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.

Fig.: Component diagram of an individual PROTECT 1.040 UPS module

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
