DS200PCCAG7AG GE

Key Technical Parameters

Advantages & Core Features

• 7A capacity with enhanced thermal performance – Provides the same 7A capacity as the standard DS200PCCAG7A, but with a larger heatsink, improved thermal interface material, and optimized airflow channels that allow operation at up to +55°C ambient (vs. +50°C on standard models). This is particularly valuable for racks located in warm control rooms or outdoor enclosures.

• Extended temperature range – The DS200PCCAG7AG is rated for 0 to +55°C ambient, offering 5°C additional headroom compared to the standard DS200PCCAG7A. This reduces the risk of overtemperature shutdowns in warm environments.

• Improved thermal derating – At high ambient temperatures, the DS200PCCAG7AG maintains full 7A capacity up to +50°C and derates more gracefully above that, whereas standard models may begin derating at lower temperatures.

• Same electrical specifications – All electrical parameters (efficiency, surge protection, output regulation) are identical to the DS200PCCAG7A – only the thermal design is enhanced.

• Compact 1-slot form factor – Despite the larger heatsink, the DS200PCCAG7AG still fits in a standard 1-slot width (though the heatsink may extend slightly higher). No adjacent slot clearance is required.

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

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

Key Differences vs. DS200PCCAG7A (Standard 7A)

Key Takeaway: The DS200PCCAG7AG is a thermally enhanced version of the DS200PCCAG7A, offering extended operating temperature range and improved heat dissipation at the cost of higher weight, limited availability, and increased price. It is specifically designed for installations where cooling is marginal or ambient temperatures are elevated.

Application Cases

• Warm control room installation – A Middle Eastern combined-cycle plant with control room temperatures frequently reaching 48°C used the DS200PCCAG7AG in their Mark V rack. The standard DS200PCCAG7A boards were experiencing thermal shutdowns during summer months; the “G” variant eliminated these issues.

• Outdoor enclosure with solar loading – A solar thermal plant in the southwestern US installed the DS200PCCAG7AG in a Mark V rack located in a partially shaded outdoor enclosure. The enhanced thermal design allowed operation at the site’s 54°C peak summer temperatures without triggering OTP.

• Densely populated rack with restricted airflow – An offshore platform with a fully populated Mark V rack (limited airflow due to cable management) used the DS200PCCAG7AG to provide 7A capacity while maintaining thermal margin. The enhanced heatsink prevented thermal derating that had occurred with standard boards.

• High-altitude hydroelectric station – A 3,500m elevation dam facility with reduced air density (and thus reduced cooling effectiveness) selected the DS200PCCAG7AG for its improved thermal performance, ensuring reliable operation despite the challenging cooling environment.

Comparison with Related Variants

Key Takeaway: The DS200PCCAG7AG is the thermally enhanced version of the 7A power converter, offering extended temperature operation for warm environments. It does not include conformal coating or diagnostics – those features are only available on the ACB variants. For most applications, the DS200PCCAG2A is preferred due to better availability, while the “G” variant should be reserved for installations with specific thermal challenges.

Selection Suggestions

1. Calculate your +5V load – Select the DS200PCCAG7AG if the total is between 5A and 7A continuous and you have thermal concerns.

2. Assess ambient temperature and cooling – Choose the DS200PCCAG7AG if:

   • Ambient temperature regularly exceeds +45°C

   • Rack airflow is restricted (below 85 CFM)

   • You have experienced thermal shutdowns with standard boards

   • The installation is at high altitude (reduced air density)

   • The rack is located in a partially conditioned or unconditioned space

3. Consider the newer DS200PCCAG2A – For most applications, the DS200PCCAG2A is more available and cost-effective. Only select the “G” variant if thermal concerns are the primary driver.

4. Assess environmental conditions – The DS200PCCAG7AG has no conformal coating. For harsh environments with moisture or chemicals, you must choose the coated 7A ACB variant (DS200PCCAG7ACB or DS200PCCAG2ACB).

5. Verify physical fit – The larger heatsink on the DS200PCCAG7AG may extend slightly higher than standard boards. Ensure the rack’s top clearance is sufficient (typically >10mm above the board).

6. Evaluate if thermal issue can be solved otherwise – Before purchasing the specialized “G” variant, consider whether upgrading rack cooling (adding fans, improving airflow) could solve the thermal problem at lower cost.

7. Procurement – The DS200PCCAG7AG is very rare. Only purchase from suppliers providing:

   • Thermal performance verification (temperature rise data)

   • Full-load burn-in at elevated ambient temperature

   • Functional test report
     Lead times: 12-16 weeks.

8. Stock spares – Maintain at least one on-site spare due to extended lead times.

Important Precautions

• Power down completely – De-energize rack; wait 5 minutes for capacitor discharge. Hot-swapping not supported.

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

• AC input only – Do not apply DC voltage.

• Overtemperature reset – Red FAULT with OTP requires 15-minute cool-down, then manual power cycle. The “G” variant has higher thermal capacity but can still overheat if cooling fails.

• Cooling requirements – 85 CFM minimum. The DS200PCCAG7AG dissipates the same 45W as the standard 7A board; the enhanced heatsink provides better heat transfer but does not eliminate the need for airflow.

• Fan replacement – Replace 40mm fan every 4 years. The fan is the most likely failure point in warm environments.

• Cleaning – Use compressed air only (max 50 PSI, 30 cm distance). Pay particular attention to the heatsink fins – dust accumulation reduces thermal performance.

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

Final Expert Recommendation

The DS200PCCAG7AG is a specialized 7A power converter designed for installations with elevated ambient temperatures or marginal cooling. Its enhanced thermal design – featuring a larger heatsink, improved thermal interface material, and optimized airflow channels – extends the maximum operating temperature to +55°C and provides more graceful thermal derating compared to standard 7A boards.

Select the DS200PCCAG7AG when:

• Your +5V load is between 5A and 7A

• Ambient temperature regularly exceeds +45°C

• Rack airflow is restricted (below 85 CFM)

• You have experienced thermal shutdowns with standard boards

• You have confirmed that upgrading cooling is not feasible

However, consider these alternatives:

• Improve rack cooling – Adding or upgrading fans is often more cost-effective than sourcing the rare “G” variant.

• DS200PCCAG2A – For most applications, the newer 7A board is more available and cost-effective.

• Reduce load – If possible, reduce +5V load to fit within the 5A coated boards or lower-capacity options.

• Harsh environments – If you need conformal coating, the DS200PCCAG7ACB or DS200PCCAG2ACB are the appropriate choices (though they lack thermal enhancements).

The DS200PCCAG7AG does not include conformal coating or diagnostics – it is purely a thermal enhancement of the base 7A board. For facilities requiring both thermal performance and environmental protection, you would need to combine external measures (e.g., additional cooling, sealed enclosures) with the coated ACB variants.

When sourcing the DS200PCCAG7AG, ensure thermal performance verification is provided. With proper installation and cooling, this board will provide reliable 7A power in warm environments where standard boards would struggle. For standard indoor applications without thermal challenges, the DS200PCCAG2A or DS200PCCAG7A are more cost-effective and readily available.
