DKC11.3-040-7-FW

DKC11.3-040-7-FW is a Bosch Rexroth Indramat EcoDrive in the DKC Drive Controllers series. It uses design 3 and interface option 11 for connection to the associated control system. The controller has a rated current of 40 A, a type current or peak current 1 of 40 A, and a maximum input current of 16 A. Its 700 V nominal DC bus has 0.27 mF of nominal capacitance. The maximum control charging current is 4.0 A, while the maximum control overvoltage is 45 V for 1 ms. The maximum DC-bus charge and maximum energy dissipation are each 5.0 kWs.

The controller reaches a maximum output frequency of 800 Hz at an 8 kHz switching frequency; the separate fs=8 kHz rating also gives a maximum of 800 Hz. Control power consumption is 18 W. Device power dissipation is 180 W, and power dissipation at continuous current is also 180 W. The bleeder handles 0.15 kW continuously and 10 kW at peak to dissipate regenerated energy. Soft starting uses a 60-ohm resistor rated at 0.15 kW to limit charging current. A ZKS DC-bus dynamic brake is not present.

The unit operates at ambient temperatures up to 45ºC and installation altitudes up to 2,000 m. It supports up to 95% relative humidity and 25 g/m³ absolute humidity. Allowable contamination degree 2 permits normally nonconductive contamination, with temporary conductivity possible from condensation. IP20 protection prevents access by fingers and similar objects but does not protect against water.

The enclosure measures 65 mm in width, 360 mm in height, and 261 mm in depth. The individual width, height, and depth ratings are also 65 mm, 360 mm, and 261 mm, respectively. Its mass is 5.7 kg, and its weight is also 5.7 kg.
