Description :
EDWIN PUMP provide 4EFS Series 4" AC/DC Water filled motor Hybrid Solar Pump . We have 3 choices for control box.
Key features :
1.Permanent magnet brushless frequency conversion water-filled motor Frequency control : Small starting current, great starting power, variable frequency speed regulation, the same power brushless motor is more portable
2. Stable mechanism design : Double inner and outer shielded motor with field-oriented control function. No mechanical seal is used, so it can avoid the water leakage and mechanical seal friction. And the wet rotor cooling effect is better.
3. Built-in intelligent controller.
4. Hybrid powered by AC and DC, max power is 3KW
5. Soft start : extend the service life.
6. Voltage range : 60-380VMP or 90-240VAC, 50/60Hz. Max. VOC is 440V
7. Special consideration is given to the aspects of Dry-running protection, Reverse protection, Over-load protection, Over-current protection, Over-voltage protection, Phase loss protection.
8. 304 Stainless steel material : It is made from high-quality materials that are resistant to corrosion and rust.
9. High temperature copper coil , use vacuum dip paint insulation treatment process .
10. High-accuracy rotor with graphite bearing and thrust bearing : The advantages of graphite bearings are mainly manifested in: self-lubrication, high temperature resistance, corrosion resistance, light weight, etc
11. In DC mode, the MPPT can be more effective, even up to 99%
12. In AC mode, the power factor exceed 0.99 in case of power factor correction function
13.Dive deeper : Submerging depth can reach 150 meters.
