GE DS200PCCAG6A

Key Technical Parameters

Advantages & Core Features

• 6A capacity – the “step-up” from 5A – The DS200PCCAG6A provides 20% more capacity than the 5A models, supporting Mark V configurations with 14-20 analog inputs, 14-20 digital I/O, 2-3 communication boards, and dual processor modules – scenarios where the 5A boards are marginal but the 7A DS200PCCAG2A may be slightly oversized. This capacity is particularly useful for incremental I/O expansions that push the +5V load just over the 5A threshold.

• Improved efficiency over 5A models – At 79% efficiency (vs. 78% on 5A models), the DS200PCCAG6A generates less heat per watt delivered, improving reliability in moderately populated racks.

• Higher surge protection than 5A models – 2.2kV surge rating (vs. 2kV on 5A models) provides better resilience against lightning-induced transients and switching surges.

• Compact 1-slot form factor – Fits in any standard Mark V slot without requiring adjacent empty space – critical for upgrading existing racks without reconfiguring module placement.

• Simple AC-only input – No DC infrastructure required; operates directly from standard 115 VAC plant power.

• Cost-effective mid-range option – Priced between the 5A and 7A models, the DS200PCCAG6A offers a tailored solution for installations with loads that fall in the 5-6A range, avoiding the expense of higher-capacity boards.

• Basic LED diagnostics – Four LEDs provide immediate visual status: AC input present, +5V output healthy, current limit active, and general fault.

Application Cases

• Mid-sized gas turbine upgrade – A 250 MW combined-cycle plant added 6 additional analog input channels for bearing temperature monitoring. Total +5V load increased from 4.3A to 5.4A. The original DS200PCCAG1A (5A) was insufficient, but the DS200PCCAG6A (6A) provided adequate headroom without the expense of the 7A model.

• Industrial steam turbine with modest expansion – A food processing plant added two MODBUS communication boards for integration with new plant SCADA. The +5V load rose to 5.6A. The DS200PCCAG6A was selected over the DS200PCCAG2A (7A) to save cost, as the 6A capacity provided sufficient margin (0.4A).

• Gas compressor station – A pipeline facility with three compressor trains used the DS200PCCAG6A in their control racks after a minor I/O upgrade. The 6A capacity supported dual processor boards and 16 I/O modules with comfortable 0.3A margin. The board’s 79% efficiency reduced cooling requirements compared to the 5A model operating near its limit.

• Hydroelectric upgrade – A dam facility replaced aging 5A boards with the DS200PCCAG6A as part of a control system refresh. The additional capacity allowed a modest I/O expansion without another power supply upgrade.

Comparison with Related Variants

Key Takeaway: The DS200PCCAG6A occupies a narrow but useful niche in the Mark V power converter family. It provides a tailored solution for installations where the +5V load falls between 5A and 6A – a scenario that is common during incremental I/O expansions. However, the 7A DS200PCCAG2A is typically not much more expensive and provides greater headroom for future growth, making the DS200PCCAG6A a less common choice. There is no conformally coated or diagnostically capable version of the 6A model – if environmental protection or advanced diagnostics are required, you must choose the coated 5A options (if load allows), the coated 7A DS200PCCAG2ACB, or the coated 10A DS200PCCAG10ACB.

Selection Suggestions

1. Calculate your +5V load accurately – This is the critical decision factor. Select the DS200PCCAG6A if the total is:

   • Between 5A and 6A continuous – ideal range for the 6A capacity.

   • Between 6A and 6.5A – the 6A board may work if peak loads are short, but consider the 7A DS200PCCAG2A for safety margin.

   • Under 5A – choose the 5A model to save cost.

2. Confirm AC power availability – The DS200PCCAG6A accepts 115 VAC only. If your facility provides 230 VAC or 125 VDC, you need an external transformer or must select the dual-input DS200PCCAG10A variant.

3. Assess environmental conditions – The DS200PCCAG6A has no conformal coating. For clean indoor control rooms, this is acceptable. For harsh environments, you must choose the coated 5A options (if load allows), the coated 7A DS200PCCAG2ACB, or the coated 10A DS200PCCAG10ACB.

4. Check slot availability – The 1-slot form factor is a key advantage. The DS200PCCAG6A fits in any position.

5. Evaluate cooling capacity – The DS200PCCAG6A dissipates approximately 38W at full load. Ensure your rack provides at least 80 CFM airflow.

6. Evaluate future expansion – If you anticipate adding more I/O modules, consider whether the DS200PCCAG6A will still have sufficient margin. The 7A DS200PCCAG2A provides more headroom for minimal additional cost.

7. Procurement – The DS200PCCAG6A is rare. Purchase from reputable suppliers offering functional testing (full-load burn-in for 24 hours), ripple/noise measurements, and a 1-year warranty. Lead times: 6-10 weeks.

8. Stock spares – Maintain one on-site spare for critical applications.

Important Precautions

• Power down completely – De-energize rack; wait 5 minutes for capacitor discharge (1,100 µF). Hot-swapping not supported.

• ESD protection – Use wrist strap and anti-static mat.

• AC input only – Do not apply DC voltage – board will be damaged.

• Overtemperature reset – Red FAULT with OTP requires 15-minute cool-down, then manual power cycle.

• Cooling requirements – 80 CFM minimum.

• Fan replacement – Replace 40mm fan every 4 years. Use GE-specified fans (5.5 CFM minimum at 50°C).

• Cleaning – Use compressed air only (max 50 PSI, 30 cm distance). No liquids.

• Storage – Store at 10-30°C, 20-50% RH. Rotate every 24 months.

• Fault diagnosis – If red FAULT persists after cool-down and power cycle, test for shorts; if none, board requires repair or replacement.

Final Expert Recommendation

The DS200PCCAG6A is a specialized 6A power converter for Mark V installations with +5V loads between 5A and 6A. It offers a tailored solution for incremental I/O expansions that push the 5A model to its limit, providing 20% more capacity at a modest price increase. The “A” revision brings improved efficiency (79% vs. 78% on 5A models), higher surge protection (2.2kV vs. 2kV), and the useful current limit LED.

However, the DS200PCCAG6A is a less common choice because:

• The 7A DS200PCCAG2A is typically available at a similar price point and provides greater headroom for future expansion.

• There is no coated or diagnostically capable version of the 6A model.

• Its narrow capacity range makes it less versatile than the 5A or 7A options.

Select the DS200PCCAG6A when:

• Your +5V load is accurately calculated between 5A and 6A

• You have a reliable source for this specific variant

• You are certain no further I/O expansion will occur

• Budget constraints make the 7A model less attractive

For most applications, the DS200PCCAG2A (7A) is the more prudent choice, providing additional headroom for future growth with minimal cost difference. For loads under 5A, the DS200PCCAG1A is more cost-effective. For harsh environments, choose the coated options (DS200PCCAG1ABB, DS200PCCAG2ACB, or DS200PCCAG10ACB depending on load).

When sourcing the DS200PCCAG6A, ensure functional testing is performed and verify authenticity. With proper installation and maintenance, this board will provide dependable service for Mark V turbine control systems with modest power requirements.
