IQM - Multi-turn Modulating
The modulating version of the IQ 3-phase electric actuator has a solid state reversing starter in place of the electro mechanical contactors. It features fast-response remote control circuits for rapid control. To optimise positional control, the solid state starter also adds an electronic motor ‘brake' feature.
The IQM is suitable for up to 1,200 starts per hour (S4 / Class C). Direct seating torque output range from 10 to 544 Nm (7 to 400 lbf.ft). With second stage gearboxes, output seating torque up to 3,600 Nm (2,655 lbf.ft) and part-turn up to 77,000 Nm (56,790 lbf.ft).
