Description
DS200PCCAG8ACB Product Overview
The DS200PCCAG8ACB is a Power-Connect / Capacitor-Control (PCCA) interface board used inside GE Mark V Speedtronic and EX2000 medium-voltage drive cubicles. It occupies a double-slot VME position and acts as the high-voltage gateway between the triple-redundant control processor and the IGBT/SCR power bridge.
The DS200PCCAG8ACB is a Power-Connect / Capacitor-Control (PCCA) interface board used inside GE Mark V Speedtronic and EX2000 medium-voltage drive cubicles. It occupies a double-slot VME position and acts as the high-voltage gateway between the triple-redundant control processor and the IGBT/SCR power bridge.
In the drive hierarchy the card sits at the “power-interface” layer:
-
It distributes 24 VDC control power to gate-drive cards,
-
routes ±10 V or 4-20 mA feedback signals (DC-bus voltage, output current, temperature) back to the CPU,
-
and houses snubber capacitors that clamp dv/dt spikes during IGBT turn-off.
All medium-voltage connections are made through 180-pin keyed headers (J1–J6), keeping 480–4160 V wiring away from the low-voltage backplane. Six on-board trim-pots (PL, NL, U, V, W, PR, NR) allow site-specific tuning of snubber damping and regeneration thresholds without software downloads.
Because the board is passive (no processor) and carries conformal coating, it is accepted in safety-related turbine-compressor drives where “simple device” classification avoids additional software V&V.

Typical Applications
In combined-cycle power plants the DS200PCCAG8ACB is installed in Mark V drive cubicles that feed the gas-turbine compressor motor. The snubber network clamps IGBT turn-off spikes while the ±10 V feedback lines report DC-bus voltage to the CPU, keeping EMI within IEEE 519 limits

.
In pipeline booster stations the same card is used in 4.16 kV VFDs that drive centrifugal compressors; the trim pots are adjusted on-site to match the installed 1700 V IGBT modules, ensuring <5 % overshoot during full-load switching
.
Because the board is certified for marine environments, it is also used on off-shore platforms for well-boost compressors where fan-less, high-dv/dt immunity is mandatory .
