IS200EPSMG2A GE EX2100, Power Supply Card

Description:

The IS200EPSMG_A Exciter Power Supply Module (EPSM) is used in the EX2100 Excitation Control System and the EX2100 Regulator Control. EPSM Group 1 modules (EPSMG1) are used in the excitation control system and EPSM Group 2 modules (EPSMG2) are used in the regulator control. EPSMG2 includes an IS200EPSDG_A Exciter Regulator Power Supply Daughter board (EPSD) mounted to it.

EPSMG2 converts the dc link bus voltage into the voltages required for the EX2100 regulator control. In simplex systems, one EPSMG2 is mounted in the IS200ERBPH_A Exciter Regulator Backplane (ERBP). In redundant systems, one EPSMG2 is mounted in ERBP (M1) and a second EPSMG2 is mounted in the IS200ERRBH_A Exciter Regulator Redundant Backplane (ERRB, M2/C).

The EPSD that is mounted on EPSMG2 modifies the power input path to allow EPSMG2 to accept higher voltages by increasing the creep and clearance. It also provides a fuse between the regulator power source (dc link) and the buck-regulator.

The EPSMG2 supplies +5 V dc, ±15 V dc, and +24 V dc to the ERBP and ERRB. Power is also supplied to external modules as follows:

• ±24 V dc (P24B/N24B) to power fans, relays, and the dc feedback board

• Isolated +70 V dc (P70) for contact-wetting on the terminal board, dynamic discharge board, and redundant relay board

• Isolated 20 V ac (AC17) to power the IGBT gate and dynamic discharge board

• ±55 V dc (P55/N55) to the ground detector circuits on the options card
