MLT 10 - 120 kVA



Short description

On-Line UPS-system in double conversion technology according to IEC / EN 62040-3 (VFI-SS- 111) with sinus soidal output voltage in each operation mode, LCD display, RS232 interface, USB connection, alarm contacts, emergency stop function, 2 slots for communication cards, shutdown-software for Windows NT/2000/XP/2003/ Vista, Novell und Linux system software. Optionally up to 6 systems may be switched in parallel. The operation modes on-line, line-interactive, smart active or emergency supply (Standby) can be adjusted with the means of the display. Back-up time of the system can be increased by connecting additional external battery modules.
