HNL01.1E-1000-N0012-A-500-NNNN

HNL01.1E-1000-N0012-A-500-NNNN, Bosch Rexroth Indramat, HNL Mains Chokes opens new possibilities for power conditioning in DC bus applications. This Variant 1 mains choke is engineered to interface seamlessly with non-regenerative converter supplies, offering a nominal inductance of 3 X 1000 mH and a continuous current rating of 12 Amp. Weighing only 2.7 kg, it delivers high performance in a compact, rugged housing with no additional options by default. The device type is classified as A, making it a standardized solution across the HNL series.

Designed for three-phase networks between 380 - 500 V, the unit tolerates mains deviations of –15 % to +10 % without derating. Its Mains Short-circuit Current Rating of 100 kA ensures robustness under fault conditions, while Power Dissipation is limited to 40 W to maintain thermal stability. The choke’s single-line topology (Line 1) and compact form factor simplify panel layout, and its hardened construction supports ambient temperatures from –10 °C to +50 °C in operation. No additional options are fitted, and the series’ standardized dimensions facilitate drop-in replacement.

Integration of the HNL01.1E-1000-N0012-A-500-NNNN with Bosch Rexroth Indramat HCS01 converters and other feeding supply units enhances DC bus stability and suppresses harmonics for cleaner mains currents. Its reliable design reduces system perturbations and extends component life by smoothing inrush currents and mitigating voltage spikes. This mains choke is an ideal choice for industrial drives, automation systems, and power supply networks seeking a compact, high-reliability harmonic filter.
