Additional specifications and description
Temperature based fan speed control
This variable speed controller requires an optional PT500 temperature probe, e.g. FLTSN-P500-040. When the measured temperature is lower than the temperature setpoint, the fan runs at low speed. When the selected temperature is exceeded, the fan accelerates. The higher the measured temperature, the higher the fan speed. The temperature can be set in the range of 5 – 35 °C via the potentiometer on the front cover.
Modbus RTU communication
The measured values are available via Modbus RTU. Settings can be adjusted via Modbus RTU. Download the mounting instruction and consult the Modbus register map for the complete overview.
The enclosure is made of high-quality r-ABS VO (UL94) plastic. This material is flame extinguishing in case of fire, very though and offers good protection against impacts. It offers an IP54 protection against ingress of dust, dirt and water.
