Product Description:
Bosch Rexroth Indramat manufactured the RZW03.1-037-040. The RZW03.1-037-040 brake resistor is for high-performance use, especially in dynamic braking, where a lot of energy needs to be dissipated. It can handle a lot of energy turned into heat during fast deceleration because of its 37 kW power rating. To avoid overheating or system failure this high rating ensures the resistor can manage the kinetic energy generated by slowing down large inertial loads. The resistor is key to the operation and safety of industrial automation systems because it allows heat dissipation during braking so you can have precise motion control without risking the motor or drive. The resistor’s ability to dissipate cyclical power is determined by its 40% switch-duty cycle. For systems that need intermittent braking, this duty cycle is critical because it prevents the component from overheating during frequent brake activity bursts. This duty cycle is closely related to thermal management because the off-time allows cooling and prevents thermal overload while the on-time allows energy dissipation.
The brake resistor will perform long-term and reliable by operating within this duty cycle especially when subjected to the varying load conditions found in industrial automation. The RZW03.1-037-040’s thermal time constant of 150 seconds is a thermal parameter that determines how fast the resistor’s temperature changes in response to power changes. This means that whether the resistor is heating up or cooling down, it will reach 63.2% of its ultimate temperature difference in 150 seconds after a step change in power dissipation. Better heat management and less thermal stress are achieved by the resistor’s low thermal time constant, which prevents sudden temperature rise during braking. This feature ensures the resistor can work well in applications that require good thermal stability since braking events are sporadic rather than continuous.
The galvanized steel plate that houses the brake resistor provides a rugged and corrosion-resistant housing, which is critical for operation in harsh industrial environments. Galvanization extends the life of the component by protecting the resistor from corrosion and deterioration caused by moisture and humidity. The steel casing also provides a conductive path for thermal energy to be released to the surroundings. The resistor has an IP 23 protection rating, which means it is protected from objects bigger than 12.5 mm and from water spraying at an angle of up to 60 degrees. In environments where moisture and dust are a significant problem, this protection is important for safe operation. When combined, these features ensure the brake resistor’s ruggedness and performance in harsh automation environments.
