Introduction
The Rittal PMC UPS 6kVA Series is an uninterruptible power
supply incorporating double-converter technology. It provides perfect
protection specifically for Novell, Windows NT and UNIX servers.
The double-converter principle eliminates all mains power
disturbances. A rectifier converts the alternating current from the
socket outlet to direct current. This direct current charges the batteries
and powers the inverter. On the basis of this DC voltage, the inverter
generates a sinusoidal AC voltage which permanently supplies the
loads.
Computers and periphery are thus powered entirely
independently of the mains voltage. In the event of power failure, the
maintenance-free batteries power the inverter. This means an end to
the switchover times from mains to battery operation which cannot be
avoided on other systems.
