EC motor 230 V | 3-step fan speed control

This is a 3-step control switch designed to optimise control of EC fan speed, damper actuators, AC fan speed controllers or frequency inverters. The SMT-D-3P-AL offers versatile control, providing three fixed positions that simplify the process of adjusting fan speed. These fixed positions ensure effortless optimization, allowing you to easily find the ideal speed for your specific ventilation requirements. It features adjustable output signals. Positions 1 and 2 offer the flexibility to customise output signals within the 1–10 VDC range, while position 3 consistently delivers the full input voltage of 10 VDC. The SMT-D-3P-AL comes without an OFF position. No need to worry about inadvertently turning off your system; with the SMT-D-3P-AL, it's all about reliability and consistent performance. Designed with durability in mind, the splash-proof enclosure of the SMT-D-3P-AL allows for either inset mounting (IP44) or surface mounting (IP54). This ensures that, regardless of your preferred installation method, the device remains robust enough to withstand various environmental factors.
