HEA-P series spring return electric actuator is designed for fail-safe positioning of valves or dampers upon loss of supply voltage .Mechanical spring return design is used to position controlled devices to either fully open or fully closed positions without any external power source.
Torque Protection
A sensor serve as overload protection for the entire valve travel, and you can setting a different torque volume between 40~120% of rated torque.
Limit Protection
Set this function is avilability, the actuator should stop automatically while the valve position reach the limit position.
Automatic Phase Ratation Correction
Actuator monitor the phases and run in the correct direction regardless of the sequence of power supply connection that is realized through a phase rotation correction Boolean logical calculation.
Without this function it may damage the valve in unconsciously.
Main Technical Characteristics
1.The input voltage range:single Phase 50/60Hz:110,120,220,230,240V 3-Phase 50/60Hz:200,230,240,380,400.415.440. 460,480V
2.Using the absolute encoder, the valve position never lost.The absolute encoder can ensure the high precision, zero wear, long life, strong anti-interference, no battery support.
3.Optional all electronic torque detection technology to realize the torque continuous measurement, the over torque value can be adjusted without secondary calibration, it is unnecessary to consider mechanical wear.
4.Perfect bus supporting plan: Profibus dp. Modbus, FF, Hart, Device Net five kind of bus available.
5.Unique double speed control mechanism, can make the actuators in work process avoid causing fluid surge effect.
7.Infrared setting device and knob (magnetic isolation technique) all can set working parameters, convenient and practical, truly realize free open cover.
8.Perfect level 3 password protection, but to different customers or operator separate authorization, prevent fault parameters set to actuator fault phenomenon.
9.Provide five field programmable non-hold type relay feedback, provide an alarm non-hold type relay feedback, extensible four hold-type relay feedback.
10.Input /output signal channel have been photoelectric isolation (can bear 2000 V surge voltage).
11.Operating temperature range: -30C -+70 C.
12.Use humidity range or less 90% RH, non-condensing around, do not contain strongcorrosive, fammable and explosive gas or dust.
