Electronic fan speed controller
4 - 20 A | V Series AirCare Automation

The AirCare VariPhase™ is a Network or Analog controlled Fan/Blower Control for use with Single-Phase Permanent Split capacitor (PSC) or Shaded-Pole Induction Motors. Capable of 4 ampere in 115, 230, and 3 ampere in 277 volt models, these controls offer a 3-wire (higher efficiency and lower noise) or traditional 2-wire connection option. Open-loop or Closed-loop operation is selectable. AirCare VariPhase™ has network connectivity (MODBUS® RTU-based) through RJ45 to any controller or AirCares' Proprietary Control System. Analog Control input allows manual control or analog inputs from any PLC or system controller.

PRODUCT DESCRIPTION
AirCare VariPhase™ controls combine intelligent speed control with industry standard MODBUS® RTU networking. The versatile design allows for either analog (0-5V or 20mA) or network speed control. In network mode VariPhase™ units can have up to 125 unique addresses that can be precisely controlled from our proprietary AirCare Console™., AirCare system controller your PLC or Building Management System (BMS). For optimal efficiency and reduced acoustic noise, VariPhase™ models include intelligent auxiliary winding control using a 3rd wire to the motor. Soft-start options are also available. Permanent Split Capacitor (PSC) motor loads can be connected in three-wire mode or wired conventionally for standard operation.
