DKCXX.3-040-7-FW

DKCXX.3-040-7-FW is a Bosch Rexroth Indramat EcoDrive in the DKC Drive Controllers series. It uses design version 3 and has a rated current of 40 A. The maximum input current is 16 A, which limits the current drawn by the device. Its DC bus has a nominal voltage of 700 V, while the maximum output voltage is 800 V for supplying the connected motor. The maximum output frequency is 1000 Hz, which establishes the upper frequency available for motor control.

The rated control-voltage input is 24 VDC, providing power to the control circuits. Control-supply power is 21 W. Continuous power dissipation is 180 W, indicating the heat produced during sustained operation; the separate power-dissipation rating at continuous current is also 180 W. The short-circuit current rating is 42,000 A RMS, indicating the maximum prospective short-circuit current associated with the device rating.

The maximum ambient temperature is 45ºC. Its nominal-operation ambient limit is also 45ºC, while reduced-output operation permits a maximum of 55ºC. The unit measures 360 mm in height, 65 mm in width, and 261 mm in depth. Installation requires at least 150 mm of clearance above the unit and 80 mm below it to support ventilation and heat removal. The device weighs 5.7 kg.
