Energy Meter

Simple kWh parameter monitoring can be achieved  with the WL4000 or WC4000 series. The meter offers site selectivity of kWh or kVAh in addition to site selectivity for kWh or kVA or W or PF thus making it easier for inventory management.

Parameters: Site selectable kWh / kVA / PF / W, Old energy
