Z-DEFENDER.3 is an innovative electronic panel essential to start, run and protect the three-phase ZDS submersible pump against many possible installation and operation faults. Z-DEFENDER.3 is designed to guarantee an optimal protection of the submersible pump against many possible installation and operation faults: an alarm will be shown on the dispaly in case of current overload, low voltage or high voltage, dry running, phase missing or phase imbalance; ensuring a high degree of automation and restoration. Z-DEFENDER.3 allows to continuously detect and monitor in real time the power: the electrical parameters obtained are processed by a special software, which will efficiently guarantee the correct working conditions.
With Z-DEFENDER.3, the submersible pump can work and be continuously protected also when the supply voltage values are at tolerance limit, providing the effectiveness of the protection operation. In addition, Z-DEFENDER.3, thanks to a “smart software” at variable time and automatic restart, can ensure the optimization of water withdrawal from the borehole or tank when the pump is dry running. Thanks to its special and innovative ZDS technology, Z-DEFENDER.3 combines, in a single device, protection, reliability and ease of installation.
