IS200TTPWH1A - TTPW Power Conditioning Board | GE Mark VI | B7B

The General Electric IS200TTPWH1A (TTPW) is a Power Conditioning terminal board for GE SPEEDTRONIC™ Mark VI turbine control systems, providing branch circuit protection and distribution between one or more Mark VI rack-mounted +28 V dc power supplies and discrete wiring to peripheral field devices.

TTPWH1A has three 2-pin inputs for +28 V dc from the Mark VI power supply, with diode-OR selection between the three inputs to power the +28 V dc outputs. Outputs are rated 22-30 V dc, 0-0.25 A individually (nine outputs total) and are capable of parallel operation, with high-frequency isolation between inputs and outputs and less than +4 V dc voltage drop at rated current.

For maintenance and procurement teams, IS200TTPWH1A should be matched to the existing Mark VI rack power architecture and peripheral device wiring per GEH-6421 Volume II before ordering a replacement.

Control system parts are provided by GTC Control Solutions, Inc., a wholly owned subsidiary of B7B. Parts are offered in unused, repaired, or remanufactured condition, subject to availability. Each repaired or remanufactured component undergoes functional testing in energized panels, with test reporting and warranty support provided for repair and lifecycle-extension programs.
