GE DS200DSPCH1

Technical Parameters & Specifications

Core Advantages & Key Features

• Integrated Power Supply and Battery Charger – The DS200DSPCH1 consolidates system power regulation and battery backup charging into a single board, eliminating the need for separate charger modules and reducing rack space requirements.

• Temperature-Compensated Charging – The DS200DSPCH1 includes a temperature sensor input that adjusts charging voltage based on battery temperature, extending battery life and preventing overcharging in hot environments or undercharging in cold conditions.

• Automatic Changeover – In the event of primary power loss, the DS200DSPCH1 automatically switches to battery power without interruption, ensuring continuous operation of the Mark V control system and critical safety functions.

• Dual Input Capability – The board accepts either 120 VAC or 125 VDC primary input, providing flexibility for various site power configurations.

• Multiple Regulated Outputs – Supplies +5V (logic), ±15V (analog), and +24V (field devices) to the control rack and connected instruments.

• Battery Health Monitoring – The DS200DSPCH1 continuously monitors battery voltage, charge current, and internal resistance, providing diagnostic information to the main processor for preventive maintenance alerts.

• Diagnostic LEDs – Onboard indicators show primary power status, battery charge status, output voltage health, and fault conditions for quick troubleshooting.

• Protection Features – Includes overcurrent protection, reverse polarity protection, over-temperature shutdown, and battery deep-discharge prevention.

• Robust Environmental Protection – Conformal coating and gold-plated edge connectors ensure reliable operation in humid, dusty, or corrosive environments.

• Plug-and-Play Compatibility – The DS200DSPCH1 integrates seamlessly with all Mark V main processors, including DS200CPCAG1A, and works alongside driver boards such as DS200DPCAG1ADC and DS200DPCAG1ADB without additional interface hardware.

Typical Applications

• Gas Turbine Control Systems – Provides uninterruptible power for fuel valve control, inlet guide vane actuators, and combustion monitoring during momentary power sags or brief outages.

• Steam Turbine Emergency Systems – Ensures continuous power for overspeed protection circuitry, trip solenoids, and critical transmitters during primary power loss.

• Compressor Station Control – Maintains power for anti-surge control algorithms and valve positioning during grid disturbances.

• Uninterruptible Control Panels – Provides backup power for systems requiring continuous operation, including black-start capable installations.

• Remote or Unattended Facilities – Ensures safe shutdown and restart sequences during power interruptions at offshore platforms or pipeline stations.

Field Example: An Asian LNG terminal experienced recurring nuisance trips due to momentary grid voltage dips. Installation of DS200DSPCH1 boards with properly sized batteries eliminated 95% of these events, maintaining compressor station operation during power disturbances.

Selection Guidelines & Precautions

• Verify Input Voltage Configuration – The DS200DSPCH1 can be configured for either 120 VAC or 125 VDC primary input via onboard jumpers. Ensure the correct setting is applied before installation to prevent damage. Refer to GE manual GEK-119615 for configuration details.

• Select Appropriate Battery Type – The DS200DSPCH1 supports sealed (VRLA) or flooded lead-acid batteries. Verify that the selected battery type matches the board’s charging profile. Use GE-recommended battery sizes (typically 7–12 Ah) as specified in the installation manual.

• Check Battery Placement – Locate batteries in a well-ventilated area away from heat sources. Temperature compensation requires the temperature sensor to be mounted on or near the battery bank for accurate measurement.

• Calculate Backup Time – Determine the required backup duration based on site power reliability. The DS200DSPCH1 can maintain system operation for 15–60 minutes depending on battery capacity and system load.

• Verify System Load – Calculate total current draw from all connected boards and field devices to ensure the DS200DSPCH1 can supply adequate power during both normal and battery operation.

• Grounding Practices – Follow GE recommended grounding practices to ensure proper operation of the charger and protection circuits.

• Firmware Compatibility – The DS200DSPCH1 is compatible with all Mark V main processor firmware versions. No special firmware updates are required for basic charging functionality. Battery health monitoring data is available via the backplane and can be read by DS200CPCAG1A processors.

• Spare Parts Strategy – The DS200DSPCH1 is the standard power supply/charger board for Mark V systems. Maintain at least one unit as a cold spare, and periodically test backup batteries (every 6–12 months) to ensure capacity meets requirements.

• Battery Replacement Schedule – Lead-acid batteries typically require replacement every 3–5 years. Monitor battery health diagnostics from the DS200DSPCH1 to plan replacements proactively.

Summary

The DS200DSPCH1 is a specialized power supply and battery charger board for GE Mark V systems, providing regulated outputs (+5V, ±15V, +24V) and intelligent temperature-compensated battery charging with automatic changeover in a single 6U board. It ensures uninterrupted system operation during primary power interruptions, with battery health monitoring for preventive maintenance. The board integrates seamlessly with DS200CPCAG1A processors and works alongside driver boards including DS200DPCAG1ADC and DS200DPCAG1ADB. Selection requires attention to input voltage configuration, battery type compatibility, backup duration calculations, system load verification, and proper battery placement for temperature-compensated charging to ensure reliable uninterrupted operation in critical turbine and compressor control applications.
