HLR01.2N-01KO-N28RO-E-007-NNNN

The Bosch Rexroth Indramat HLR01.2N-01KO-N28RO-E-007-NNNN from the HLR Brake Resistors series is engineered as an external braking resistor for seamless integration with the HCS 02 and HCS 03 drive controllers. This unit features Construction Type: N and supports Free Assembly: Yes for unrestricted installation above the HCS controller. With a Continuous Power: 1 kW rating and a DC Bus Voltage: 700 V, it efficiently handles kinetic energy conversion for regenerative applications. The resistor’s Resistance: 68 Ohms, Protection Rating: IP 54, and Cooling: Natural Convection ensure reliable operation in demanding environments.

Built on a robust steel-grid design, this resistor exemplifies its Function: Energy Conversion capability by absorbing high levels of regenerative energy and dissipating it safely as heat. It endures ambient temperatures from 0 °C to 40 °C without derating, while the Peak Power: 25.82 kW capability provides reliable performance during short bursts of heavy braking. Weighing just 3.96 kg, the compact footprint demands only 200 mm of clearance above and below the unit inside the control cabinet. Installation integrity is maintained with 16 AWG wire per UL 508 A and NFPA 79 standards, accommodating a maximum permissible on-time duty of 1.16 s and cycle time up to 33.30 s.

This HLR resistor’s lightweight, Type N construction and minimal space requirements simplify cabinet layouts while safeguarding drive controllers from regenerative overvoltage. Designed specifically for the Bosch Rexroth HCS series, it delivers consistent braking performance, reducing system downtime and protecting sensitive electronics. For applications demanding continuous, high-capacity energy absorption, the HLR01.2N-01KO-N28RO-E-007-NNNN offers compact reliability and straightforward integration.
