Product Description

The DMA 004A 1101-D is a Bosch Rexroth three-phase module with backplane dynamics. It has a maximum current rating of 4 Amps at 2 kilohertz switching frequency. For maximum overload conditions at 4 kilohertz, the peak current is 5.6 Amps and the rated current is 2.7 Amps. For maximum continuous load conditions at 4 kilohertz, the peak current is 5.6 Amps and the rated current is 5.6 Amps. For maximum overload conditions at 8 kilohertz, the peak current is 5.6 Amps and the rated current is 1.7 Amps. For maximum continuous load conditions at 8 kilohertz, the peak current is 5.6 Amps and the rated current is 3.3 Amps. At 4 kilohertz the current derates by 0.15 Amps for every additional degree (Celsius) increase in temperature between 45 and 55 degrees Celsius.

At 8 kilohertz the current derates by 0.08 Amps for every additional degree (Celsius) increase in temperature between 45 and 55 degrees Celsius. The DMA 004A 1101-D comes with a SERCOS interface and a standard encoder. Features of the SERCOS interface include real-time processing, free combination of drives/controls of any manufacturer and fiber-optic interface. Weight and dimensions of the DMA 004A 1101-D are 7.3 kilograms and 517 x 50 x 288 millimeters respectively. Power demanded by the DMA 004A 1101-D from the 24 Volts power supply module on the inverter system is 1.0 Amps. The peak power loss of the DMA 004A 1101-D in the switch cabinet is 94.3 Watts. The DMA 004A 1101-D module is an air cooled device. Bosch recommends providing minimum 100 millimeters clearance around the mounted module. Protection rating of the DMA 004A 1101-D three-phase module is IP 20. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
