Technical Questions Answered
- What is the intermediate voltage in the conversion process?
- The buck-regulator first converts input voltage to 50V DC before final conversion.
- How many controllers can one EPSM module support?
- Each controller (M1, M2, C) requires its own independent IS200EPSMG1A module.
- What documentation covers this module?
- GEI-100462 manual specifically, with additional info in GEH-6632 page 53.
- Can this module handle voltage spikes?
- Yes, the push-pull inverter design provides excellent spike protection.
- Where is this module physically located?
- It mounts in the EPBP backplane beneath the control rack in the cabinet.
