SP-142757

The SP-142757 from Allen Bradley features a high-performance SCR Cell Assembly Kit specifically designed for regenerative applications. Rated for a maximum current of 670 Amps, this part is ideally suited for demanding environments. It handles AC source voltages of either 230 V or 460 V, displaying versatility for various setups.

With NEMA 1 / IP20 protection, the assembly is well-guarded against dust and moisture, making it suitable for indoor use. Its operational capabilities extend with a horsepower range of 250-300 HP at 230V and 250-400 HP at 460V, ensuring that it meets a range of performance needs. For cooling, it employs conduction through the drive chassis heatsink, facilitating effective thermal management during operation.

The mounting of the unit utilizes a bolt-on style, which simplifies integration into existing systems. Terminal connections are made via screw terminals and a bus bar interface, allowing for straightforward installation. The assembly is rated to function in ambient temperatures from 0 °C to 55 °C, and can sustain high humidity levels up to 95% without condensation.

Designed to operate efficiently at altitudes of 1000 meters, the kit can withstand storage temperatures ranging from -20 °C to +70 °C. This robust assembly is constructed with three SCR cells per drive bridge, along with upper and lower snubber boards, enhancing its operational reliability in various applications.
