FC-ERV3

Controlling fan speed, pump flow or ventilation volume in commercial and industrial systems often means dealing with bulky throttles, variable resistors or inefficient motor runs. The FC-ERV3 solves this by providing a compact, selectable-mode electronic speed controller tailored for single-phase motors up to 3 A at 230 V. With input from a BEMS or analog signal source (0–10 VDC / 0–20 mA) you can regulate fan or pump speed to match demand rather than always running full-tilt. The unit supports both kick-start mode — briefly applying full voltage to overcome inertia — and direct control mode for gentler startups. It includes internal trimpots and dipswitches to set minimum and maximum motor voltages, enabling customised range limiting and off-level behaviour. The IP54 sealed wall-mounted enclosure delivers protection in typical mechanical rooms, plant rooms or HVAC zones. Compared to fixed-speed motors or resistive control methods, the FC‐ERV3 offers smoother performance, quieter operation, less wear, and lower energy consumption. For your fire service, home automation or parking-system applications (via your MSI Agency services), this means quieter ventilation, smoother variable-volume control and smarter integration into building automation systems — delivering professional-grade motor control without complex variable-frequency drives.
