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
