The IS220PPROS1B is a Redundant Power Supply Module from GE's Mark VIe series control systems. It is primarily designed to provide a highly reliable redundant power supply solution for large industrial control systems (such as turbines and generator sets), ensuring continuous operation even when the main power supply fails. Below is its detailed information:
- Module Type: Redundant power supply module, a key power component of the Mark VIe system, supporting dual-path redundant configuration.
- Input Power: Typically supports AC input with a standard specification of 115/230VAC (50/60Hz), adaptable to grid standards in different regions.
- Output Power: Provides stable DC output, with a standard output of 24VDC. The output current capacity can reach several amperes depending on system configuration (specific parameters should refer to system requirements), meeting the power supply needs of downstream control modules.
- Redundancy Mechanism: Adopts N+1 redundancy design, supporting parallel operation of two modules. When one module fails, the other can seamlessly take over the power supply to ensure uninterrupted output.
- Protection Functions: Equipped with multiple protection functions such as overcurrent protection, short-circuit protection, overvoltage protection, and overtemperature protection, which can quickly respond to power abnormalities and protect downstream equipment.
- Operating Environment:
- Operating temperature: 0°C to 55°C
- Storage temperature: -40°C to 85°C
- Humidity: 5% to 95% RH (non-condensing)
- EMI resistance: Complies with industrial-grade EMC standards, suitable for high-interference environments such as power plants and heavy industry.
- High-Reliability Redundant Design: The dual-module redundant architecture eliminates the risk of single-point failures, ensuring the control system remains operational even when a power module fails, meeting the high availability requirements of critical industrial scenarios.
- Seamless Switching Capability: The switching time between primary and backup power modules is extremely short (usually in milliseconds). The output voltage remains stable during switching, without causing power supply fluctuations to downstream control modules.
- Real-Time Status Monitoring: Equipped with LED indicators and diagnostic interfaces, it can display real-time power input/output status, module operation mode (primary/backup), fault alarms, etc., facilitating maintenance personnel to quickly determine system status.
- Hot-Swappable Support: Supports online hot-swap replacement, allowing faulty modules to be replaced without shutting down the system, minimizing maintenance downtime.
- Efficient Power Conversion: Adopts high-efficiency power conversion technology with conversion efficiency typically exceeding 90%, reducing energy consumption and heat generation, suitable for long-term continuous operation.
- Main power supply for Mark VIe control systems of large rotating machinery such as gas turbines and steam turbines.
- Control and protection systems for generator sets in thermal power plants, nuclear power plants, and combined cycle power plants.
- Control systems of large industrial equipment with extremely high requirements for power supply reliability in petrochemical, metallurgical, and other industries.
- Serving as a core power component to provide continuous power for CPU modules, I/O modules, communication modules, etc., in the Mark VIe system.
- Exclusively applicable to the GE Mark VIe control system, requiring compatibility with the same series of power distribution modules (e.g., IS220PPDAH1B), backplanes, and control modules.
- Supports uploading power status data to the main controller via the internal system communication bus, and can be integrated into plant DCS or SCADA systems for remote monitoring.
- Needs to be configured via GE ControlST software to ensure that the redundancy logic matches the overall power supply scheme of the system.
With its redundant design and high reliability, this module has become a core component ensuring continuous power supply in critical industrial control systems, widely used in energy, power, and other industries sensitive to downtime losses.
