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 the new PM240-2 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.
Among the unique, 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, thereby reducing both the noise generated and the power required when in use.
The PM240-2 power modules are suitable for use with general-purpose and servo-drive styles. Options on these PM240-2 power modules include braking resistors, input reactors and output reactors.
