ABB 086407-502 Power Supply Module for AC 800M / 800xA DCS

Product Brief Description: ABB 086407-502 is a hot-swappable power supply module for ABB AC 800M controller (PM851, PM856, PM860, PM864, PM866) and System 800xA DCS platform. It provides regulated DC power for the controller CPU, backplane and I/O modules, supports parallel redundant configuration for critical process control systems. The universal wide-range AC/DC input design ensures stable power conversion and protection against overload, short-circuit and over-temperature faults. It is widely used as spare replacement part in power, chemical and oil & gas control cabinets.
