Technical FAQs
1. Does the VPWR module provide isolated power outputs?
Yes, it uses internal isolation barriers to protect downstream electronics.
2. Can VPROH2B operate without redundant power sources?
It can, but GE systems typically recommend dual feeds for reliability.
3. Are these modules hot-swappable?
No—Mark VI modules require system shutdown before removal.
4. What type of diagnostic signals are available?
Status LEDs, system feedback, and fault-state signals to the controller.
5. Is filtering active or passive?
These modules incorporate both active regulation and passive noise filtering.
6. Can the VPWR module tolerate DC ripple?
Yes, within the limits defined for Mark VI power input specifications.
7. What happens during an overvoltage event?
Internal surge arresters and suppression circuits protect downstream boards.
8. Are they backward compatible with earlier Mark IV/V systems?
No, they are dedicated to Mark VI and later architectures.
9. Can these modules withstand turbine enclosure vibration?
Yes, they meet GE’s turbine-grade vibration specifications.
10. Does VPROH2B participate in trip logic?
It contributes protection signals but final trip logic resides in the TMR processors.
