Siemens has introduced a new line of PM240-2 power modules; this extends the use of the popular Sinamics G120 drives family.
A significant change in the new modules is the addition of 230V single- and three-phase line supply units. New features simplifying installation and maintenance include:
- Quick-connect pull-off terminals on the motor
- Line supply and breaking resistor connections
All versions of the new PM240-2 power modules are rated IP20. However, an optional push-through version is available allowing the heat sink to extend out the backside of the cabinet. The seal for the push-through heat sink will maintain an enclosure rating of IP55 (NEMA 12). As a result, the new PM240-2 power modules will reduce the overall required cabinet size and cabinet cooling requirements.
Among the new features of the PM240-2 power modules is the variable speed cooling fan, controllable to run based upon actual conditions vs. simple on/off operation. This reduces both the noise generated and power required when in use.
PM240-2 power modules are suitable for use with general-purpose and servo-drive styles. Options include braking resistors, input reactors and output reactors.
