Oil field pumping unit controller

basic function

1. The protector has the function of automatic conversion of the star triangle and the protection functions of overload, phase interruption, blocking and rotation, and the performance is stable and reliable.

2. The protector has manual reset instructions.

3. The protector has action indication function. The protector is broken phase, normal, overload red yellow green indicator lamp and broken phase

The indication can also distinguish the U phase, the V phase and the W phase of each phase, indicating the transition state of the star triangle with memory indication.

4. The external power supply of the protector can work out the power supply specification according to the user's requirement.

5. The protector adopts three phase same direction core way.

6. The protector is electrically separable: normally open normally closed contacts.

7. The setting current can be adjusted from 10A to 200A by dial switch.

8, low power consumption at work, is a new type of energy-saving high-tech products.

9. The protector is triangular when starting.
