531X303MCPARG1 and F31X303MCPAPG1 are industrial-grade AC power boards of the GE 531X series. They are designed and manufactured by GE Boards & Turbine Control, and their core function is to provide stable AC-DC conversion and power supply support for GE legacy (old) general-purpose drive systems (such as DC-300 drives). Although the compatible systems are gradually becoming obsolete, their high flexibility and durability still make them serve as key spare parts in scenarios like industrial automation and motor control, ensuring the continuous operation of old equipment.

Electrical Performance Parameters

Input Voltage: The mainstream specification is 380-525VAC, applicable to industrial high-voltage scenarios. The compatible specification is 110-240VAC, suitable for global universal scenarios.
Output Parameter: The output voltage is 24VDC, providing stable DC output. The output current includes two specifications: 30A (mainstream) and 10A (compatible). The rated power is 720W, calculated as 24VDC multiplied by 30A.
Conversion Efficiency: It exceeds 90%, which can reduce power loss and lower operating costs in industrial scenarios.
Protection Function: It integrates overcurrent protection, overvoltage protection and undervoltage protection. Equipped with Metal Oxide Varistors (MOV), it can respond to power anomalies and protect downstream equipment.

Application Fields

• Maintenance of Old Industrial Drive Systems: It provides spare part support for legacy general-purpose drive systems such as GE DC-300, extending the equipment service life and avoiding system obsolescence caused by power supply failures.
• Motor Control Scenarios: It supplies power to industrial motor controllers with a rated current of ≤30A, and is compatible with equipment like machine tools and production line conveyor motors.
• Industrial Automation Control Systems: Serving as an auxiliary power module, it provides stable DC power for signal acquisition modules and actuators in industrial automation systems.
• Energy Management and Building Automation: It is compatible with power conversion units of energy management systems and fan/pump control modules in building automation, ensuring low failure rate operation of equipment.
