Electrocorder EC-7VAR

The Electrocorder EC-7VAR-RS Dual current range energy recorder from Acksen is used by electrical contractors, power distribution companies, facilities management, electrical or site-services and maintenance engineers 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.

Extensively 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.

Setting up the Electrocorder EC-7VAR is easy, suitable for non-technical staff. Using the supplied (free) Windows software, Electrosoft; input the location details for the logging and choose the logging period. Electrosoft will print the necessary dispatch/return documentation including user instructions. All data is included in a database of dispatches and returns, allowing you to track the location of multiple loggers.

The advantage of the Electrocorder products over most others is that the data logger constantly samples information (recording the Min, Max and Average) over the set period, many other products only take 'snap shots' of what is going on and can miss 99.9% of the data that is critical to your analysis.
