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

This is a transformer fan speed controller with Modbus RTU communication. It's designed for manual or demand-based fan speed regulation of single-phase motors, handling a maximum current of 2.5 A with a supply voltage of 115 - 230 VAC. The controller uses autotransformer technology to vary motor voltage, ensuring a perfect sinusoidal waveform and quiet operation. A special impregnated coating on the autotransformer reduces electrical noise. Control is highly flexible, allowing for regulation via a potentiometer, Modbus I/O module, a BMS system, or based on environmental parameters like temperature, humidity, CO2, and air quality. The unit is housed in an IP54-rated enclosure for surface mounting.

This smart room sensor provides comprehensive HVAC control by measuring ambient temperature, relative humidity, and ambient light. It measures temperature from 0 to 50 °C and relative humidity from 0 to 95% rH. The sensor controls devices like fans or dampers with a single analog output based on the measured values, providing humidity and temperature-dependent fan speed control. It includes adjustable temperature/humidity ranges and an ambient light sensor. It is suitable for both flush-mounted and surface-mounted installation, and it connects easily using spring-contact terminal blocks. The sensor operates on 24 V DC. All data is accessible via Modbus RTU, which also allows for firmware updates. The device features LED status indicators with adjustable light intensity, offering long-term stability and accuracy. It is ideal for use in sensitive areas such as data centers and museums.
