SKZ serial motor operator

SKZ serial electric actuator is a new-generation mechanical & electrical integration product. Control unit is composed of chip microprocessor and peripheral chips to receive standard signals; after CPU oper ates and treats, it directly drives the displacement of control valve. The installation size and torque are equal to the former standard model, and the users have no need to design size. The serial electric actuators are widely used in electricity generating, metallurgy, petroleum, chemical, and light indus try, etc.

Characteristics

●Equipped with input signal wire and single-phase ac power supply, it can be operated without servo amplifier.
●Regulation can be realized by operation panel without opening cover, simple and easy to understand.
●Four high-brightness LED nixietube displays operation state and alarm information correctly and clearly.
●Control process has in-off signal setting function.
●Position transmitter adopts gear drive to ensure the reliable and accurate limit.
●Circuit adopts modular structure sealed by epoxy resin after low-temperature aging process to ensure stability and reliability.Model descriptionsSKZ-310 (H)SK: mechanical-electrical integration type Z: linear motion 310: output powerH: with H--outdoor type; no H--standard type (options)
