Internal Design and Power Distribution

This power supply uses a switching converter design for high efficiency. A full-bridge rectifier converts AC to DC for the output rail. The ABB 07 NG 35 employs three filtering capacitors for energy storage. These capacitors provide 20 ms of hold-up time during short interruptions. The 24 V DC output powers I/O modules and field devices. Consequently, this unit delivers reliable power for Advant control systems.

Installation and Connection Guide

First, mount this power supply onto a standard 35 mm DIN rail securely. Next, connect your AC mains wires to the L, N, and PE input terminals. Then, wire your 24 V DC loads to the output terminals (+ and -). Use appropriate wire gauges for the 3.5 A output current. The module includes a green LED for output OK status. A red LED illuminates during fault conditions like overcurrent. This power supply works with ABB Advant controllers and S100 I/O systems. Always disconnect AC power before removing the module from the rail.
