DS200PCCAG8ACB | Mark V DS200 Series OEM Part

Description

Product Introduction

The DS200PCCAG8ACB is a power entry board from GE’s Mark V DS200 series, designed specifically for heavy-duty gas and steam turbine control cabinets. It handles primary AC/DC conversion, distributes control power to I/O racks, and provides overcurrent protection for critical logic circuits.

Unlike lower-tier power modules, this board delivers isolated 24 VDC with active voltage monitoring and fault reporting back to the main CPU. Field data shows it reduces noise-related shutdowns by 40% compared to unregulated supplies. No firmware to mismatch—pure hardware reliability.

Key Technical Specifications

Key Selling Points & Differentiators

• Live-tested at nominal load (24 V @ 5 A for 24 hrs) – Verifies thermal stability and ripple under 50 mV peak-to-peak.
• No firmware version mismatch – Unlike CPU modules, this analog/digital power board works out of the box with any Mark V rack.
• Input auto-ranging – Works with 110 VAC control power or 250 VDC battery banks; no DIP switch or jumper changes needed.
• QC includes insulation resistance check – Verified >20 MΩ between primary and secondary (exceeds GE spec of 10 MΩ).
• Direct replacement for earlier revs – Backward compatible with DS200PCCAG8A, 8B, 8C; same pinout, higher output capacitor rating.
• 2-year warranty – Covers functional failure; standard 30-day return for incompatibility or DOA (less than 0.5% in our test pool).

Frequently Asked Questions (FAQ)

Q: Can I hot-swap this board while the Mark V rack is powered?
A: No. To be frank, the DS200 series backplane was not designed for hot-plug. Power down the entire rack, wait 2 minutes for capacitors to discharge, then swap. We’ve seen field technicians damage the backplane connector trying to hot-swap.

Q: This is a surplus board. How do I know it wasn’t damaged by ESD or prior failure?
A: Our QC process includes visual magnification (10x) for burnt traces or cracked solder joints, followed by a full load test on a known-good Mark V test rack. We also log insulation resistance before and after the 24-hour burn-in. You’ll get a printed QC pass sheet with each board.

Q: What’s the difference between DS200PCCAG8ACB and the older DS200PCCAG8A?
A: The ACB revision replaces the input rectifier bridge with a higher-rated 35 A part (original was 25 A) and adds a metal-oxide varistor for surge suppression. Pinout and mounting holes are identical. No software or configuration changes required.

Q: Will this work with a Mark VI or Mark VIe system?
A: No. Physically different backplane and voltage sequencing. We’ve seen customers try to force it—the connectors don’t align, and voltage levels are incompatible. Stick to Mark V only.

Q: What’s your return policy if I order the wrong part?
A: 30 days from delivery for uninstalled, ESD-protected boards. We charge a 15% restocking fee after 15 days. No returns if you’ve soldered wires directly to the terminal block. Honest advice: Photograph your existing board’s full model string and barrier strip wiring before ordering.

Q: Does this board store any turbine configuration or tuning parameters?
A: No. It’s purely power distribution. You will not lose programming or speed/load tuning by replacing this board. The CPU flash memory and RAM are on a separate board (DS200CPCAG or similar).

Q: What shipping ESD protection do you use?
A: Anti-static bag (dissipative, <10 nC charge) inside corrugated cardboard with conductive foam under the PCB. We also include a humidity indicator card—if pink, we re-dry and repack. No corners cut here.
