Models in the WM Series are rated from 800VA/600W to 4000VA/3000W (230VAC output) and up to 3200VA/2400W (115VAC output). DC to AC isolation is standard. All models are protected against over current and over charging and incorporate CPU controlled thermal protection. Every unit has a thermally controlled cooling fan. Smart monitoring and warning for battery failure or open circuit battery is included and a fully functional LED or LCD display provides users with visual systems information.
