Blocksize Power Modules (PM240-2)
Power Modules are designed for single drives which are not capable of regenerating energy
to the 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
● Power Modules PM240-2 FSD and FSE have integrated DC link reactors and therefore
do not need a line reactor.
The FSA to FSE Power Modules cover the power range from 0.55 kW to 55 kW and are
available in versions with and without a line 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 unit with external air cooling (only frame sizes FSA - FSC)
