Description
This UPS is either rack mountable or a free standing tower unit. it has a PFC (power factor correction) of 0.9pfc (dependant on input volatage). As an online UPS this offers protection from power surges and spikes as the current is first flowed through the batteries and then to the connected equipment thus offering a higher level of protection than standard line interactive UPS’s. Greater back up time can be achieved with the use of external battery packs.
- Ensures highest reliability and availability with double conversion and true on-line technology
- Enables integration with wide variety of site environments with super compact tower/rack convertible design
- Offers high energy savings with near unity input power factor design
- Suits various utility requirements with wide input voltage tolerance (120~280V dependant on load)
- Provides easy reading of major parameters and status on LCD display
- Provide powerful charging capabilities to re-charge internal battery to 90% in 3 hours
- Lets you monitor from PC via RS232 communications interface
- Features customer options slot for SNMP, AS400, volt-free interface
- Allows quick replacement with easy swappable battery
- Offers extra long back-up time with various external charger options (up to 3000W)
- Makes maintenance easy without interrupting the loads with optional external maintenance bypass switch
