The Conzerv "ELF" series of power meters is designed to offer maximum measurement capabilities in a minimum of panel space. Three basic models are offered, one for Volts, Amps, Frequency and two which offer combinations of Watts, Watthours, VAR, VARh, VA, VAh and PF. (See chart below for parameters offered by the different models.)
Applications for these meters include sub-metering of power consumption, stand-alone metering in custom panels, switchboards, switchgear, gensets, motor control centers and UPS systems. The ELF series offers outstanding quality, versatility, and functionality in a low cost, ultra-compact meter. Ideal for monitoring single circuits, the meters can keep track of power usage for individual departments or even individual machines. They can identify opportunities for demand control and check energy consumption patterns.
The low cost of these meters plus the high accuracy and simple installation, enables economical measurement of commercial and residential tenant space. It's simple and easy to integrate the ELF meters into existing energy management systems.
