The 150-F780NCA is an SMC Flex Smart Motor Controller manufactured by Allen-Bradley. This motor controller is engineered to support extremely powerful motors with up to 600 Horsepower (at 60 Hertz) and 560 kW (at 50 Hertz). Its input terminals are usually connected to 575 Volts AC three-phase voltage, but it can work with 200 to 575 Volts AC voltages. Independently, the user must provide a 230 to 240 Volt AC power to the controller for proper operation. The power source for this purpose must have a minimum capacity of 810VA to support internal sub-modules like control module with 75 VA, bypass contactors with 526 VA, and fan assembly with 150 VA. The output current delivered to the motor being controlled covers 260 to 780 Amperes range. This is an Open and Non-Combination type of controller. Its enclosure is IP00 rated and it has a heatsink fan.

A 230 Volt AC control voltage can be provided through the terminal block CP1, at terminals 1 and 4. Incoming line terminations are positioned at the top of the device and line motor connections are positioned at the bottom of the controller. Conductors connected to the input line and to the motor should be around 240 millimeters squared. The Allen-Bradley 150-F780NCA supports 8 modes for a motor start. It also features communication, metering, various protections, inside delta connection, and it has an LCD display with a keypad for programming and diagnostic purposes. This SMC Flex Smart Motor Controller comes open with dimensions of 1041.1 millimeters (41.0 inches) x 596.9 millimeters (23.5 inches) x 346.2 millimeters (13.63 inches). It is shipped with the approximate weight of 179 kilograms (395 pounds).
