Toronto Electricians and Electrical Contractors

Uninterruptible power supply (UPS) technology has changed quite a bit over the past several years, with newer devices offering far more intelligence and energy efficiency than previous generations. Electrical contractors charged with helping customers choose the right UPS for their various applications would do well to understand the various features and functions that UPSs now provide – so they can help customers choose wisely. Let’s start with energy efficiency. So-called “eco-mode” UPSs have been around for more than a decade, but only now are beginning to gain traction, thanks to some advancements in the technology.  The idea is to reduce the power loss involved in the double power conversion process – from AC to DC and back again – that’s involved in “cleaning” utility power. In eco-mode, UPSs bypass that process most of the time, until it detects a power quality issue. That technology never caught on in a big way because it took a few milliseconds for the conversion proces...
