3810/3410 Electric Actuator

What is a 3810/3410 Electric Actuator?

3810, 3410 series electronic type electric actuator, using 220V AC single-phase power as drive power, that is a safety electric actuator accepting computer controller or operator 4-20mADC or 1-5VDC input signal to operate. Its inside has a servo system, no need spare servo amplifier. Key part “ controller “ adopt advanced hybrid integrated circuit, and use resin to solid-cast. After ageing treatment, moistureproof , shockproof. Positioner adjust zero , trip , sensitivity conveniently. Function switch can choose direct action, reaction, choice stop signal three situation. Meanwhile, the actuator has overload protection, temperature protection and compressed spring protecting valve close completely. It is a highly reliable product, with a straight trip and angle trip consist of the electric control valve.
