AC motor 5 A | temperature humidity control | TK monitoring

This transformer fan speed controller with Modbus RTU communication is designed for controlling single-phase motors up to 5 A with a supply voltage of 115 - 230 VAC. It allows for both manual and automatic speed regulation based on demand. The controller uses autotransformer technology to gradually vary motor voltage, ensuring a perfectly sinusoidal output for quiet operation. A special impregnated coating on the autotransformer reduces electrical noise. Control can be managed via various options, including Sentera HVAC sensors, potentiometers, Modbus I/O modules, or BMS systems. The unit has an IP54-rated enclosure for surface mounting, protecting it from dust and moisture.

The ODTHM is a multifunctional sensor designed to measure temperature, relative humidity, and ambient light in outdoor environments. It measures temperature (-30—70 °C) and relative humidity (0—100% rH, non-condensing). Based on these measurements, it calculates the dew point temperature. It offers day/night detection with an ambient light sensor, featuring adjustable "active" and "standby" levels based on ambient light intensity. Selectable temperature and relative humidity ranges are also available. It operates with Power over Modbus (PoM). All parameters and measurements are accessible via Modbus RTU (RS485). Firmware can be updated via Modbus RTU communication thanks to its bootloader feature. The enclosure has an IP65 protection rating (according to EN 60529), providing high protection against dust and water. This outdoor sensor is ideal for reliable environmental monitoring, even in demanding conditions.
