SURGE PROTECTED DEVICES AND METHODS FOR TREATMENT OF WATER WITH ELECTROMAGNETIC FIELDS
Devices for treating water are provided with a varistor to protect the circuitry within such devices against excessive voltage surges and/or transient voltages. The varistor is incorporated into the circuitry in such a way that, when triggered by a high voltage spike (e.g., power surge), the varistor shunts the current created by the high voltage spike away from other sensitive components of the circuitry. Methods for treating water using devices that incorporate the varistor are also provided.
1 . An electromagnetic field generator comprising:
a varistor operable to shunt current created by a high voltage spike to protect circuitry components configured to generate static and varying electromagnetic fields within water.
2 . A method for protecting circuitry components comprising:
connecting a varistor to circuitry components configured to generate static and varying electromagnetic fields within water; and
shunting current created by high voltage spikes using the varistor.
