Product Description:
The 24.DR.B18-1541 is an input choke produced by KEB within the DR Motor Input Chokes series. Installed between the supply network and a frequency inverter, this passive component dampens line-side harmonics and limits inrush currents, thereby protecting both the drive and upstream equipment in industrial automation systems. By adding impedance ahead of the rectifier bridge, the choke lowers current ripple, improves the inverter’s DC bus stability, and helps the installation meet electromagnetic compatibility limits without active filtering.
The choke presents an inductance of 0.15 mH, a value chosen to attenuate high-frequency components without producing an excessive voltage drop. Under continuous operation, it carries a nominal line current of 200 A, so the copper windings and laminated core are sized for high-power drive cabinets. It is designed for a network voltage of 400 V, aligning with common low-voltage distribution systems in industrial plants. With an impedance of 4%, the component introduces controlled series impedance that reduces harmonic distortion while maintaining acceptable efficiency. Thermal dissipation during full-load service amounts to 168 W; this value helps determine the enclosure ventilation needed to keep the choke within its permitted temperature range.
Mechanical integration is aided by a conductor cross-section of 95 mm², allowing suitably sized cables to be clamped with low-resistance connections. Mounting is accomplished through slots measuring 7 × 12 mm, so the unit can be secured to a back panel or base plate with appropriately sized hardware. The laminated core and coil assembly fit within overall dimensions of 267 × 215 × 310 mm, permitting placement next to drives while preserving clearance for airflow. Designed for three supply lines, the choke matches the phase arrangement of typical three-phase induction motor drives. Its passive design requires no separate control circuit or active switching components during normal operation.
