DCDC-M
Product Family
Product Family
Flexible. Modular.
Kolibrik’s DCDC-M Product Family delivers precise, reliable power conversion with a robust architecture — built for versatile deployment across DC power applications, including fuel-cell stacks and other systems requiring modular conversion.
DCDC-M Product Family takes over where higher input voltages push DCDC-S to its limits— and where galvanic isolation between input and output is required.
The DCDC-M Product Family is designed for fast-moving projects — with short lead times and ready-to-use configurations. Whether you're building an application prototype, delivering a small production run, or setting up a training platform, DCDC-M gets you up and running without delays.
Uses 6 modules and fixed output settings — optimized for cost, speed, and plug-and-play simplicity.
Quick & Cost-Efficient
Preconfigured design for lower cost, short lead times, and hassle-free installation — no custom setup needed.
Galvanic Isolation
Electrically isolated input and output for enhanced safety, noise reduction, and system protection.
Higher Input Voltage
Supports input voltages up to 144 V — ideal for demanding industrial and energy systems.
The DCDC-M Product Family is a DC/DC power conversion platform built for the diverse demands of hydrogen fuel cell and other applications. It’s based on standard industrial DC/DC converters — but enhanced with Kolibrik’s custom control electronics.
Out of the box, these converters aren’t designed to scale.
DC/DC Power Converter DCDC-M6-48/126
The DCDC-M Product Family includes one universal model — DCDC-M6-48/126 — designed to cover a broad range of typical use cases.
A custom-configurable variant is available for application-specific requirements.
-
Stand-alone DC/DC converter with fixed output
Preconfigured module with defined voltage and current parameters — ideal for consistent, repeatable use cases. -
Open-frame setup for system integration
Bare-board version optimized for direct integration into existing power architectures or embedded designs. -
Fully customized solutions for series production
Tailored hardware and control electronics for OEM projects, including thermal management, mechanical design, and digital interface integration. - Adaptable Performance
The DCDC-M platform supports both constant voltage and current limitation.

Use Cases
From fuel-cell stacks to BoP and hybrid storage — precision power conversion across your hydrogen system.
Output power conversion
Fuel-cell stack output power conversion for application power (e.g. fixed 24 V or 48 V output)
Balance of Plant (BoP) power supply
Powers pumps, valves, sensors and controls
Pre-conditioning for inverters with incompatible inputs
Matches stack output to inverter input range
Example setup
- 5kW H2FC stack (72..144 V) → DCDC-M (output 48 V) → Inverter (48 VDC → 230 VAC)
