The PROTECT 1.M has been designed for operating up to six 
UPS modules. Depending on the output power required, the 
unit is operated in normal mode with between one and six 
modules installed. These modules can easily be installed, 
removed or replaced under a very wide range of operating 
conditions. 
PROTECT 1.M uses a high-performance communication 
module to collect information from the individual UPS modules 
via the internal network within the unit and displays this 
information on an LC display. This greatly facilitates operation 
of the UPS.  
PROTECT 1.M protects your systems against numerous power 
supply problems such as mains failures, voltage and frequency 
fluctuations, under and overvoltage, voltage distortions, voltage 
harmonics, etc.

The UPS is connected between the public utility mains and the 
loads to be protected. 
The power sections of the UPS module rectifier convert the 
mains voltage to DC voltage for supplying the inverters. The 
circuit technology used (PFC) enables sinusoidal current 
consumption and therefore operation with little system
