MULTICHANNEL SOURCE OF SINGLE-POLARITY VOLTAGE WITH OVERLOAD PROTECTION Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: current pickup is installed in power bus of centralized converter and is simultaneously placed in succession into each output channel. It has elements normalized in proportion to current. When level of current in any channel increases signal from "current mirror" goes to actuating element and into system of binary-seven-segment decoding with indication of faulty channel through multiplexer. EFFECT: expanded functional capabilities, simplified design and increased reliability of source. 2 dwg
