The VRM protects equipment from electrical surges and voltage disturbances by utilizing safety thermal fusing and gas discharge tube surge protection technology. This unit monitors line voltage to the equipment based on the voltage parameters selected. Select the minimum low voltage and maximum high voltage and the VRM will break power to the equipment when either are exceeded. Adjustable voltage cutoff range 85 VAC to 300 VAC. The unit stores up to 300 fault events allowing determination of power input over periods. Unit automatically restores power upon resumption of power within the selected range. Power reset time is adjustable from 1 to 10 minutes.The RSH-50 VRMDC KIT (# 96424) combines the VRM60A, the RSH-50 and a 60 amp disconnect in a NEMA 3R enclosure.
