LiftMaster RSL – Slide Gate Operator

Residential / Light Commercial Slide Gate Operator with Battery Back-up

The RSL12V is our most advanced residential and light commercial pad mounted slide gate operator. It features a powerful DC motor with soft start/stop operation for quiet and reliable performance, and is rated for gates up to 800 lbs. and 25 ft. in length and cycling up to 120 times per day.

In addition to a long list of safety and convenience features, the RSL12V can be distinguished by an innovative control board that offers:

EverCharge® Power Management System
Leading the industry with only 8mA power draw when idle including an on-board radio receiver, this system delivers power when needed most for operating the gate while conserving power at all other times, resulting in more cycles when needed for battery backup or optional solar power.

Exceptional Standby Power
Ten seconds after the gate closes, the system switches off non essential ancillary devices to conserve power. This is critical in the event AC power is lost as the battery backup system will remain operational for days or weeks depending on the daily cycle rate and power draw of accessories connected to the 12V accessory power output.

True Power Management System
Our system will not only recover batteries quicker when discharged, it also manages the low power threshold and will not run the batteries beyond the point of failure ensuring they are ready for the next time they are needed.
