The 400V 500A Hydrogen Electrolysis Rectifier supplies 200 kW of adjustable DC power for higher-voltage electrolyzer stacks operating at moderate current.
The 400V 500A Hydrogen Electrolysis Rectifier provides a defined DC source for electrolyzer integration, supporting stable stack operation while cooling, current control, communication and protection are matched to the project duty.
A balanced rating for series cells
Series-connected cells raise the stack voltage while sharing the same current. Stable regulation lets the plant control the electrical operating point through startup and steady production. Stack efficiency and gas output remain functions of cell design, temperature, pressure, electrolyte or membrane condition and the wider balance of plant.

Confirm the operating envelope
Provide cell count, minimum and maximum stack voltage, normal current, temporary overload needs and ramp limits. The rectifier should cover changing operating conditions without excessive unused capacity.
Safe system coordination
External permissives can verify circulation, cooling and gas-handling readiness before output starts. Remote setpoints, feedback, alarms and fault records can connect to the supervisory controller.
