Product Description
The 20Y automatic pump control panel is specially designed for 1-phase single home water pumps (0.37-3KW). The most significant feature of the 20Y smart control unit compared to similar ON/OFF units is its ability to operate without level electrodes or floaters if desired. It provides sensitive protection against dry running and is suitable for all situations involving the operation, control, and protection of smart submersible and surface pumps.

Frequently Asked Questions
1. How do I convert HP into KW for my pump?
The formula is 1HP = 0.74KW. For example, a 3HP pump is approximately 2.22KW.
2. How should I choose the power rating for the controller?
It is recommended to choose a controller with a higher power rating than the pump. For a 4KW pump, a 7.5KW controller is often preferred. Please consult for deep well submersible pumps specifically.
3. Does this controller protect against dry running?
Yes, the 20Y model features highly sensitive dry-run protection and does not necessarily require external float switches or probes to detect this condition.
4. Can I request OEM or ODM production?
Yes, customized orders can be fulfilled according to detailed technical requests.
5. What is the typical lead time for orders?
Sample orders usually take 3-5 days, while bulk orders typically take 15-20 days.
6. What happens if there is a power failure?
The controller is equipped with an automatic restart function once the power failure recovery occurs and the voltage returns to a normal rating.
