ABB NRED-61-E Voltage Divider Module – ACS800 Overvoltage Protection – Tested

Product Overview

Original ABB NRED-61-E thick-film hybrid voltage divider and overvoltage protection module for ACS800 series drives. Functions as a series voltage limiter in 690V AC systems, protecting the APOW-01C power supply board from DC bus overvoltage conditions. Employs ceramic substrate thick-film hybrid technology integrating power resistors, MOSFETs, and Zener diodes for robust thermal stability and transient suppression. Used in ACS800 and ACS600XT series drive systems.
