AD22 series of indicators are used as indicating, foretelling,accident and other signals in the lines of equipment (such as electrical power, telecommunication, machine tool, watercraft,textile, printing, mine machinery, etc).
Working environment
1) Environmental temperature:-25ºC~55 ºC
2) Relative humidity: <98%.
3) It can normally work under following condition: vibration
frequency is 2-80Hz and accelerated speed is 0.7g.
4) Pollution grade is 3
5) There is a "TH" sign, and it is possible to work under the moist tropical environment.
Main technical data
1) Voltage of working frequency: 2.5kV(AC valid value), 1 min.
2) Insulated resistance > 2MΩ
3) Voltage wave allowed by AC indicator -: 20%
4) Continual working life B 30000h
5) Brightness > 60cd/mz
6) Index of leakage CT1 > 100
7) Protection grade IP65, and it is possible to be made to order IP67
8) Using frequency AC50-60Hz
