The 150-F201FHD SMC-Flex Smart Motor Controller by Allen-Bradley is a solid-state motor Controller with a compact and modular design used for the unique microprocessor control of 3-phase squirrel cage induction motors. The 150-F201FHD is a soft starter in the SMC-Flex Controller series, which offers intelligent motor control, and it comes with an integral bypass, which reduces heat loss, electronic footprint, and enclosure size to save space. The 150-F201FHD has an operational rating of 201A, with power output range of 75 to 100HP at 480V AC, and it has an operational voltage range of 200 to 208V AC at 50/60Hz. Its power circuit has an acceptable voltage range of -15% to +10% at 46 to 63Hz, with an IEC rated impulse voltage of 6000V, and a dielectric 2,200V dielectric withstand. The controller's power circuit is protected with a 1600A Class L fuse, with 30KA maximum short-circuit rating, and it provides DV/DT protection using an RC Snubber Network. The controller has an installed Metal Oxide Varistor (MOV) which provides protection against transient voltage spikes and surges, and it provides overcurrent protection, voltage unbalance, stall protection, and motor jam detection.

The 150-F201FHD has a control circuit with 100 to 240V AC operating voltage, and 1600V AC dielectric withstands, and it has 4 programmable auxiliary contacts, with 3A and 1.5A contact ratings at 120V AC and 240V AC, configured for normal, up to speed, fault, and alarm systems. Cooling is provided by a 59VA heatsink fan, with 100 to 249V AC power input, and the controller had a maximum heat dissipation of 200W. It has 7 operational modes with digital setups and it has a front panel keypad with Liquid Crystal Display, for programming. The controller can also be configured through the DPI connected HIM modules with limited configuration parameters, and it is also configured via PC-based software downloaded directly to the controller. The 150-F201FHD has a functioning temperature range of -5 to 50°C (+23 to 122°F), at a relative humidity range of 5 to 95% without condensation, and it is stored at –20 to 75°C temperature. It is built to withstand 5.5G operational shock for 11ms, with 1G peak vibration for 60 minutes, and it can remain functional at a maximum altitude of 2000m. The 150-F201FHD weighs just about 30.4Kg, with approximate shipping dimensions of 560mm x 225mm x 253.8mm, and it is CE and cUL-us certified.
