• Strong Compatibility: Can be directly used in GE RX3i, GE Fanuc, and other PLC/PAC systems, supporting 24 VDC control signal input.

Structure and Composition

• Power Conversion Unit: Implements AC-DC and DC-DC conversion, providing multiple regulated outputs.
• Protection Circuit: Includes overvoltage, overcurrent, short circuit, and overtemperature detection modules.
• Interface Terminals: High-current terminals, low-voltage terminals, and signal input terminals, all using screw or quick snap-on connections.
• Heat Dissipation Structure: Metal housing combined with internal heat sinks ensures thermal management during long-term operation.

Typical Application Fields

• Industrial Automation: Power supply for PLCs, PACs, and CNC systems.
• Unit and Turbine Control: Provides regulated power supply for turbines and generator sets.
• Robotics and Motion Control: Power supply for drives and servo systems.
• Power Distribution and Monitoring: Auxiliary power supply for distribution cabinets and monitoring systems.
• Other Scenarios Requiring Low-Noise DC Power: Such as sensor arrays and communication modules.

Installation and Maintenance Guidelines

• Location Selection: Ensure the installation position has good ventilation, avoiding high temperature or strong magnetic field interference.
• Power Wiring: First confirm the input voltage range (90-132 VAC or 180-264 VAC), and use cables and terminals that meet specifications.
• Fixing Method: Adopt DIN rail or panel quick screw mounting to ensure the module is firmly fixed without shaking.
• Protection Function Check: Check if overvoltage, overcurrent, and short circuit protection work normally before power-on.
• Regular Inspection: Inspect terminal tightness, heat sink dust accumulation, and whether the housing has cracks or corrosion every 6-12 months.
• Replacement and Maintenance: If abnormal noise, overtemperature alarm, or unstable output occurs, first cut off the power to check the internal fuse or protection circuit, and replace the entire unit or corresponding sub-module if necessary.
