Product Description

The HLR01.1N-44K0-N03R3-B-007-NNNN is a brake resistor produced by Rexroth Indramat, which is one of the most reputable manufacturers of industrial automation parts in the world. The HLR01.1N-44K0-N03R3-B-007-NNNN brake resistor consumes the excess electrical energy returned into the power circuit of a variable frequency drive during the deceleration of the servo motor, leading to a generation of an instant braking effect on the motor. It is an essential additional component necessary to extend the service life of the Indramat servo drive system. The HLR01.1N-44K0-N03R3-B-007-NNNN braking resistor is more reliable and requires less service than the conventional frictional brakes; that is, it is much more cost-effective for industrial production processes.

The HLR01.1N-44K0-N03R3-B-007-NNNN brake resistor has an international protection rating of 23, meaning that the resistor's housing casing protects the internal components from harmful environmental interference such as touch by fingers greater than 12.5 millimeters and water sprayed at any angle less than 60 degrees from vertical. The housing casing is also specially coated with insulating elements, which prevents heat accumulation around the resistor. The DC bus nominal voltage of the braking resistor is 700 volts. Since the HLR01.1N-44K0-N03R3-B-007-NNNN brake resistor produces a lot of heat, combustible materials should not be installed close to the resistor as it can lead damage to such industrial components.

The HLR01.1N-44K0-N03R3-B-007-NNNN has a continuous power output of 44kilowatts and a fixed ohmic resistance of 3.3Ohms. HLR01.1N-44K0-N03R3-B-007-NNNN braking resistor can, however, absorb a regenerative power of up to 2000kilowatts during motor deceleration. The resistor's heat is regulated by natural convention with an air current of at least 150meter cube per hour. The maximum cable diameter that can be passed through its conduit is specified in the resistor's documentation. This brake resistor can be shipped globally with a one-year warranty period from Wake Industrial.
