150-SD2NUR

The Allen Bradley 150-SD2NUR represents a solid state motor controller engineered for robust performance under challenging conditions. This unit operates with a rated voltage of 200 V and boasts a high current rating of 420 A, making it suitable for various heavy-duty applications. Designed for continuous operation, it dissipates power with a rating of 1260 W, ensuring effective thermal management.

With an operating frequency range established between 47 and 63 Hz, the controller allows for sufficient flexibility in different installations. It employs an electronic overload system which is essential for protecting motors from excessive current, rating the trip class between 5 and 30. The trip current rating is calculated at 118% of the motor's full-load current, allowing for precise control.

Offering vital features such as a rated impulse voltage of 6000 V, the 150-SD2NUR can manage transient voltage conditions efficiently. Additionally, it withstands dielectric voltage of up to 2500 V, enhancing its reliability in various environments.

During power interruptions, the controller assures ride-thru capabilities for a duration of 22 ms, which helps sustain control signals. The maximum output current at 24 VDC is specified at 300 mA, enabling appropriate control over connected devices. The unit can operate in relative humidity conditions ranging from 5% to 95% (non-condensing) while maintaining an operational temperature environment between 40 to 65 °C.
