4. Overview

The SANUPS E11A is a stationary-type uninterruptible power supply designed to provide

high-quality, stable AC power to critical equipment that requires continuous,

uninterrupted power.

The UPS is comprised of rectifier, charger, inverter, battery, and utility power transfer

(bypass) circuits. In the event of failure of the AC utility power source, AC output to the

load is sustained by the inverter converting DC power from the batteries. When the utility

power recovers, inverter operation continues while the batteries are recharged. The UPS

is therefore able to supply completely uninterrupted AC power to connected loads without

even momentary power loss.
