Capable of 8 ampere in 115, 230, and 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 DESCRIPTIO 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. RPM speed regulation control utilizes an external hall-effect sensor (counter through “HALL” connection) to precisely control and monitor fan speed. An internal PID controller provides system loop stability customized for your system. “Closed Loop Control” mode uses the second Analog Input (ANA2) that allows for closed loop control of the speed to any controlled parameter that can provide a 0-5 volt feedback signal. The PID parameters can be adjusted to provide stable controlled operation. Installing a distributed network of AirCare controls is simplified by flexible wiring options and diagnostic LEDs.
