Zusammenfassung:	FIELD: electrical engineering. SUBSTANCE: device has two voltage limiters 3, 4 interconnected in series opposition and inserted between conductors 1, 2 passing supply voltage to radio electronic device. Novelty is that light-emitting diode circuit is connected between junction point of voltage limiters 3, 4 and conductor 2 and fusible jumper is connected in series with voltage limiter 3 to form protective circuit. So, device is capable of indicating failure of voltage limiter 3 or 4 as well as voltage failure across supply mains. EFFECT: improved reliability of radio electronic devices. 2 dwg
