Model zasilacza wzbudzenia GE IS200EPSMG1A, dostępny w magazynie

The IS200EPSMG1A is an Exciter Power Supply Module (EPSM) manufactured by General Electric (GE) for the EX2100 Excitation Control system. It is designed for installation in the EPBP backplane and is identified as a power supply module used with the EPDM module. Its hardware identification and backplane mounting location are important when checking replacement requirements for an existing EX2100 control assembly.

Technical Specifications

Module Function and System Position

The IS200EPSMG1A is identified as the Exciter Power Supply Module within the GE EX2100 excitation control platform. Its designated EPBP backplane mounting position distinguishes it from other EX2100 control and interface boards.

The EPSM designation identifies its power-supply role in the exciter assembly. It is associated with the EPDM module, but the available product information does not specify the detailed electrical output ratings, supply input range, or power distribution connections. These values should be checked against the applicable EX2100 hardware documentation before replacement or system configuration.

Power Conversion and Distribution

The module receives a nominal 125 VDC input from the EPDM (Exciter Power Distribution Module) and converts it into regulated DC supply rails for the EX2100 control hardware. According to the EX2100 system documentation, these include +5 VDC, +15 VDC, -15 VDC and +24 VDC.

Additional power distribution includes +/-24 VDC for designated external modules and an isolated +70 VDC supply for contact-wetting circuits on the ECTB and EXTB terminal boards. These separate supply rails support different control, interface and excitation-related circuits.

Backplane Installation and Configuration

The IS200EPSMG1A installs in the EPBP Exciter Power Backplane. Its position must correspond to the intended controller section. GE documentation identifies the M1 section for simplex excitation systems and M1, M2 or C sections for redundant configurations.

The board must be installed in its designated slot. Incorrect insertion can damage the electronics. Replacement procedures and precautions are covered in the product-specific manual GEI-100462.

Frequently Asked Questions

Q: What is the input power source for the IS200EPSMG1A?

A: The module receives 125 VDC from the EPDM. It converts this input into the DC supply voltages required by the EX2100 excitation control hardware.

Q: Can the IS200EPSMG1A be installed in any EPBP slot?

A: No. It must be installed in the designated controller section. The correct position depends on whether the excitation system uses a simplex or redundant configuration.

Q: Is the IS200EPSMG1A interchangeable with other EPSM revisions?

A: Revision identification must be checked before replacement. The IS200EPSMG1A is an A-version board, and compatibility with earlier revisions should not be assumed. Verify the hardware revision and system configuration against GEI-100462 before substitution.
