Reinforced high-strength aluminum alloy, fast speed, life of more than 1 million times, stable work, smooth operation Microcomputer controller, more intelligent - multiple sets of transistors are added inside the controller, and a set of protection switches can stabilize the voltage. Universal voltage is widely used - put the transformer function directly in the controller, Multifunctional interface - can be connected with electronic locks, access control systems, etc., and can be directly connected with sensors. The remote control distance can reach more than 10 meters, and the automatic door can be adjusted flexibly (automatic, normally open, normally closed, half-open)., Manufacturer: MNMIOIO
