AD22 Indicator lamp
Brief description:
AD22-22-25-16 (LED) and AD22-22-25-16-12 (NEON) series of indicator is equally used LED shining chip as light source.
Because of long life, low consumption, small volume and light
weight, it is a product replaced the older generations XD all kinds
of indicator lamp and indicator of neon lamp by new ones.
AD22-25, AD22-22 and AD22-16 indicators produced by our
factory have following character: high brightness,good reliability,
beautiful shape and careful manufacture. Products are well
praised by lots of clients. In order to fit in with quality and demand of user, we develop AD22-22B,C,D,E,G,H,double-color
lamp,position indicator, shining buzzer and mini short indicator
again and use AD22-22G/22GS series button style to design shape,
and it is possible to seal all kinds of international standard symbols
or make to order ones in lampshade. Lampshade is made of
polycarbonate with high intension and has better anti-surge
performance, set up bolt-type connector in it, which will be safer
and more convenient. All improvement will be provided convenience
and perfection for you.
USE:
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.
Advantage:
1) Environmental temperature:-25°C~+55°C.

Main technical data:
1)Voltage of working frequency :2.5KV(AC valid value),1 min.
2) Insulated resistance >2M
3) Voltage wave allowed by AC indicator 20%
4) Continual working life 30000h
5) Brightness 60cd/m2
6) Index of leakage CT1 100
7) Protection grade IP65, and it is possible to be made to order IP67
3)8) Using frequency AC50~60Hz
