GE IS200EPSMG1ABB

GE IS200EPSMG1ABB is an exciter power supply module specifically designed for the GE Mark VI IS200 series control systems. It is suitable for large-scale industrial installations such as power plants, steel mills, coal-fired power stations, and ships. The module provides a stable 24V DC power supply (or multiple outputs of +5V, ±15V, +24V) for the system. It is equipped with multiple protections including overcurrent, overvoltage, and short circuit protection to ensure reliable operation of the control system in harsh environments.

• Dimensions: About 100mm × 50mm × 30mm; Weight: About 200g ~ 0.75kg
• Installation Method: DIN rail or screw mounting; compatible with Series 90-30/70 PLC backplanes

Product Features

• High Reliability: Industrial-grade design enables long-term operation under harsh conditions such as high temperature, low temperature, and vibration.
• Modular Structure: Adopts standardized plug-in modules for easy quick replacement and expansion.
• Multiple Protections: Built-in overvoltage, overcurrent, short circuit, and thermal protection to prevent equipment damage caused by abnormalities.
• High Efficiency: Power conversion efficiency up to 93% reduces energy consumption and heat dissipation.
• Wide Input Range: Compatible with 85 ~ 264VAC or 110 ~ 370VDC, adapting to different power grid environments.
• Rich Communication Interfaces: Supports multiple industrial communication protocols such as Ethernet and serial, facilitating integration into DCS/PLC systems.

Structure and Composition

• Front Panel: Equipped with seven indicator lights (P5, P15, N15, P24A, P24B, N24B, P70) and the GE logo for real-time monitoring of power supply status.
• Internal Core: Includes transformer, main inductor (Bicron B9309 0912), secondary inductor, power transistor (with heat sink), and multiple sets of radiators.
• Filtering and Energy Storage: Uses high-voltage electrolytic capacitors, axial electrolytic capacitors, metal film resistors and other components to achieve voltage smoothing and noise suppression.
• Protection Components: Nine fuses, multiple overvoltage/overcurrent detection circuits, and test points (TP) are installed on the board.
• Connectors: Provides backplane connectors and communication ports for easy connection to upper computers or fieldbuses.

Typical Application Fields

• Power Plants: Supplies power to excitation control systems (EX2100, Mark VI) to ensure voltage regulation and reactive power control of generator sets.
• Steel, Cement, Petrochemical: Provides reliable power supply in PLC/DCS of large-scale production lines to support process automation.
• Ships and Offshore Platforms: Suitable for power supply needs of offshore power generation and power systems.
• Other Industrial Automation: Scenarios requiring high-reliability power supply such as mining, papermaking, and shipbuilding.

Installation and Maintenance Guidelines

• Installation: It is recommended to use DIN rail fixing or screw fixing. Ensure the module is placed horizontally and sufficient heat dissipation space is reserved. Follow IEC 60364 standards when connecting power cables to ensure correct phase sequence.
• Wiring: Use cables that meet the rated current on the input side. Select appropriate terminals or junction boxes on the output side according to load requirements.
• Commissioning: After power-on, check the front panel indicator lights. Use a handheld multimeter or system diagnostic software to verify that the output voltage and current are within the specified range.
• Daily Inspection: Regularly check if the heat sink is dusty, if the fan (if any) is operating normally; check if the fuse is blown, and replace it with a fuse of the same specification if necessary.
• Fault Diagnosis: Use the TP test points on the board or the remote diagnostic function of the system to quickly locate overvoltage, overcurrent, or short circuit faults.
• Replacement: The modular design allows replacement by simply pulling out the old module, inserting the new module, then powering on again and verifying.
