ABB 07 NG 82 R3 Procontic Power Supply for Controller Racks

The ABB 07 NG 82 R3 supplies stable DC power to Procontic controller systems. You can install this module into the dedicated power slot of any Procontic rack. It converts universal AC mains into regulated 24 V DC output. This unit supports CPUs, I/O modules, and communication interfaces reliably.

Technical Specifications and Hardware Configuration

This power supply module measures 130 mm in height. Its width reaches 85 mm, and the depth equals 110 mm. The ABB 07 NG 82 R3 weighs approximately 1.1 kilograms. A single internal PCB carries all rectification and regulation circuits. The module contains three electrolytic capacitors for bulk energy storage. These capacitors provide 30 milliseconds of hold-up time during power interruptions. One 3-pin screw terminal block accepts AC input wiring. A separate 6-pin connector delivers DC output to the backplane.

Electrical Ratings and Performance Characteristics

The ABB 07 NG 82 R3 accepts input voltages from 85 V AC to 264 V AC. It operates at line frequencies of 47 Hz to 63 Hz without adjustment. This module delivers a nominal output of 24 V DC at 5 A continuously. Output ripple stays below 30 mV peak-to-peak at full load. Efficiency reaches 85 percent under typical operating conditions. Consequently, this unit runs cooler than lower-rated models. Overvoltage protection clamps the output at 29 V DC maximum. Short-circuit and overload protection shut down the output safely.

Installation and Operational Guidelines

You must slide this module into the leftmost slot of the Procontic rack. Transitioning to wiring, use 1.5 mm² to 2.5 mm² stranded copper wire. A green front LED indicates normal output voltage presence. The module requires 50 mm of free space above and below for airflow. For safety, disconnect mains power and wait two minutes before servicing. The operating temperature range sits between -10°C and 55°C reliably.
