Product Description:
The KDV2.2-100-220/300-W1 supply module from Bosch Rexroth Indramat is part of the KDV Supply Modules series and energizes AC drive groups through a shared DC link. Besides rectifying line power, it furnishes a safeguarded 24-volt rail that can deliver 12 A for control electronics, and it supports external devices with an auxiliary supply rated at 500 VA. A dedicated blower branch may draw up to 1000 VA to cool connected drives. Internal conversion losses are limited to 150 W, while the housing carries an IP10 protection rating suitable for installation inside a sealed cabinet. This arrangement allows one central module to support multiple connected axes while keeping low-voltage control power separate from the main drive bus.
At the incoming side, the module accepts a three-phase nominal input of 220 V AC and rectifies it into a regulated rail of 300 V DC. Under continuous duty, the unit supports a bus load of 30 kW and can source up to 100 A of current to parallel inverters. Short acceleration bursts are covered by a peak current reserve of 300 A for 300 ms. The integrated bleeder dissipates regenerated energy at 2 kW continuously, preventing overvoltage when axes brake, and its heat is supplemented by 2000 W of external cabinet loss allowance. The current and power limits must be matched to the combined demand of the connected inverters so the shared bus remains stable during acceleration and braking.
For rapid deceleration events, the bleeder can absorb 40 kW in short peaks, and the shared capacitor bank stores up to 100 kWs of feedback energy before the resistor is engaged. Reliable operation is maintained up to an ambient temperature of 55 °C, and derating is required beyond that point. The mechanical design weighs 17 kg, enabling drawer-style installation in multi-axis cabinets. This layout is useful in cabinet systems where the power section is grouped in one area and several servo axes draw from the same DC bus. The energy-handling capability also helps the module manage repeated braking events without relying on a separate regenerative supply stage.
