Compact controller features universal input voltage from 100 V AC to 240 V AC for easy installation, a Soft-Start function that helps prevent screw head and thread damage by allowing a slower starting speed and step-less speed adjustment so you can select optimum screw tightening speed for various applications. Rear output terminals allow signals of Start, Torqued-up and Reverse to be used with a counting device to help prevent screw tightening errors. Mount horizontally or vertically. Grounded bit system standard (with a 1MΩ resistor). 50/60 Hz. Compatible with DLV30/45-IKU series drivers.
