Product Description

The HLR01.1N-66K0-N04R2-B-010-NNNN brake resistor is one of the best productions of Rexroth Indramat. The brake resistor is applied in servo drive systems to convert regenerated energy into thermal energy. The brake resistor is produced specifically for the HSC03 and the HSC02 servo drive series. It is designed with an ohmic resistance of 4.2 Ohms; this provides the resistor with high load capacity and allows it to function in servo systems that produce a very high amount of regenerative energy. The operation of the HLR01.1N-66K0-N04R2-B-010-NNNN in the servo system requires the connection of an HLT brake chopper or braking unit to the servo drive. The brake chopper helps control the brake resistor since the drive controller does not contain an internal control unit for the resistor.

The HLR01.1N-66K0-N04R2-B-010-NNNN brake resistor has a continuous power output of about 66 kilowatts. The brake resistor should be installed directly above the servo drive; this unique installation technique allows for the utilization of the converter’s exhaust airflow to cool the servo drive. To prevent property damage, combustible materials should be installed as per the minimum installation distance specified in the drive’s documentation. The house casing of the resistor is according to IP 20 protection class. The bus voltage of the resistor is 1000volts.

The HLR01.1N-66K0-N04R2-B-010-NNNN brake resistor can also absorb regenerative power of up to 5000 kilowatts and thus can function in fairly large industrial machines such as railcars with multiple light units, electric trams, electric and hybrid electric and hybrid automobiles, and even some conveyor belts. The brake resistor operates optimally in an ambient temperature range of 0 to 40 degrees Celsius. It also has a minimum cycle time of 120 seconds. This brake resistor can be shipped globally with a one-year warranty from Wake Industrial.
