Sun Switch
€230.00
The LORENTZ SunSwitch is designed for use with the LORENTZ pump controllers. It can also be used for any application where you need to switch de- pending on solarlight intensity. It is an autonomous working unit that supplies itself with power from the solar cells on its rear side. It is environmentally protection rated to IP54.
Information
Some solar pumps (e.g. centrifugals) are only effectively pumping water when a minimum solar irradiation is avail- able. When there is not enough irradiation, the pump starts to rotate but does not deliver any water. In this case the pump can heat up and wear off prematurely.The SunSwitch can also be used with appropriate relays to switch on a mains power pack to provide a constant power source in pumping applications where minimum flow re- quirements need to be met 24 hours per day. An example of this would be for commercial swimming pools where constant turnover of water is required 24 hours per day. The SunSwitch will activate a power supply when the solar energy is not sufficient to provide the required water flow rate.
The Advantages
- reduced wear on the pump and motor since the pump only starts when it will continue to run;
- no water heat up inside the pump due to too insuf- ficient power in low light situations where the pump spins but cannot produce a flow up to the delivery point; and
- pump will only run when minimum flow rates or pres- sure levels can be achieved which are required by cer-tain applicators.
