ABB 07 NG 63 R2 Power Supply | 24V 2.5A, 60W, 88% Efficiency

This power supply unit energizes ABB Procontic racks and modules. The ABB 07 NG 63 R2 converts AC mains voltage into stable DC power. You can mount this unit directly inside the control cabinet. Its reliable design supports continuous operation in industrial environments.

Physical Dimensions and Mounting Configuration

The ABB 07 NG 63 R2 measures 16.5 cm in overall width. Its total depth reaches 18.2 cm including terminal covers. This power supply weighs approximately 1.25 kg. A metal enclosure provides excellent heat dissipation and shielding. Four mounting screws secure the unit to a DIN rail or backplate.

Input and Output Specifications

This unit accepts 100 to 240V AC input voltage automatically. The ABB 07 NG 63 R2 delivers 24V DC at 2.5A continuously. Output power reaches 60W under normal operating conditions. Built‑in overload protection shuts down the unit during short circuits. Furthermore, the module resumes operation automatically after fault removal.

Energy Storage and Hold‑Up Performance

A large 470 µF capacitor stores energy for brief power interruptions. The ABB 07 NG 63 R2 provides 20 ms of hold‑up time at full load. This storage allows the CPU to complete critical operations safely. Consequently, system shutdowns occur gracefully rather than abruptly.

Protection Circuits and Diagnostic Features

Overload protection activates when output current exceeds 3.0A. Short circuit protection responds within 50 µs of fault detection. The green DC OK LED confirms proper output voltage presence. Therefore, maintenance personnel can verify power status at a glance.

Installation and Wiring Guidelines

Connect the AC input wires to the three‑pin terminal block. The ABB 07 NG 63 R2 accepts wire sizes from 0.5 to 2.5 mm². Route DC output wires separately from AC input cables. This separation reduces electrical noise on the 24V DC bus.
