Open the catalog to page 1

Multi-functional monitoring relay for undervoltage, overvoltage and frequency monitoring in AC/DC systems without separate supply voltage Product description The voltage monitor VME421H monitors AC/DC systems in the frequency range of DC/15…460 Hz for undervoltage, overvoltage, underfrequency or overfrequency. Device variant -1 is suitable for the nominal voltage range Un = 9.6…150 V, device variant -2 for Un = 70…300 V. The supply voltage is taken from the nominal voltage being monitored Un. In order to meet the requirements of the applicable standards, customised parameter settings must...
