About the IS200EPSMG2AED
The IS200EPSMG2AED is an Exciter Power Supply module created by GE for use in the Mark VI system. The MKVI is one of the last of the Speedtronic series for gas and steam turbine management created by General Electric. While the Speedtronic series has been used for turbine management since 1969, the Mark VI is significantly more advanced than those early systems, using a Windows PC as an HMI or operator interface. This operator interface includes full-color graphics (CIMPLICITY) and Ethernet capabilities.
The IS200EPSMG2AED is one of two EPSM boards used in the Mark VI system. Group one modules (EPSMG1) are used in the thyristor system. The IS200EPSMG2AED board is used in the regulator control. The two boards are similar, but the IS200EPSMG2AED includes an EPSD daughterboard.
The IS200EPSMG2AED is designed to convert the dc-link voltage into the different voltages required for the EX2100 regulator control. The IS200EPSMG2AED supplies +5VDC, +/- 15VDC, and +24VDC. In a simplex system, a single IS200EPSMG2AED board is mounted in the ERBP backplane. In a redundant system two boards are mounted into the backplane (ERBP (M1) and ERRB,(M2/C.))
The IS200EPSMG2AED is built with a faceplate with seven LED lights. The board has a Bicron inductor, a transformer, five transistors with heat sinks, and an additional inductor coil. The board has four more heat sinks located on the board. The board has nine fuses. The daughterboard (EPSD) is connected to the main board using four screws inserted into standoffs. This board includes a backplane connector.
