FIELD: electrical engineering.
SUBSTANCE: invention relates to LED indicators. Said indicator contains a transformer, full-wave diode rectifier, a capacitor, the first and second sources of stabilized voltage, n (where n≥1 is the number of decimal digits of the multi-digit indicator) of seven-segment indicators on LEDs with a common anode, n information inputs, which are information inputs of n decoders from a binary-decimal code to a seven-segment code, a variable resistor.
EFFECT: technical result is to simplify the indicator and reduce power consumption.
