Abstract:
For use in controlling selective application of electrical load power to a load, a parasitic control system to provide power to a control device from the load power comprising:first means for coupling to a source of electrical load power to be selectively applied to a load; second means for parasitically diverting a predetermined amount of power from applied electrical load power whether or not said load power is applied to the load, said predetermined amount of power being insufficient to impair proper operation of a the load when power is applied to the load or to cause activation of the load when load power is not applied to the load; third means coupled to said second means for providing control device power at a predetermined voltage level to a control device; and fourth means for sensing said predetermined voltage level of said control device power provided by said third means and for activating said second means as necessary to maintain said predetermined voltage level.
