Product Description

The Bosch DM 45K 9101-D is a three-phase module with compact mechanics and 45 Amps maximum current rating at 2 kilohertz switching frequency. Three phase modules are designed by Bosch for operating linear, synchronous and asynchronous motors from the SF, SR and DU product lines. The DM 45K 9101-D is part of Bosch ServoDyn-D inverter systems. As the module is specially designed for industrial applications, therefore Bosch recommends that the module should not be connected to low voltage, medium voltage or high voltage public power grids. Rated DC link voltage for the module is 670 Volts DC regulated / 715 Volts DC un-regulated. Under overload conditions, the maximum module current varies from 47.5 Amps at 4 kilohertz switching frequency and 45 degrees Celsius ambient temperature to 35 Amps at 8 kilohertz switching frequency.

Under continuous current conditions, the rated module current varies from 23.5 Amps at 4 kilohertz switching frequency and 45 degree Celsius ambient temperature to 16.5 Amps at 8 kilohertz switching frequency. The DM 45K 9101-D includes standard encoder interface, and both CANopen and CANrho interfaces. The current demand of the module from the 24 Volts power supply is 1.4 Amps. The maximum rated power loss is 205 Watts. Weight of the DM 45K 9101-D is 6.7 kilograms and the width of the module is 75 millimeters. The DM 45K 9101-D is an air cooled module and requires 0 to 45 degrees Celsius ambient temperature for operation as per rated values. Housing of the DM 45K 9101-D has IP20 protection rating and should be mounted in IP54 rated cabinet. Installation of the module is recommended for elevations not exceeding 1000 meters above sea level. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
