120VAC line-voltage
SES LA-300H Linear Actuator — 120VAC High-Force
Line-voltage linear motion. No power supply. No transformer.
Most linear actuators run on 12 or 24VDC — which means every installation needs a power supply, a transformer, and a low-voltage wiring run before anything moves. The SES LA-300H wires directly to 120VAC line power. One cable, standard breaker, done.
Every unit is specified by our engineering team, individually bench-tested in our Connecticut shop before shipment, and backed by an engineer who answers the phone.
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
