An instrument that monitors the voltage and protects electrical equipment in industrial, commercial, and housing uses. By using the True-RMS* measuring method it monitors voltage and protects monophasic loads against over and/or under voltage. In addition, it has an automatic timer that waits 3 minutes before activating its output, which warrants equipment protection, such as compressors, requiring a minimum stop time.

_ *True-RMS: the real voltage value, considering the contribution generated by high-frequency noise in the network (harmonic distortion). The voltage can be measured precisely in any waveform through this method, whereas traditional methods only correctly measure when it has a perfect sinusoidal wave.
