SINAMICS G120 Power Module PM 250 unfiltered, capable of regenerative feedback 3AC380-480V+10/-10% 47-63Hz, high overload performance: 55kW at 200% 3S, 150% 57S, 100% 240S, ambient temperature 0 to +50°C, low overload performance: 75kW at 150% 3S, 110% 57S, 100% 240S, ambient temperature 0 to +40°C 634x 350x 316 (HxWxD), FSF, protection class IP20 without Control Unit and BOP Power Module SINAMICS Power Module PM250, protection class IP20 for the modular frequency converter SINAMICS G120. The power modules are suitable for a wide range of applications in general mechanical engineering. Any braking energy that occurs is fed directly back into the grid (four-quadrant applications - no brake chopper required). The PM250 Power Module contains a technology that is unique worldwide, Efficient Infeed Technology. The regenerative capability achieved with this means that energy is fed back into the grid in generator mode (electronic braking) and is not destroyed in a braking resistor, which saves space in the control cabinet. The complex design of the braking resistor and the associated wiring are therefore no longer necessary, and the heat generated in the control cabinet is reduced. The innovative circuit technology also ensures fewer harmonics in the grid, and there is no need to use an optional grid choke at the grid input. This saves space and effort during project planning and procurement. The permissible cable lengths between the converter and the motor are limited. Output chokes can be connected to achieve longer cable lengths. The PM250 Power Module is also suitable for use in safety-related applications. In conjunction with a fail-safe control unit, the drive becomes a Safety Integrated Drive. The PM250 power modules are available in a three-phase voltage range between 380 V and 480 V and in sizes FSC to FSF. The sizes FSD to FSF are available both with and without an integrated Class A line filter. For the FSC size with an integrated Class A line filter, there is an additional base filter to achieve Class B. The PM250 power modules with an integrated Class A line filter are suitable for connection to TN networks, those without an integrated line filter are suitable for connection to grounded TN/TT and ungrounded IT networks. Shield plates and shield connection sets are available for EMC-compliant wiring of the control units and power modules. SINAMICS - simply my drive.
