TGP550-AC/DC
Functional specifications:The AC permanent magnetism motor has high efficiency and can save electricity by 10% at the same performance. Wide voltage range:AC Voltage Range:From 150V to 260V.Both 50Hz and 60Hz are available.DC Voltage Range:From 210V to 360V.The best efficiency requests voltage:220V(AC) or 310V(DC).
Under voltage protection
When the Ac voltage is below 150V or Dc voltage is below 210Vthe pump will stop working automatically. It can work automatically when the voltage restored (AC is higher than150V, DC is higher than 210V).
Over voltage protection
When the Ac voltage is higher than 260V or the DC voltage is higher than 360V, the pump stops working automatically. It can work automatically when the voltage is restored (AC less than260V, DC less than 360V).
Thermal protection
The motor will get heat when the pump is running. when the temperature of motor and controller are higher than 85'c, the pump will automatically stop working.(when the temperature is below 45'C ,the pump will be back to normal)
No load protection
If there is no water in the inlet pipe , the pump will stop working after 1 minute to prevent energy waste from pump dry running.
Lock up protection
When the pump is jammed, the pump stops running automatically to avoid pump being damaged. After the dead object is removed the pump can be operated again.
