9913 "Swift" Coil Economizer Has Other Uses
Our Swift coil economizer is a work horse that has a lot of other uses. It is essentially a DC to DC converter with some special fast drop out features that provide the current required to operate a contactor over a wide voltage and temperature range. It was originally designed to be molded into and work with our EV250 contactor.
It also has a built-in feature (which can be easily modified by the user) that allows the EV250 contactor to be turned on by a logic level signal (TTL or CMOS). This option can save you a lot of engineering time, money, board space, and reduce the complexity of your system. However, this feature is not available when the economizer is molded into the EV250-2A case because it requires a third pin for the TTL control.
If you have an application where this logic control feature would be desired, we can add a three pin coil connector to our EV500 for a one time charge of about $10,000.
Another application for Kilovac's "Swift" coil economizer is to control the coil of any electrically held (commonly called "fail safe" or "non-latching") Kilovac relay where:
- Logic level (TTL or CMOS) coil control is required, or
- Where the relay must operate over a wide coil voltage or temperature range, or
- Where minimum coil power consumption is important
We can adapt our "generic" swift coil economizer to match the coil power requirements of the Kilovac relay it will be used with. This can be done for 12 Vdc systems today, and 24 Vdc systems in the near future.
