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).

This smart room sensor provides comprehensive HVAC control by measuring ambient light, relative humidity, and temperature. It measures temperature (0-50 °C) and relative humidity (0-95% rH). It controls devices like fans or dampers with a single analog output based on the measured values. It includes adjustable temperature/humidity ranges and an ambient light sensor. It provides humidity and temperature-dependent fan speed control. It's suitable for flush-mounted/surface-mounted installation and connects easily with spring-contact terminal blocks. It operates on 24 V DC. All data is accessible via Modbus RTU, and the firmware can be updated. It features LED status indicators with adjustable light intensity. It offers long-term stability and accuracy. It is used in sensitive areas such as data centers and museums.
