HNL01.1E-0100-N0220-A-480-NNNN

The Bosch Rexroth Indramat HNL01.1E-0100-N0220-A-480-NNNN from the HNL Mains Chokes series is engineered to integrate seamlessly with converters and feeding supply units. Designed for an IP10 protection type enclosure and a rectifier supply system, this mains choke offers robust line conditioning and harmonic mitigation. Fitted in any orientation, the unit features reactive power compensation to discharge the supply system and maintain stability across high-demand drive applications. With an additional option: None, the device ensures streamlined installation without the complexity of modular add-ons.

In operation, the HNL choke suppresses RFI disturbances generated by switched-mode power supplies and motors, preserving the integrity of the DC bus and minimizing recharging currents in large drive systems. Harmonic compensation is built in to deliver a near-sinusoidal current waveform that meets stringent EN 61000-2-4 EMC requirements. The choke's series connection with AC line power reduces voltage spikes, sags, and converter-induced perturbations, effectively extending servo drive lifespan. Its capability to absorb power-line disturbances also protects the supply transformer from shorting events.

Installation inside a machine or system ensures safe, reliable performance, while compliance with safety instructions and a mandatory half-hour cooling period prevent personal injury or equipment damage. Delivered through trusted logistics carriers, the HNL01.1E-0100-N0220-A-480-NNNN mains choke includes a one-year warranty for peace of mind. This compact solution enhances total power factor and delivers continuous DC bus support in demanding industrial environments.
