The Allen-Bradley 150-SB2NBR, part of the SMC-50 smart motor controller range, features advanced control capabilities using SCR technology to manage motor torque during all operational phases. It supports operation within a 3-phase 200 to 480 Volts AC line, accommodating both 50 and 60 Hertz frequencies. In normal duty mode, the controller delivers 110 Amps for line-connected loads, while the output increases to 190 Amps for delta-connected setups; in heavy-duty mode, it adjusts to 90 Amps and 155 Amps respectively. Configurable via an optional HMI controller or onboard keypad and LCD, the controller includes diagnostic LED indicators and supports network adaptability through optional communication modules. The unit's robust design, with an IP00 open enclosure rating, ensures efficiency within temperatures of -20 to 40 degrees Celsius and between 5% to 95% relative humidity, necessitating a vertical mounting for optimal performance.
