Power management device for large electronic flash units
First Claim
1. A power management device for managing a single power supply to a plurality of electronic flash units which limits the electrical current demand on an AC main single power supply following a simultaneous discharge of the plurality of electronic flash units, comprising:
- a power supply input connecting said power management device to an AC main single power supply;
a synchronization circuit for detecting simultaneous flash discharge of said plurality of electronic flash units;
a plurality of service outlets for providing electrical power to each of the plurality of electronic flash units; and
an electronic timing circuit interfaced between said power supply input and said plurality of service outlets, said electronic timing circuit immediately disconnects said plurality of service outlets from said power supply input when said synchronization circuit detects the simultaneous flash discharge and thereafter reconnects said plurality of service outlets to said power supply input in a timed delay sequence, thereby limiting the electrical current demand placed on the AC main single power supply.

Abstract
A device for controlling the surge of electrical current demanded following the discharge of a lighting system comprised of multiple electronic flash units powered from a common source. Individual electronic flash units are re-charged sequentially by the invention after system discharge, thus limiting the current demand to approximately the level produced by a single strobe light apparatus. The power management device for large electronic flash units can be integrated into the circuits of a strobe light apparatus, a generator, inverter or battery pack itself, or it can be configured as a self-contained accessory device.
