AC motor 3,5 A | Temperature humidity control | 5 steps

Transformer fan speed controller with Modbus RTU communication. Supply voltage is 115 - 230 VAC. It controls single phase motors. The maximum motor current is 3.5 A The fan speed is regulated by varying the motor voltage in steps. Autotransformer technology produces a perfectly sinusoidal motor voltage. This ensures quiet operation of the motor. A special impregnated coating reduces electrical noise from the autotransformer. RTVS8 series are controlled by Modbus communication. The required fan speed can be set using potentiometers(SPV series), Modbus I/O modules or BMS systems or can be set depending on temperature, relative humidity, CO2 and air quality (TVOC) The housing can be surface mounted (protection class IP54).

A room transmitter can measure ambient light levels, relative humidity, and temperature. The distinctive enclosure accommodates flush or surface mounting. The supply voltage is 24 V DC. The sensor algorithm controls the single analogue output based on the measured values. This one output can be used to directly control an EC fan, an AC fan speed controller, or a damper actuator. There is a choice in output format. All measurements and the output value are accessible via Modbus RTU. The ambient light sensor can be used in a variety of applications to control the ventilation system based on the amount of people present in the room. Adjustments are possible for every setting with Modbus RTU. The light levels of the LEDs used for status indication are also programmable. This HVAC sensor is frequently used to regulate humidity and temperature in data centers, museums, wine cellars, etc.
