JS ACTUATORS
THE ACTUATOR SPECIALIST
The Enerdrive System
Power failure can be damaging to equipment, products, livestock and people, especially in tightly controlled environments.
The Enerdrive system incorporates super capacitors to store energy ready to move the actuator to its failsafe position in the event of a power failure.
LD models (16 Nm torque)
This quarter turn actuator may be directly coupled to either a 19 mm round or 16 mm square jack shaft or remotely moun-ted using an adaptor kit.
All motors are bi-directional under power and, in the case of models equipped with the Enerdrive System, under failsafe conditions. The stroke may be limited to less than 90° mechanically in digital models
and electronically in Multi Signal models.
The LD models are available with programable, multi signal, analogue or on/off floating control.
