Why line-voltage?
- Simpler installs: no DC power supply or transformer to buy, mount, wire, or troubleshoot
- Fewer failure points: the power supply is the most common failure in DC actuator systems — this system doesn't have one
- Electrician-friendly: standard 120VAC wiring practices; no low-voltage runs
- Pairs with our panels: order it with an SES control panel and remote station as a complete, bench-tested motorization kit
