IS200TTPWH1A

IS200TTPWH1A is a Power Conditioning Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Gas Turbine Control Systems. The Power Conditioning (TTPWH1A) terminal board power conditioning board offers discrete wiring to auxiliary devices as well as branch circuit protection and distribution between one or more Mark* VI rack-mounted +28 V dc power sources. The Mark VI power supply's three 2-pin inputs for the H1A are for +28 V dc. To power the +28 V dc outputs, it offers diode OR selection between the three inputs. The outputs have individual ratings of 0 to 0.25 A, 22 to 30 V dc, and they can operate in parallel. When supplying the rated current, the voltage drop is less than +4 V dc and there is good frequency isolation between the inputs and the outputs.

INSTALLATION:

Plugs P1, P2, and P3 are connected to three 28 V dc supplies that are routed from I/O racks R, S, and T. An analog input board receives the power monitoring signals that are attached to the top terminal block (TB1). The lower terminal block is where the secondary voltage outputs are connected (TB2).

The Mark VI rack-mounted +28 V dc power supply distribution and branch circuit protection provided by the TTPWH1A power conditioning board are discrete connections to peripheral devices. The Mark VI power supply's three 2-pin inputs for the H1A are for +28 V dc. To power the +28 V dc outputs, it offers a diode or option amongst the three inputs. The outputs have individual ratings of 0 to 0.25 A, and 22 to 30 V dc and they can operate in parallel. When supplying the rated current, the voltage drop is less than +4 V dc and there is good frequency isolation between the inputs and the outputs.
