This 3-step control switch regulates EC fans, damper actuators, AC fan speed controllers or frequency inverters. It needs 10 VDC supply voltage. The device has an OFF position to stop the motor completely. Thus, the output signal is divided into 4 steps: 0 VDC and 3 other output voltages. The output for position 3 always equals the supplied voltage i.e. 10 VDC. The output ranges for positions 1 and 2 can be adjusted via internal trimmers. There is also a version with 2 predetermined voltage steps: SMT-D-4P-EM

Experiencing excessive vibrations in sensitive mechanical structures or rotating machinery? Tuned Mass Dampers (TMD) and Tuned Mass Absorbers (TMA) provide a simple and effective solution to reduce them. TMA and TMD are mechanical resonant devices used to suppress or absorb vibrations. When installed properly on a machine or structure, they draw away vibrational energy from the structure or machine and dissipate it internally, hence reducing their motion. They do not require a redesign of the target structure/machine and do not interfere with the main structure/machine function. This makes them an ideal solution for existing machine retrofitting/troubleshooting.Whenever alignment and balancing of the rotating equipment has been performed but the vibration level is still too high Excessive structural vibration excitation during ramp-up or slow-down (stirring machine, flywheel, etc.) MECHANICAL STRUCTURES

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.
