More Information
The voltage relays MK 9064N and MH 9064 of the varimeter family pro-
vide a solution for an optimised monitoring of the function of an electrical
device. Single-phase AC and also DC can be measured, undervoltage,
overvoltage and voltage window are monitored and the measured value
is displayed on the front.
