1. Why does the indicator light still glow after the control power supply has been disconnected?
This situation is caused by the presence of interference voltage, and this problem can be solved by ordering our anti-interference indicator light
2. What are the operating hours of the AD16 series indicators?
>30,000 hours
3. Can the AD16-22 series indicators be produced in ultra-short versions?
Due to heat dissipation, ultra-short types cannot be produced with DC220V and above voltages
4. Is there an indicator with IP67 protection?
The AD16-35KTKA and AD16-60KTKA indicators are IP67 rated
5. What is the sound frequency of the AD16 series buzzer?
AD16-16M:2300Hz±300 / AD16-22M:4000Hz±300 / AD16-30M:3300Hz±300
6. Does the AD16-16 series have a flash buzzer?
Yes, there are two types: plug-in type and screw wiring type
7. How to wire the AD16-22D bi-color lamp?
"X0 is the public end, regular red and green, X0X1 controls the red light, and X0X2 controls the green light. When using AC specifications, pay attention to the directionality of the wiring to avoid burning. "
8. Can the AD16-22SM flash buzzer be controlled separately from sound and light?
Yes, the regular model has a rear endnote-V, X0 is the common end, X0X1 controls the flash, and X0X2 controls the sound
9. Can the AD16 monomer indicator achieve three light emitting colors?
"AD16-22D/rg two-color lamp can be realized, if the red light and green light of the two-color lamp are energized at the same time, the red-green-yellow or red-green-orange color can appear after color mixing"
10. Can the AD16-22M buzzer be waterproof?
No, because the sound needs to be transmitted through the sound hole in the end cap of the buzzer
11. What does FD stand for?
FD stands for discharge lamp that can be installed in a capacitor bank, and AC/DC products are selected for use in capacitor discharge circuits. It has now been cancelled and can be replaced directly with a DC specification indicator
12. Can the DC voltage of the AD16 series indicator be used for AC?
DC stands for Direct Current, which can be used for AC
13. Can the AD16 series indicator be customized to IP67?
No.
14. Can the AD16-22 series indicator be used for Φ25 perforated panels?
Yes, no accessories are required. If the customer wants to fit the hole more perfectly, you can also add a Φ25 reducer ring.
15. Which products in the AD16 series indicators are UL listed?
Currently, only the AD16-25 (R25T) lamp has UL certification
16. What is the reason why the indicator voltage is disconnected, but the light is shining?
The LED chip has low energy consumption, low glow voltage, and the indicator light will be on when there is an induced voltage in the field. To avoid this, anti-interference products can be used.
17. Can the AD16 series indicator beads be replaced?
No.
18. What are the types of AD16 series indicators?
According to the opening size, there are three types: 22.5mm AD16-22 series, 16mm AD16-16 series, 12mm AD16-12A series
19. Can the AD16 AC indicator be used for DC? What will be the impact?
The AC indicator cannot be used for DC and will burn out the indicator. Under normal circumstances, the moment the DC power is turned on, it will be very bright, and it will be dimmed instantly, because the internal capacitance is broken down, but it may be that the LED has not been burned out, so it can maintain a little residual brightness.
20. What is the maximum and minimum voltage of the AD16-22 series indicators?
The minimum AC/DC5V, the maximum AC/DC500V
