The 150-S361NBD controller is a motor controller featuring an internal bypass and is part of Allen-Bradley's microprocessor-controlled SMC-50 series. This controller delivers up to 361 Amps of output current and accepts input voltages from 200 to 480 Volts AC, specifically supporting three-phase input at line frequencies of 50 to 60 Hertz. It features two relay outputs and two 24 Volts DC inputs, with a control voltage of 24 Volts DC. The working temperature range for this open enclosure controller is between -20 and 50 degrees Celsius, while storage should be at -25 to 75 degrees Celsius. During operation, it should maintain a non-condensing relative humidity level of 5% to 95%.
The 150-S361NBD meets UL508 and EN 60947-2 standards and is approved by ABS, KCC, CCC, and CE. It measures 51 x 36 x 14 inches and has a heat dissipation rate of 120 Watts under continuous duty.
