Electric Potention Meter/Modulo Auxiliar Raise/Lower Governer/Motorized Potentiometer

EP series electric potentiometer is a kind of electric actuators, according to the polarity of the input voltage, drive mini servo motor is forward or backward, to change the size of the output resistance potentiometer.

Our company have many series electric potentiometer,like EP series,MP series,TP series,HP series,SV series.If you have any questions,please do not hesitate to contact us.

EP series electric potentiometer is a kind of electric actuators, according to the polarity of the input voltage, drive mini servo motor forward or backward, changing the size of the output resistance potentiometer
This series of electric potentiometer has the following characteristics:
1, potentiometer value is adjustable from zero to the maximum according to the model, compared with the traditional way of limit switch protection, the adjusting range is bigger.
2.Through the limit of maximum output torque, flow control motor to prevent the damage caused by a torsion motor and potentiometer. Compared with the traditional way of limit switch protection, more simple, reliable and easy to maintain.
3.Adopts draw-out type structure, small size, light weight. Installation and disassembly are easy and convenient.
4.Selects the import high performance wear resistant ring potentiometer, service life is longer, more fine adjustment, meet with the strict requirements of automatic control.
5.The input power is small, easy to control, especially suitable for use in remote control and automatic control.

When working, external DC24V via control circuit board processing to servo electrical control signal. Machine, according to the polarity of applied voltage signal, to change the positive and reverse motor, thus promote potentiometer shaft forward or reverse, change the output resistance.

Resistance change law is as follows:
No.1 connect DC24+,No.2 with DC24-;between 4-5 R increasing,5-6 R reducing
No.1 connect DC24-,No.2 with DC24+;4-5 R reducing,5-6 R increasing

When in severe vibration situation, should take appropriate measures of vibration reduction. Installation of the product accompanying shock absorption block can effectively reduce the vibration
environment temperature<45ºC.
In such as steam and high condensate fog air humidity, should have appropriate protective measures.
