RZW02.1-110-060

Product Description:

Bosch Rexroth Indramat manufactured the RZW02.1-110-060. In demanding industrial drive systems, the Bosch Rexroth Indramat RZW02.1-110-060 brake resistor is designed to dissipate energy with high performance. It is designed to handle large amounts of regenerated energy during fast deceleration events with a peak power of 100 kW. This rating indicates the maximum instantaneous electrical power the resistor can convert into heat without risk of electrical or mechanical damage. Motor-driven systems discharge a lot of kinetic energy during dynamic braking, which returns to the DC bus. This surge can cause hazardous overvoltage conditions if there is no effective dissipation channel. By converting excess energy into heat, the RZW02.1-110-060 reduces that risk and keeps the drive system and its components intact. It’s essential in systems where rapid stops and high inertia are normal operating conditions because it can maintain this performance throughout repeated high load deceleration. The efficiency of the resistor to convert electrical energy into heat energy is directly influenced by the electrical resistance.

Dual resistance values of 2.7 Ohm at 40% switch-on time (Sd) and 5.4 Ohm at 60% Sd are given for this model. These values show how the internal heat profile of the resistor changes with varying duty cycles. Because of its lower resistance, the resistor conducts more current at 40% Sd and can dissipate faster. To prevent heat up and maintain thermal equilibrium after long usage, the resistance increases with increasing duty cycle. For engineers who need to match resistor behavior with the temporal profile of braking events, these features are very helpful. While keeping the system within temperature limits, its variable resistance design ensures energy management. An IP23 ingress protection grade protects against environmental exposure. According to this rating, the resistor is protected against water sprayed at angles up to 60° from vertical and solid objects larger than 12 mm.

Sensitive electrical components can be at risk from airborne particles, maintenance tool interactions and occasional water splashes, which are common in industrial environments. By not affecting the internal components of the resistor, the IP23 rating ensures system reliability and longer service life. This degree of protection allows the resistor to work without extra protective housing or environmental sealing for operators and system designers who operate in environments with mechanical risks and moderate moisture exposure. To stabilize the temperature, it provides a thermal buffer that smooths out occasional events and allows active and passive cooling. In systems with intermittent braking where energy demand varies, this is very important. Additionally, an integrated axial blower ensures active airflow through the unit and the housing is made of galvanized steel for corrosion resistance. Combined, these features improve mechanical durability and thermal management, making the RZW02.1-110-060 a reliable part of industrial automation systems that require strong braking and environmental resistance.
