Product description
Model IS200FGPAG1A is a grid pulse amplifier card manufactured by GE Energy as part of the LS2100 Static Start control system. The main function of the grid driver card is to monitor the status of the silicon controlled rectifier (SCR) and switch the power supply within the LCI. The board typically converts the AC input to the DC voltage required for gated and status functions. It can produce many different DC voltages, for example, will produce 25 VDC for the gate "back gallery" voltage.
The IS200FGPAG1A accumulates various voltage information from connected FHVA boards. The IS200FGPAG1A was mostly out of date at the time, but could sometimes be found on the market. The model can detect undervoltage in the grid power supply. If the undervoltage falls off and cannot be repaired, the FCGD, FGPA, and fiber optic cables may need to be replaced.
The best manual to use with this model is the GEH-6373 Load Commutator Inverter Owner's manual. Any questions about the IS200FGPAG1A model can be contacted directly by phone or email to our staff.

The IS200FGPAG1A is a grid pulse amplifier board developed by General Electric. It is part of the EX2100 excitation system. The FGPA is the LCI's gate driver, switching power supply, and SCR status monitor. The LCI controller sends gating commands to the board (via fiber optic cable). Each FGPA provides sufficient gate power and duration for one phase of the SCR bridge. It is sent to the CT on the FHVA board, which interfaces with the SCR.
trait
The switching power supply circuit converts the AC input to the AC control voltage required for status and gating functions. It receives 120 V AC input from the power supply and outputs the following voltages:
P5 (4.7-5.1 V dc) Logical power supply
No P15 monitoring (13.5-14.5V DC)
P40 (25 V dc) for rear gallery doors
To start the door, use P90 (80 V dc)
