Product Description

The Bosch Rexroth HNL01.2R-0540-C0094-A-480-NNN is a mains choke. It is designed to be connected to three-phase AC mains with 400 to 480 Volts AC voltage range and 50 / 60 Hertz frequencies. When used with compatible IndraDrive drives, the HNL01.2R-0540-C0094-A-480-NNN is installed between the mains filter and the main contactor. The continuous current rating for the choke is 94 Amps and it dissipates 420 Watts as heat during operation. This heat dissipation is a factor that needs to be considered in system design. Inductance of the HNL01.2R-0540-C0094-A-480-NNN is 520 microhenry. The choke includes 20 microfarad capacitors as additional options. The choke is available in a IP 10 rated housing and supports regenerative supply systems. Approximate weight of the choke is 65 kilograms and its dimensions are 340 x 385 x 220 millimeters.

The HNL01.2R-0540-C0094-A-480-NNN can be ordered as an accessory for IndraDrive systems. It is not mandatory to use mains chokes. However the use of chokes offers several benefits including the ability to reduce harmonic distortion and to protect the drives from harmful surges and spikes in the AC supply. Additional benefits include higher continuous power in DC bus. Chokes such as the HNL01.2R-0540-C0094-A-480-NNN must be used with regenerative supply units. Other accessories can also be ordered to improve various characteristics of the control system. Mains filters suppress leakage current generated by capacitors and help to ensure compliance with EMC limit values. Mains filters with built-in mains chokes simplify installation. DC chokes also help to achieve higher DC bus power. Motor filters help to reduce leakage current and transient overvoltages on long motor wires. Brake choppers are used with braking resistors to increase available braking power. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
