Siemens: AC power modules

PM240-2 power modules are now available from Siemens, extending the use of the Sinamics G120 drives family; a significant change is the addition of 230V single- and three-phase line supply units featuring quick-connect pull-off terminals on the motor, line supply, and braking resistor connections; allowing unit to offer an even more simplified installation and maintenance.

In addition, these new power modules can be mounted side-by-side without derating. 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 and 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.
