Description :
EDWIN pump offers 4/6EFS series 6 6" AC/DC Water Filled Hybrid Permanent Magnet Brushless Solar Pump. We have 3 choices for control box .
Key features :
1. Permanent magnet brushless frequency water-filling motor : Reduce friction ,small starting current and great starting power
2. Stable mechanism design : Dual internal and external shield motor, with field orientation control function.
3. Built-in intelligent controller : Adjustable with the amount of water, and has a hard shell to protect the controller
4. Ac and DC hybrid power supply the maximum power reach 3KW, both throttling and high efficiency.
5. Soft start : With effective control, the pump will not spray water instantaneously to make the motor run longer.
6. Voltage range : 60-380VMP or 90-240VAC, 50/60Hz. The Max VOC is 440V
7. Special consideration is given to the aspects of dry-operation protection, reverse protection, over-load protection, over-current protection, over-voltage protection, lack of phase protection.
8. 304 stainless steel : It is made from high-quality materials that are resistant to corrosion and rust
9. High temperature copper coil : Strong corrosion resistance, not easy to oxidize.
10. High precision graphite bearing and thrust bearing rotor : The advantages of graphite bearing are mainly manifested in: self-lubricating, high temperature resistance, corrosion resistance, light weight, etc.
11. In DC mode, the MPPT function carries out more than 99% efficiency.
12. In AC mode, power factor correction function can make the power factor exceed 0.99.
13. Dive depth up to 150 meters.
14. 2-year warranty
