RZW02.1-011-040

The RZW02.1-011-040, Bosch Rexroth Indramat, RZW Braking Resistors unit is engineered for dynamic braking in industrial automation systems. It converts kinetic energy from motion drives into heat, safeguarding sensitive electronics during rapid deceleration of frequency converters. The robust through-hole package integrates seamlessly onto control boards and maintains consistent performance under fluctuating loads. With a nominal power dissipation of 10 Watt, this resistor delivers both precision and endurance in continuous operation.

Specifically, the device presents a resistance of 40 Ohm with a tight tolerance of ±1% and a temperature coefficient of 50ppm/°C, guaranteeing minimal drift across wide thermal ranges. It withstands up to 500 V DC and can absorb short-term energy spikes at a peak dissipation of 10 kW, while its continuous power rating supports frequency converter outputs up to 11 kW. Constructed from tinned copper, the resistor offers superior conductivity, corrosion resistance, and thermal stability. The through-hole mounting type ensures mechanical security on standard PCBs, and with an operating factor of 40 % SD, it balances load demands against component lifetime.

Engineers benefit from straightforward integration into drives, motor controllers, and PLC cabinets, leveraging its standard footprint and predictable thermal behavior. The rugged construction and precise specifications of the RZW02.1-011-040 deliver high reliability, reducing maintenance cycles and downtime in demanding industrial environments. Its ability to efficiently absorb braking energy makes it an ideal choice for frequency converter braking circuits, hoist controls, and other dynamic motion applications.
