The MCP4 device has been designed to protect the electrical panels and electrical plants, mainly the power factor regulation and filtering plants, by mean of continuous monitoring of line voltage, line current (amplitude and harmonics) and temperature.
The voltage value is compared with a threshold value programmable, giving an alarm when over.

Current value is processed to calculate the RMS amplitude and the total harmonic distortion THD: when a maximumshort-circuit and current distortion threshold is exceeded an alarm output is generated.

Temperature value, transduced by means of an internal or external probe, is monitored to activate cooling devices (fan, etc...) when a programmable pre-alarm threshold is exceeded and to produce an alarm if a programmable maximum value is exceeded.

All measurements and alarms are displayed on the front panel display. Working parameters setup is accomplished using 4 functional keys.

Small size (DIN 96x96 mm) and low cost make MCP4 ideal to use in all industrial and civil electrical plants.
