1. General Information
Inverter type UNV-F (named UNV on next pages) are avail-
able for delivery with an output power of 1.2, 1.8, 2.5, 3.3
and 5.0kVA per module. To increase the system output
power several units can be operated in parallel.
Typical applications are:
-
AC power supply with input side battery buffering
-
Industrial modular UPS with input side rectifier and bat-

rectifier
Inverter UNV-F converts input side DC voltage to stable
sinewave output voltage.
Several frequencies are available for delivery
UNV-F are hot-plugable modules with rear side connectors.
Only the communication wire (CAN bus) is connected on the
front. The inverter is controlled and monitored by internal
microprocessor. All main functional parameters are adjust-
able with front side operating keys and are indicated with
digital displays. Due to the excellent overall efficiency (see
technical data) the unit has very compact dimensions (19 -
rack, 3HU), low weight and so a very high power density.
Due to the special input side regulation principle the ripple
voltage limit fulfils the standard of CCITT-A-filtering without
any additional filter elements.
To increase the reliability of the inverter it is designed to op-
erate together with static bypass switch UNB. The static by-
