- power supply - not less than 200 V;

- discharge occurrence - no more than 170 V;

- maintaining the discharge - no more than 170 V.

Working current:

- when powered from a constant voltage source - from 2.25 mA to 3.75 mA;

- when powered by a source of pulsating voltage (average value) - from 1 mA to 2 mA.

Indication current - no more than 2.5 mA.

The brightness of the IN-15A indicator lamp is at least 100 cd/m2.

Viewing angle - not less than 60°.

Operating time - not less than 5000 hours.

Cathodes - in the form of signs and letters.

The time delay of ignition of the discharge in the light is no more than 1 s.

Decoration - glass.

Ambient temperature - from -60° С to +70° С.

The height of the sign is 18 mm.

Overall dimensions - 21×35 mm.

Weight - no more than 20 g.

Indicator IN-15A is characterized by high brightness and image contrast, low power consumption, simplicity and reliability. It fills with neon and has an orange-red glow. The indication is made through the cylinder dome.
