Overvoltage protection - Import export

This circular motorised damper is suitable for ducts with 125 mm. The position of the damper blade can be set via Modbus RTU communication or a 0-10 V signal. The enclosure has an airtightness class D according to EN1751. To ensure this classification aluminium tape should be wrapped on the seam between damper/duct. The unit needs 24 VDC supply voltage. We recommend using Sentera 24 VDC power supplies with RJ45 connector. They are protected against overload, overvoltage and short circuit. Once installed the device is ready for use. The default settings will suffice for most applications. If you do need to change some parameters, this can be done via Modbus RTU communication.
