Product Description:
The KDV 1.3-100-220-300-220-380 supply module is produced by Bosch Rexroth Indramat within the KDV Supply Modules series. It functions as a three-phase rectifier and energy management unit, delivering a stabilized DC link to multiple servo drives in industrial automation systems. By consolidating braking energy and auxiliary loads, the module stabilizes system voltage and simplifies wiring for motion axes, making it a standard choice for packaging, printing, and material-handling machinery.
It accepts a three-phase mains at a nominal input voltage of AC 220 V and can draw a rated current of 100 A during continuous operation. The rectified output is held at DC 300 V, forming the common bus that runs the connected inverters. Dynamic braking energy is absorbed by an internal bleeder resistor that can dissipate 2 kW continuously and tolerate up to 40 kW in short bursts, preventing overvoltage when axes decelerate simultaneously. Control electronics are powered by a dedicated 24 V rail that supplies 8 A, while cabinet auxiliaries may draw up to 500 VA through the auxiliary power tap. An integrated fan rated at 15 VA provides forced airflow across heat-generating components, and the three-phase topology helps balance load across the supply transformer.
For transient load surges, the DC bus can deliver a peak current of 300 A for 300 ms, and the module can absorb regeneration up to 60 kWs before the braking chopper reaches its limit. Heat rejected into the enclosure is limited to a cabinet power loss of 150 W, though the total external dissipation from attached drives must stay below 2000 W to maintain thermal margins. Reliable operation is specified up to an installation altitude of 1000 m under humidity class F and insulation category C conditions, ensuring adequate dielectric spacing and moisture tolerance inside typical factory environments.
