High-voltage step-charge control for use in network-powered applications

摘要

An over-current input conditioning limiter is disclosed for remote equipment. The over-current input conditioning limiter includes a current sensing apparatus, a semiconductor switch, and a programmable controller for controlling the peak current drawn from a pair of supply lines. The over-current input conditioning limiter is particularly useful for overcoming voltage collapse and over-current shutdowns of network power supplies feeding remote apparatus known in the art.
