11What does FD stand for?
FD stands for discharge lamps that can be installed in capacitor cabinets. When selecting products, choose products compatible with both AC and DC, which can be used in capacitor discharge circuits. It has now been discontinued and can be directly replaced with indicators of DC specifications.
-
12Can the AD16 series indicator with DC voltage be used for AC?
DC stands for direct current, and they can be used with AC.
-
13Can the AD16 series indicators be customized to IP67?
No, they cannot.
-
14Can the AD16-22 series indicators be used on a panel with a Φ25 hole?
Yes, they can be used without the need for additional accessories. If customers desire a more perfect fit with the hole diameter, a Φ25 adapter ring can also be installed.
-
15Products in the AD16 series that are UL certified?
Currently, only the AD16-25 (R25T) indicators are UL certified.
-
16The indicator voltage has been disconnected, but the light is still on. What could be the reason for this?
LED chips consume lower energy and have a low turn-on voltage. When there is induced voltage present on-site, the indicator will light up. To avoid this phenomenon, anti-interference products can be selected.
-
17Can the lamp beads of the AD16 series indicators be replaced?
No, they cannot.
-
18Types of AD16 series indicators?
Three types categorized by hole size: the 22.5mm AD16-22 series, the 16mm AD16-16 series, and the 12mm AD16-12A series.
-
19Can the AD16 AC indicators be used with DC? What would be the effect?
AC indicators should not be used with DC as it can damage the indicator. In general, when DC power is applied, the brightness will be very high at the moment of connection, and then it will quickly dim due to the internal capacitor being breached. However, it's possible that the LED may not be completely burnt out, allowing it to maintain a slight residual glow.
-
20Maximum and minimum voltages for the AD16-22 series indicators?
Minimum AC/DC 5V, maximum AC/DC 500V.
