Description of PM240-2

A Power Module is a power unit (frequency converter) that provides the power supply for the
connected motor. It must be connected with a Control Unit, in which its open-loop and
closed-loop control functions are saved.
Power Modules are designed for single-motor drives without energy recovery into the line
supply. Generated energy produced during braking is converted to heat in braking resistors.
Power Modules of the Blocksize format contain:
● Output inverter for the supply of a motor
● Braking chopper for (external) braking resistor
● 24 VDC / 1 A power supply
● Fan to cool the power semiconductors
● PM240-2 Power Modules FSD to FSG have integrated DC link reactors and therefore do
not need a line reactor.
The FSA to FSF Power Modules cover the power range from 0.55 kW to 132 kW and are
available in versions with and without a line filter.
Power Modules FSG have a power range from 160 kW up to 250 kW. They are equipped
with a line filter:
● 400 V devices: either C2 or C3 filter
● 690 V devices: C3 filter
The PM240-2 Power Modules are designed for installation in the cabinet and in the following
cooling variants:
● Built-in unit with internal air cooling
● Push-through device with external air cooling (exception, FSG)
