IS200EPSMG2A General Electric Exciter Power Supply Module

Core Technical Specifications

• Brand & Model: General Electric IS200EPSMG2A (Revision A)
• Series: EX2100 Excitation Control
• Product Type: Exciter Power Supply Module (Group 2 for Regulator Control)
• Operating Temperature: -30 to +65°C
• Dimensions: 15.9 cm high x 17.8 cm

• Country of Origin: United States
• Manual Reference: GEI-100462A, GEH-6632

Functional Description

• The IS200EPSMG2A consists of two major sections: a buck regulator and a push‑pull inverter. The buck regulator converts input voltage to an intermediate 50 V DC.
• The push‑pull inverter then converts this intermediate voltage into the required multiple output voltages using a transformer that provides high‑ voltage isolation.
• This module includes an IS200EPSDG_A Exciter Regulator Power Supply Daughter board (EPSD) mounted directly to it.
• The EPSD modifies the power input path to accept higher voltages by increasing creepage and clearance, and it provides a fuse between the DC link source and the buck regulator.
• This revision A model is not backward compatible with earlier non‑A versions.

Output Voltages & Power Distribution

• To Control Backplane: Supplies +5 V DC, ±15 V DC, and +24 V DC to the ERBP and ERRB backplanes.
• ±24 V DC (P24B/N24B): Powers fans, relays, and the DC feedback board.
• Isolated +70 V DC (P70): Provides contact wetting for terminal boards, dynamic discharge board, and redundant relay board.
• Isolated 20 V AC (AC17): Supplies power to IGBT gate drives and the dynamic discharge board.
• ±55 V DC (P55/N55): Delivers power to ground detector circuits on the options card (EROC).

Frequently Asked Questions

• Q: Is this IS200EPSMG2A brand new?
  A: Yes, we supply the IS200EPSMG2A as brand new stock, directly from General Electric manufacturing sources.
• Q: Do you have the IS200EPSMG2A in stock for immediate shipment?
  A: Yes, we maintain in‑stock availability for this model. We can ship your order within 5 days.
• Q: How do you ship the board and which carriers do you use?
  A: We ship via DHL, FedEx, or UPS – whichever suits your location best. We will provide a tracking number once dispatched.
• Q: What is the return policy for this Exciter Power Supply Module?
  A: We accept returns within 30 days. The module must be in its original condition and packaging.
• Q: What is the difference between EPSMG1 and EPSMG2?
  A: EPSMG1 modules are used in excitation control and mount in the EPBP backplane. EPSMG2 modules (like the IS200EPSMG2A) are used in regulator control and mount in ERBP/ERRB backplanes. They accept different input voltages and provide different output sets.
• Q: Is this module backward compatible with older EX2100 systems?
  A: No, the "A" revision indicates this model is not backward compatible with non‑A versions. Check your system requirements carefully.
• Q: Does the package include the EPSD daughter board?
  A: Yes, the IS200EPSMG2A includes the EPSD daughter board already mounted. No additional assembly is required.
• Q: Where can I find installation instructions?
  A: Refer to the GEH-6632 EX2100 Excitation Control User's Guide or manual GEI-100462A for detailed installation and setup procedures.
