ABB 07 NG 68 R1 Power Supply for Procontic Systems

The ABB 07 NG 68 R1 provides regulated DC power to Procontic controller racks. You can mount this unit directly into the dedicated power slot. It converts 115 V AC or 230 V AC into stable 24 V DC. This power supply supports all connected I/O and CPU modules reliably.

Technical Specifications and Hardware Configuration

This power supply module measures 130 mm in height. Its width reaches 65 mm, and the depth equals 110 mm. The ABB 07 NG 68 R1 weighs approximately 0.85 kilograms. A single internal PCB carries all rectification, filtering, and regulation circuits. The module contains two large electrolytic capacitors for energy storage. These capacitors provide 20 milliseconds of hold-up time during input dips. One 3-pin terminal block accepts AC input wiring. A dedicated 5-pin connector delivers DC output to the backplane.

Electrical Ratings and Performance Characteristics

The ABB 07 NG 68 R1 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 a nominal output of 24 V DC at 3.6 A continuously. Output ripple stays below 50 mV peak-to-peak at full load. Efficiency reaches 82 percent under typical operating conditions. Consequently, this unit generates moderate heat inside the cabinet. Overvoltage protection clamps the output at 28 V DC maximum. Short-circuit protection shuts down the output during wiring faults.

Installation and Operational Guidelines

You must slide this module into the leftmost slot of the Procontic rack. Transitioning to wiring, use 1.5 mm² stranded wire for the AC terminals. A green front LED indicates normal output voltage presence. The module requires 40 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.
