MeloAuto-Trusted PLC & DCS Parts Supplier
The GE 2180J28-001 provides regulated DC power to GE automation control racks. You can install this unit into the dedicated power slot of Series One or Series Three PLCs. It converts 115 V AC or 230 V AC into stable 5 V DC and 24 V DC outputs. This unit supports CPUs, I/O modules, and communication cards reliably.
Technical Specifications and Hardware Configuration
This power supply measures 254 mm in height. Its width reaches 76 mm, and the depth equals 152 mm. The GE 2180J28-001 weighs approximately 1.6 kilograms. A single internal PCB carries all rectification, filtering, and regulation circuits. The module contains four electrolytic capacitors for bulk energy storage. These capacitors provide 35 milliseconds of hold-up time during input dips. One 4-pin screw terminal block accepts AC input wiring. A dedicated 8-pin connector delivers DC outputs to the backplane.

Electrical Ratings and Performance Characteristics
The GE 2180J28-001 accepts input voltages from 85 V AC to 264 V AC. It operates at line frequencies of 47 Hz to 63 Hz automatically. This module delivers 5 V DC at 8 A for the backplane logic. It also provides 24 V DC at 2 A for output modules and relays. Output ripple stays below 40 mV peak-to-peak at full load. Efficiency reaches 80 percent under typical operating conditions. Consequently, this unit powers complete Series One and Three configurations. Overvoltage protection clamps both outputs at safe levels. Short-circuit protection shuts down individual outputs during wiring faults.
Installation and Operational Guidelines
You must slide this unit into the leftmost slot of the PLC rack. Transitioning to wiring, use 1.5 mm² stranded wire for the AC terminals. A green front LED indicates normal output voltage presence. The unit requires 50 mm of free space above and below for airflow. For safety, disconnect mains power before removing the unit. The operating temperature range sits between 0°C and 55°C reliably.
