Power Conservation Schemes
Quite often in space, aircraft, or battery operated applications it is important to minimize relay power consumption either to conserve power or to minimize heating. Kilovac offers three ways to help you reduce the power which must be dedicated to supply the relays.
- Use a latching relay. Latching relays need only to be pulsed to switch. Power can be removed and the relay will maintain its latched position. If a normally open or normally closed relay must be used, Kilovac has developed a custom hybrid circuit which allows a latching relay to function as a non-latching relay.
- If a latching relay is not available for your application, Kilovac may be able to incorporate an "energy conserving" circuit in your relay package. This circuit regulates the power provided to the coil, providing full power during relay operation and providing a reduced power level which is adequate for holding the relay contacts in position at other times. An energy conserving circuit such as this must be custom designed for each application and each model relay. Contact the factory or your local Kilovac Sales Representative for more information.
- For failsafe contactors, Kilovac offers electronic economizers for reducing coil power once the contacts are closed. These schemes result in more energetic activation, smaller size contactors, and substantially reduced coil temperature rise.
