Belimo's fast-running rotary non fail-safe actuators come in LMQ, NMQ, NMD, SMQ, and SMD ranges, catering to diverse damper sizes and torque requirements. The LMQ and NMQ models, both with 24V nominal voltages, achieve 90° rotations in 2.5s and 4s, suitable for dampers up to 0.8m² and 1.5m², offering 4Nm and 8Nm torque. The NMD230A model operates at 230V, turning 90° in 20s for 1.5m² dampers with 8Nm torque. For larger applications, the SMQ and SMD ranges provide 16Nm torque for up to 3.2m² dampers, with varying speeds and voltages.
