1 or 3-Phase Output from 200VA to 45kVA, switchmode Inverters
Series IT - Inverters with 1-phase output from 200 VA to 15 kVA Page 89
DC/AC Inverters
is a combination of a switch mode Inverter and a Transformer at the output. The
transformer provides the isolation between input and output and transforms
the voltage to the required level.
AC output DC input
Inverter Transformer
AC/AC Frequency Converters
is a combination of a switch mode Inverter with a rectifier at the input and
a Transformer at the output. The transformer provides the isolation between
input and output and transforms the voltage to the required level.
AC output AC input
Inverter Transformer
For lower input voltages the CI version is more compact than the IT version.
Series CI - Inverters with 1-phase output from 400 VA to 3.5 kVA Page 91
DC/AC Inverters
is a combination of a switch mode Converter and Inverter. The converter
provides the isolation between input and output and transforms the voltage to
the level needed by the inverter for supplying the specified AC output voltage.

3 x Inverter
3-phase
3 x Transformer
is a combination of 3 individual switch mode inverters with output transformers
synchronized for a symmetrical 3-phase output. The transformers provide the
isolation between input and output and transform the voltages to the required
levels.
Series SS from 800 VA to 10 kVA Page 97
Static Switches
The Static Switch has two inputs for load supply, a priority and a non-priority
input, and synchronizes the frequency of one supply to the other. Typically, but
not exclusively, supplied by Mains & an Inverter, there are 3 modes of operation:
1. Service mode Mains - mains is selected as the load provider.
2. Service mode Inverter - inverter is selected as the load provider.
3. Automated function with priority selection.

UPS Systems with Static Switch
provides uninterrupted AC power to a critical load by connecting the load to
AC supply 1 which can be the inverter output or to AC supply 2 which can
be the mains. Series U does not include the batteries. The batteries can be
specified and both, batteries and charger can be added to the system.
