Major Features

Light weight
AL base and plastic cover, light weight, small space, big output torque. Al cover is
Rubber seal between cover and basement to provide good waterproof function.
Can be installed outdoor.
Planetary gear
Internal gear combines planetary gear, turbine worm drive for manual
operation. Having good self-locking function.
3D indicator
Special plastic material with long life. 3D indicator function creating 360
visual angle.
Multi-power input Either
AC24V or DC24V power is allowed.
Manual operation
EFM1/A needs extra 8# wrench. EFM1/A/B-H with hand-wheel manual
override, without clutch.
When power failure occurs,actuator position mode can be preset to "totally open",
"totally close", and "remain unchanged".
Super capacitor
Maintenance free, no memory effect, short charging time, can change continuously
500,000 times, lifetime can reach 10 years. (Can be used in the environment less
than 65°C)
High performance lithium
Using imported rechargeable lithium batteries, with large capacity, long life, and
