Single-phase motor controls 115 - 230 VAC
Transformer fan speed controllers for single-phase voltage controllable motors. The supply voltage is in the range of 115 - 230 VAC. They control AC fan speed by varying the motor voltage in steps. The requested fan speed can be adjusted manually or automatically via Modbus RTU communication. In combination with a Sentera HVAC sensor, demand based ventilation control is possible.
