55-60A (accounting for conversion efficiency), so a 70-80A fuse is appropriate. On the output side, a 30A fuse protects the wiring to the load. Always size wiring for the maximum continuous current with a reasonable safety margin.

Can multiple modules be connected in parallel for more current?

Paralleling DC-DC converters is generally not recommended unless the modules are specifically designed with current-sharing circuitry. Without active load balancing, one module will take most of the load and may overheat or enter protection mode while the other idles. If your application requires more than 600W at 24V, consider a single higher-power converter or use separate modules to power independent load groups (e.g., one module for 24V lighting, another for 24V controls).

How do I mount and wire this module in a wet environment?

The enclosure has mounting flanges or brackets for screw-down installation. Mount it with the heatsink fins oriented vertically to promote natural convection airflow. For wiring, use marine-grade tinned copper cable with adhesive-lined heat-shrink crimp terminals at the module's input and output studs. Apply a dab of dielectric grease to the terminal connections before tightening to prevent corrosion. Even though the module is sealed, position it so water does not pool around the terminals and cable entries.
