Hydrogen DC Power Supply
DC Power Supply for Hydrogen Production
Neeltran dc rectifiers are custom designed to meet your hydrogen needs. Whether an indoor or outdoor solution, an oil or water cooled transformer, a compact or walk in rectifier (E-House) we have the ability to meet all of your specifications. Our team builds / designs transformers and rectifiers in its Connecticut facility to provide you a dc power system solution that exceeds your requirements.
Our rectifiers can power Green Hydrogen electrolyser production that uses Proton Exchange Membrane (PEM) technology. Typical hydrogen applications are Fuel, Energy Storage, Energy Generation, and Industrial hydrogen.
Value to the Customer -
Reduced land footprint, ease of installation and lower install cost, no potential for environmental issues in many cases.
Range size from 1MW to 100 MW for electrochemical rectifiers.
Combined Full Current and Full Voltage factory testing of the transformer and rectifier in their actual configuration prior to shipment means quick start ups and improved quality.
