The HLR05.1W-70K0-N04R0-A-D7-NNNN from BoschRexroth is a high-end brakeresistor that converts the regenerative energy of the drive system to heat energy. This control of this equipment is executed through the brake chopper. This product is a variant 1 and line 5 braking resistor. The HLR05.1W-70K0-N04R0-A-D7-NNNN feature an air-cooling mechanism and an internal mounting style. The continuous power of this model is 70 kW, and the value of its braking resistance equals 4 Ohm. The protection type of this equipment is rated IP 20. Also, its nominal DC voltage is 750 volts.
The energy intake of the HLR05.1W-70K0-N04R0-A-D7-NNNN has a maximum rating equals 8,400 kWs, and the duration of its braking power is 70 kW. The maximum attainable braking power of this product is 124 kW, and its resistance is 4 Ohm (+/-) 10%. The peak power of this version of the HLR series is 106 kW at 650 Vdc and 168 kW at 820 Vdc. Its weight is approximately 145 kgs, and the cross section of its power connection has a value of 35 mm2. The connection cables used for the HLR05.1W-70K0-N04R0-A-D7-NNNN must be less than or equal to 100 meters.
Also, the return and feeder cables of this braking resistor must be kept in parallel and close together or twisted. This equipment must always be mounted in an upright position and on a horizontal surface. The design of the HLR05.1W-70K0-N04R0-A-D7-NNNN does not support wall mounting. A minimum recommended distance of 200 mm must be ensured between walls and heat-sensitive parts. When in operation, it is advisable not to touch the surface of this equipment because its temperature can attain a maximum of 150 degrees Celsius. This brake resistor can be shipped globally with a one-year warranty period from Wake Industrial.
