The Honeywell 600U / 600U-HV (600 W) specifies a hydrogen inlet of 12 – 18 psi (≈0.8–1.2 barg) 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:
What regulator does the 600U / 600U-HV need?
A two-stage regulator fitted to 12 – 18 psi (≈0.8–1.2 barg) at the stack inlet — held to ±0.1 bar as standard — with flow sized at 10 SLPM, rated for 350–500 bar cylinder supply. Single-stage units drift as the cylinder empties; the HDRX-R's second stage works from a near-constant intermediate pressure, so the 600U / 600U-HV's inlet window holds from full cylinder to reserve. Build it in the configurator — the part number compiles as you go.

Fitted outlet setpoint
1 barg — inside the 600U / 600U-HV window, held to ±0.1 bar as standard
The 600U / 600U-HV specifies a hydrogen inlet of 12 – 18 psi (≈0.8–1.2 barg) per its manufacturer datasheet. The fitted MEYER configuration is HDRX-R350-100-10: outlet set inside that window and held to ±0.1 bar as standard, flow sized at 10 SLPM (sized).
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 original HDRX-R450 450-bar drone regulator line is available today. The next-generation configured HDRX-R platform is in its development programme: configuration quotations are open now, and qualification units are planned for 2027 Q2. Your quotation carries your exact configuration.
