Smarter Power Conversion
For the last six variants, the modules offer flexible power distribution. They can operate as a combined single power source or split their output between two separate power supply branches, allowing for different power ratios tailored to your specific needs.
Need constant voltage? Prefer current control? With DCDC-S, you can do both — and switch between them dynamically.
And yes, it’s all digitally controllable and monitorable, giving you real-time insights and remote configurability for complex or distributed power architectures. That includes setups with system batteries, peak-shaving logic, or multiple hydrogen sources running in parallel with individual current contributions.
Adaptable Performance
The DCDC-S platform supports both constant voltage and constant current operation, including current limitation. This makes it ideal for systems with a battery buffer, where the converter can intelligently switch modes depending on the battery’s state of charge and real-time power demand.
The current control mode also enables smart parallelization of multiple power sources — each source can be activated independently and contribute a different current or power level. That gives you precise, distributed control across complex architectures.

Use Cases
From fuel-cell stacks to BoP and hybrid storage — precision power conversion across your hydrogen system.
- Stack output regulation — Stabilizes variable output for downstream use
- Balance of Plant (BoP) power supply — Powers pumps, valves, sensors and controls
- Battery Peak-Shaving — Intelligent mode switching based on battery charge and real-time load — constant voltage or current as needed.
- Multi-stack hydrogen power sources — Combines multiple stacks with individual control
- Electrolyzer supplies with precise current control — Delivers accurate, limited current for efficiency
- Pre-conditioning for inverters with incompatible inputs — Matches stack output to inverter input range
Example setup
H2FC stack (35–72 V) → DCDC-S (output 48 V) → inverter (48 VDC → 230 VAC)
