Description
Gas-discharge indicators IN-12 are used in calculating devices, in various measuring instruments and other discrete-action equipment, for visual presentation of output data. IN-12B differs from IN-12A by the presence of a dot.
Technical specifications:
- Power supply – at least 200V
- Occurrence of discharge – no more than 170V
- Maintaining the discharge – no more than 150V
- Digits – no more than 2mA
- Comma – no more than 0.3mA
Operating current when powered from a DC voltage source:
• digits – from 2mA to 3.5mA
• comma – from 0.3mA to 0.7mA
Operating current when powered from a pulsating voltage source:
• digits – from 1mA to 2mA
• comma – from 0.15mA to 0.2mA
- The brightness of the IN-12 tube is at least 100cd/m²
- Viewing angle – at least 45°
- The height of the digits is 18mm
- Overall dimensions – 21 ×35mm
Operating time – at least 7500 hours.
