Maximum control over three parameters: voltage, current and power
The ZUBR MF2 red multifunctional relay has a compact 2-module wide housing. Thanks to three digital screens, it simultaneously displays the value of voltage, current and power, which is very convenient when controlling all parameters at the same time. In standby mode, you can adjust the screen brightness. The ZUBR MF2 red relay has a wide functionality that combines: ZUBR CV2 functions, ZUBR MF current and power control, as well as the possibility of in-depth settings for current limits.
High voltage and current measurement accuracy thanks to TrueRMS algorithm
TrueRMS reduces the effect of line noise on voltage, current, and power measurement accuracy when the voltage waveform is other than a sine wave. Thanks to this algorithm, the relay will turn off the load before the power surge negatively affects the connected devices.
Professional load shedding model
You can activate the professional turn-off delay model to reduce the number of trips of modern equipment that operates stably under certain supply voltage fluctuations. Thus, the use of ProModel allows you not to turn off the equipment in case of voltage deviations that are safe in magnitude and duration.
ProModel is based on the ITIC (CBEMA) Curve.
