The WM Series of uninterruptible power supplies announced by Powersolve are wall-mount units designed to provide back-up power for long periods. Rated from 800VA/600W to 4000VA/3000W, the WM Series accepts a very wide AC input range while providing a pure sine wave output for up to several hours or more.
These are line interactive UPS systems with a 3ms transfer time. They are both generator compatible and cold start capable and feature adjustable voltage transfer points and charging voltage.
WM Series units combine high power chargers with smart battery management enabling them to charge high capacity external lead acid batteries (up to 500AH) for longer hold-up times. The units provide adjustable charging currents for different batteries as well as intelligent, two-stage charge control. Powersolve can also provide units with an optional solar charger input.
The WM Series accepts a wide AC input voltage range of 140 to 310VAC for 230V models and 70 to 155VAC for the 115V version.
