Mini-EVR™ Operation




The Mini-EVR™ works automatically with no operator effort required. There is no scheduled maintenance, so it is virtually effort-free.

The standard Mini-EVR™ uses microprocessor-controlled tap switching technology like its big brother, the Sure-Volt™.  Rather than an isolation transformer, the Mini-EVR™ uses an autotransformer to reduce size, weight and provide a 99% efficiency.  Relative to a ferroresonant transformer, the Mini-EVR™:

Requires no oversizing for inrush current
Creates minimal load on air conditioning
Has near-silent operation
Can readily be installed in weatherproof or hazardous location enclosure
Is less than half the weight

Installation of the Mini-EVR™ is simple.  It arrives completely assembled, ready to wall mount like a typical panel.  The is no assembly, no programming, nothing to adjust, no training needed - essentially "plug and play".
