EC-7VAR Three Phase Voltage, Current & Power Factor Data Logger


The EC-7VAR PQA is used by electrical contractors, power distribution companies, facilities management, electrical or site-services and maintenance engineers. It is used to monitor power (kW)/energy (kWh) usage, check voltage and current variations helping them to diagnose any related issues, or to gather data perhaps to make representations to their power supplier.

Widely used for UPS sizing and monitoring and standby generator sizing and monitoring. As the product records both voltage and current, users can determine if low voltage is related to high current demands on site, or if the low voltage is being supplied to the site.
