Abstract:
A remotely powered device comprising: (a) input terminals for receiving available input power from a remote power source; (b) a load element coupled to said input terminals, said load element consuming at least a portion of said available input power received by said input terminals and generating a load power demand; (c) an input capacitive device coupled to said input terminals for providing transient bypass for said remote device; (d) an energy storage device coupled to said input terminals, said energy storage device being configured to store at least a portion of said input power and to supply stored energy to said input terminals; and (e) a pump device coupled to said input terminals and to said energy storage device, said pump device being operative to cause said energy storage device to store at least a portion of said input power when said input power level is above a first threshold level, and to cause said energy storage device to supply energy to said input terminals when said input power level is below a second threshold level.
