Product Description:
The PR201 Power Monitor (for switchboard mounting type) can help energy saving, thus reducing cost, and also help diagnose electrical equipment. PR201 has the same barrel mounting as 4-1/2″ switchboard meter for easy replacement of existing meters. It measures electric energy (power) consumed by electrical equipment and displays the value as the integral power consumption. It also displays instantaneous power, voltage, current, power factor, etc. For optional output function, 4 to 20mA analog output for instantaneous power value or integrated pulse output is available. For optional communication function, RS485 or LON communication interface is available.
