FAQ

The RM35TF30 allows for the adjustment of the undervoltage threshold (from -2% to -20% of the nominal supply voltage) and the overvoltage threshold (from +2% to +20%). It also features an adjustable time delay to prevent nuisance tripping from momentary fluctuations.

Yes, the RM35TF30 is designed to monitor a voltage window. It will trigger if the voltage goes below the set undervoltage threshold or exceeds the set overvoltage threshold, providing comprehensive protection.

While it can be used, caution is advised. The non-sinusoidal output of some VFDs can cause inaccurate readings or nuisance tripping. It is recommended to install the relay on the line side (input) of the VFD or consult the VFD's documentation for compatibility with monitoring relays.
