Applications:

The TE-25A Triac Constant Current LED Driver is suitable for
various applications including downlights, spotlights, and
decorative lighting. It can be used in office, commercial, and
domestic settings, as well as in hotels, classrooms, warehouses,
healthcare facilities, retail outlets, and displays. The driver is
also ideal for retrofit upgrades and new luminaire designs.

Product Usage Instructions:

Triac Dimming Input:

When connecting the driver with a Triac dimmer (such as Lutrom,
Clipsal, or Dynalite dimmer), please note that different Triac
dimmers from different suppliers may have different minimum dimming
levels. The driver cannot be dimmed below this minimum level. To
achieve a dimming level of 1%, ensure that the dimmer supports a
minimum dimming level of 1%.

AC Push-Dim Input:

The driver includes an AC Push-Dim interface, allowing for
simple dimming using commercially available non-latching
(momentary) wall switches. The following actions can be
performed:

• Short press: Turn on or off the light.
• Long press (1-6 seconds): Press and hold to achieve step-less
  dimming. With every other long press, the light level goes in the
  opposite direction.

For any further assistance or information, refer to the provided
user manual (Version 1.0.4).

Triac Dimming Input

TE-25A Triac Constant Current LED Driver

While connected with a Triac dimmer, such as Lutrom, Clipsal, Dynalite dimmer, different Triac dimmers from different suppliers may have different minimum dimming levels which the driver can not be dimmed below. To dim to 1%, please make sure the dimmer supports 1% minimum dimming level.
AC Push-Dim input
The provided AC Push-Dim interface allows for a simple dimming method using commercially available non-latching (momentary) wall switchs.
Short press: Turn on or off light.
Long press (1-6s): Press and hold to step-less dimming, With every other long press, the light level goes to the opposite direction.
Dimming memory: Light returns to the previous dimming level when switched off and on again, even at power failure.
Synchronization: If more than one LED driver are connected to the same push switch, do a long press for more than 10s, then the system is synchronized and all lights in the group dim up to 100%. This means there is no need for any additional synchrony wire in larger installations. We recommend the number of LED drivers connected to a push switch does not exceed 25 pieces, The maximum length of the wires from push to LED driver should be no more than 20 meters.
