1.1 INTRODUCTION
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 exceeded.
Current value is processed to calculate the RMS amplitude and the total harmonic
distortion THD: when a maximum overload and current distortion threshold is exceeded
an alarm output is generated.
Temperature value, transduced by means of an internal 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 96x96mm) and low cost make MCP4 ideal to use in all industrial and civil
electrical plants.
