AC motor 2,5 A | Temperature humidity control | 5 steps

Transformer fan speed controller with Modbus RTU communication for manually or demand-based fan speed regulation. The supply voltage ranges from 115 to 230 VAC. It is used for single-phase motors. The maximum motor current (combined) is 2.5 A. Modbus communication is used to control the RTVS8 serie. The fan speed is controlled by gradually varying the motor voltage. The autotransformer technology produces a perfect sinusoidal motor voltage. This ensures that the motor runs quietly. The electrical noise from the autotransformers is reduced by a special impregnated coating. To adjust the requested fan speed a potentiometer (SPV series), Modbus I/O module, or BMS system can be used. The fan speed can also be adjusted based on the temperature, relative humiudity, CO2 and air quality (TVOC). Surface mounting is possible (IP54 protection).

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.
