The Bulletin 150, solid-state controller by Allen-Bradley has an open enclosure type, an input line voltage of 200-480V AC, 3-Phase, 50/60Hz, a control voltage of 100-240V AC, with an option for pump and braking control. The size of the controller is 11.42 inches (W) X 23.62 inches (H) X 10.89 inches (D). The controller also has a temperature rating of -5 to 50 degrees (C). Storage temperature should be maintained at -25 to 75 degrees (C), while humidity of storage conditions should fall between 5-95%, non-condensing. Standard features include power and control wiring, keypad and software, one DPI for communications, starting and stopping modes, protection and diagnostics, metering, alarm contact, status indication, and auxiliary contacts. Starting and stopping modes include soft start, current limit start, dual ramp, full voltage, linear speed acceleration, preset slow speed, and soft stop. With respect to the standard features, power wiring is a standard squirrel-cage induction motor or a Wye-Delta, six-lead motor; control wiring is a 2-and-3 wire control for a wider array of applications. The keypad is a front-facing pad with a backlit LCD display, and the software parameter values are available for download by utilizing the Connected Components Workbench, DriveTools, and DriveExplorer software bundles. Starting and stopping modes include soft start, current limit start, and many more. Protections and diagnostics cover a wide array of situations, including power loss, line faults, voltage unbalance, excessive starts per hour, phase reversal, and more. Metering includes measurements in amps, volts, kW, KWh, MW, MWH, elapsed time, power factor, and motor thermal capacity usage.Alarm contact includes overload, underload, undervoltage, overvoltage, unbalance, jams, stalls, and ground faults. Status indications included with the SMC-Flex include indications of stop, start, stopping, at speed, alarm, and fault. The SMC-Flex also includes four fully programmable contacts as normal/up-to-speed/fault/alarm/network, or external bypass.
