The ES22 series is an advanced online-interactive uninterruptible power system that produces pure sine wave power; Unlike traditional UPS, the series provides very short transfer when blackouts occur, and zero transfer from AC mode to battery mode and vice versa.The series voltage regulation is similar to an online UPS; however, the series provides greater than 98% efficiency under normal power conditions. Two charging modes are provided: fast charge and trickle charge, to keep the batteries in top condition.
