SU1325430A1 - Alternating voltage stabilizer - Google Patents

Abstract

The invention relates to secondary power sources of radio equipment. The aim of the invention is to increase the reliability of the variable voltage regulator. The goal is achieved by the fact that when any output parameter deviates from the specified value, threshold element 3 issues a fault signal to the optoelectronic switch 4. Display elements 5 reveal the type and location of the fault in the load. The signal from key 4 through the element OR 6 blocks the signal from AND elements 15 to the switching elements 16. Load 2 de-energizes. After elimination of the malfunction, the stabilizer is switched on automatically. 1 il. (L
