SuperCap Fail-safe Electric Actuators / DM Series
Product Overview

It uses supercapacitors to drive dampers or valves to a safe position (either fully OPEN or fully CLOSED) when the power supply is lost, which ensures electronic fail-safe positioning. In addition, it features a multi-voltage design, a plug-and-play modular structure, electronic torque limiting, LED status and alarm indication, adjustable travel, and support for floating or modulating control.
