8/21/2008 VariPhase B-Series Specification Rev. 1.0 Product Specification Sheet VariPhase B-Series Controls AC Motor Speed Control Models ACB1121 & ACB1122 Overview AirCare’s B-Series VariPhase sets a new standard in wall-mount motor speed controls by improving efficiency, adjustment accuracy and linearity. The internal microprocessor provides precise control of motor speed over a wide range, while a user-selectable soft-start feature eliminates high-startup currents typical of AC induction motors. VariPhase B-Series controls are designed to be panel-mount in OEM equipment and require only a few simple electrical connections. They are suitable for both new and retro-fit applications. The VariPhase B-Series also has a convenient On/Off switch that allows the user to switch the motor on and off without changing the speed setting. Features • Variable voltage control of PSC and shaded-pole AC motors • Linear speed adjustment range (improved over light-dimmer types) • Easy to install in OEM equipment • Jumper selectable soft-start • Installer adjustable minimum speed limit (to prevent motor stall) • LED indicator shows when motor is running at min. speed or greater Models AC Voltage Current 115V 230V 12.0A ACB1121 ACB1122 Specifications Parameter Min Typical Maximum Notes ACB1121 Supply Voltage (Vrms) 97V 115V 132V ACB1122 Supply Voltage (Vrms) 195V 230V 265V Load Current (Irms) 12.0A Ambient Temperature Range (°F) 0°F 70°F 90°F
