Product Description
The Allen-Bradley 150-A97NB is an SMC-2 solid-state, three-phase smart motor controller designed for 380-460V AC, 50-60 Hz power systems. It's rated for 97A, handles motors up to 30 HP (200-230V AC) or 75 HP (460-575V AC), and supports motor power up to 25 kW (220V AC), 45 kW (380V AC), 55 kW (415V AC), and 63 kW (500V AC). This open-type controller, weighing 23 lbs (10.5 kg) and dissipating a maximum of 285W with a 45 VA heatsink fan, should be stored between -40 and 85C and operated between 0 and 50C at altitudes below 2000m. It lacks protective and interface modules but features an LED status indicator for power and fault diagnostics (stalled motor, phase loss, shorted SCR), DIP switches, a rotary digital switch for configuration, and selectable full voltage, current limit, and soft start modes, along with an energy-saving feature for light or unloaded motors.
Is Your Device Showing These Signs?
The Allen Bradley 150-A97NB SMC Flex Smart Motor Controller commonly experiences issues such as failed SCRs, blown fuses within the power structure, and communication faults on the DeviceNet network due to corrupted firmware or damaged communication ports. Overload trips are frequent, stemming from incorrect parameter settings or a malfunctioning current transformer. Internal power supply failures and issues with the control board, leading to unresponsive operation or erratic behavior, require immediate attention. Component degradation due to thermal stress and age is a factor, necessitating component-level repair or complete unit replacement.

Our Repair Process for the
150-A97NB
Our repair process for the Allen Bradley 150-A97NB SMC Flex Smart Motor Controller begins with a comprehensive diagnostic evaluation to pinpoint the failure. This includes a thorough inspection of SCRs, fuses, and the power structure, followed by a complete assessment of the DeviceNet communication network for firmware corruption or port damage. Overload trip causes are investigated through parameter verification and current transformer testing. Internal power supply functionality and control board operation are scrutinized to identify unresponsive or erratic behavior. Component-level repairs are executed to address degradation from thermal stress and age, with complete unit replacement performed when component-level repair is not feasible.
