The Spectronik Protium-300 (300 W) specifies a hydrogen inlet of 0.4 – 0.7 bar in its manufacturer datasheet. There is no universal fuel-cell regulator — outlet pressure and flow must be fitted to the stack. This is the MEYER configuration fitted for it:
HDRX-R350-2S-SS-O0.55-F5-FC:P300
Fitted outlet setpoint
0.55 barg — inside the Protium-300 window, held to ±0.1 bar as standard
The Protium-300 specifies a hydrogen inlet of 0.4 – 0.7 bar per its manufacturer datasheet. The fitted MEYER configuration is HDRX-R350-2S-SS-O0.55-F5-FC:P300: outlet set inside that window and held to ±0.1 bar as standard, flow sized at 5 SLPM (datasheet).
Can I use it with cylinder pressures above 350 bar?
Yes — the same fitted outlet and flow are available in 400, 450 and 500 bar supply classes (HDRX-R400/R450/R500); select the supply class in the configurator.
Is the regulator available now?
The HDRX-R is in its development programme: configuration quotations are open now, and qualification units are planned for 2027 Q2. Your quotation carries your exact configuration.
