Q9 Low Voltage

Variable Torque HVAC


The Q9 Adjustable Speed Drive is a solid-state AC drive designed for commercial variable torque applications such as fans and pumps for VAV systems, cooling towers, and pump systems. The Q9 features a multi-function LCD display that provides a programming interface, monitoring display, and operation mode. The Q9 provides protection against drive overload, motor overload, overvoltage , and ground faults, to name a few. These features make the Q9 suitable for a wide variety of applications that require reliable motor control.
