The Vortek S Series Controller is designed for slow-moving line sets with heavy loads such as lighting battens or shell ceilings, where movement typically does not occur during performances. It supports basic stage rigging needs with fixed-speed hoist operation across various load capacities. Standard features include a rugged steel enclosure, hard-wired E-stop circuit, power key switch, over-travel indicator, momentary dead-man push buttons, and factory-set over-travel limits. Optional digital position display provides precise position feedback. Electrical specifications include 3-Phase 200-480V AC operation at 50/60Hz with globally available components. Systems are built to order for 1-12 hoists within power limitations.
