Product Description:
The KDV 1.3-100-220/300-220/S100 is a supply module produced by Bosch Rexroth Indramat for the KDV Supply Modules series. This unit converts three-phase mains power into a stabilized DC link that feeds multiple servo drives or inverters within an automation cabinet, while also absorbing regenerative energy returned by the connected axes. Its role is to maintain constant bus voltage and manage braking energy so that each drive can focus on torque and speed control without individual power-conditioning hardware. Because the power stage is centralized, several connected axes can share one supply section instead of using separate rectifier hardware.
The module draws a nominal mains input of 220 V AC and is rated to deliver a continuous DC bus current of 100 A. For short dynamic events lasting up to 300 ms, it can supply up to 300 A, helping rapid motor accelerations without a major drop in link voltage. That voltage is held around 300 V DC, allowing standardized drive components to share the same bus. The unit’s maximum output capability is 30 kW, which is the total load that all attached drives can draw before thermal or conduction limits are reached. An internal bleeder resistor dissipates surplus regenerative energy and prevents overvoltage during deceleration or vertical axis motion. This arrangement helps the DC bus remain steady when one axis accelerates while another slows down.
The resistor can handle a peak of 40 kW for brief braking surges, while lower speed or holding events are covered by the 2 kW continuous bleeder rating. Control electronics and sensors are powered by a stabilized +24 V rail that supplies 8 A, eliminating the need for an external logic supply in most cabinets. Housekeeping functions, including the cooling fan, consume an additional 500 VA of auxiliary apparent power. All conversion and dissipation components are packaged in a chassis weighing 21 kg, which must be panel-mounted to allow heat to leave the unit effectively. This arrangement keeps control power available for monitoring and fan operation while the main DC bus serves the connected drive sections.
