Assemblylinetechnologies continue to grow. Rexroth Group is one of the leading companies which continues to expand its range of products with time. The company currently offers solutions for assembly line technologies, hydraulic and pneumatic systems, control and driving mechanisms, and braking systems for VFD’s and converters. The brake resistors from Rexroth are well-known in the industrialautomation industry for their power handling capability and safety options.
The HLR01 series of brakeresistors work efficiently with the HCS03 series of converters. The series focuses on providing high energy-absorbing brakeresistors that are compact and relatively lightweight. The HLR01.1N-0780-N07R0-A-007-NNNN is another model that comes from the same series. It’s a 5.5 kg, compact brake resistor spanning across 223 x 300 x 210 millimeters of space. Compared to other models, it’s a relatively lightweight product with lesser space consumption. Rexroth made mounting and detaching the brake resistor very simple so that in the case of system failures, the unit could quickly be removed.
The HLR01.1N-0780-N07R0-A-007-NNNN can handle up to 93 kilowatts of reverse energy from the motors. It has a braking resistance of 8.2 Ohms so current can bypass through the resistor and braking operation at a high rate. The braking power duration is 0.78 kilowatts with an ON-time of just 1 second. The resistor is well-encapsulated which is vital for handling higher energy dissipation during the braking operation. The brake resistor, when mounted with the drive, is well- ventilated so that the system stays cool. The high dielectric strength also ensures better insulation and protection to the drive circuitry. For a compact design, the HLR01.1N-0780-N07R0-A-007-NNNN is more than just an efficient braking solution.
