150-F251NBR

The Allen-Bradley 150-F251NBR is an SMC Flex Smart Motor Controller from Allen-Bradley. This controller is commonly known as Soft-Starter however, the 150-F251NBR features more functions that enable it to function more than a basic soft-starter. It has standard configuration without optional modes installed however, it is capable of a variety of starting and stopping modes such as Soft-start, Linear Acceleration/Deceleration, Current Limit, Dual Ramp Start, Full Voltage, Soft Stop, Preset Slow Speed operating modes. This Smart Motor controller may implement these starting and stopping modes standard squirrel-cage induction motor or a Wye-Delta, six-lead motor. Aside from the starting and stopping modes, the 150-F251NBR has integrated motor overload protection, Diagnostic Faults and Alarms specifically Power loss, line fault, voltage unbalance, excessive starts/hour, phase reversal, undervoltage, overvoltage, controller temp, stall, jam, open gate, overload, underload, communication fault.It features Four (4) fully configurable contacts assignable for normal/up-to-speed/fault/alarm/network (N.O./N.C.), or external bypass signals. The 150-F251NBR is also capable of metering functionality, able to provide metering readout of Amps, volts, kW, kWh, MW, MWH, elapsed time, power factor, motor thermal capacity usage. This controller also has One (1) DPI port for connection of an additional human interface and another DPI port for connection to communication modules. The 150-F251NBR is capable of indicating Stopped, starting, stopping, at speed, alarm, and fault via the front panel LED indicators.

The Allen-Bradley 150-F251NBR SMC-Flex is a Solid State Controller that features an open enclosure. This module has a controller rating of 251 A, 200 Hp @ 460V AC and a rated voltage of 200-460V AC. It has an input voltage of 200-460V AC, 3-phase, 50 and 60 Hz and a control voltage of 24V AC/DC (5-480 A units).
