Notes
1. All parameters NOT specially mentioned are measured at 110V/230VAC input , rated load and
25℃of ambient temperature.
2. Ripple& noise are measured at 20MHz of bandwidth by using a 12”twisted pair-wire terminated with a
0.1uf &47uf parallel capacitor.
3. Tolerance:includes set us tolerance,line regulation and load regulation .
Physical size
l Input power cord: AC (L), (N), and earth wire (G)
l Output Red is（DIM+）,Black is（DIM-）
Dimming Operation
1. Output constant current level can be adjusted through input terminal of the AC phase line(L) by connection a triac dimmer.
2. Compatible with Leading edge or tailing edge triac dimmers.
3. please try to use the small power dimmers, which can be accessed to a wider dimming range, high-power dimmer is difficult to achieve the output current to zero.

FAQ
1.How many volts does it take to light a LED?
Answer: Some of the issues that may occur when a dimmer is incompatible with an LED lamp are: Flickering - Lamps will flicker (can also occur if a non-dimmable lamp is used) Drop-out - No light output at the end of the scale. ... Damage or failure - LED driver, circuit or LED is damaged or fails.
2.Do LEDS have a polarity?
Answer: Diode and LED Polarity. Diodes only allow current to flow in one direction, and they're always polarized. A diode has two terminals. The positive side is called the anode, and the negative one is called the cathode.
3.Do these(vt) buzz working with forward edge dimming?
Answer: Actually, we sugguest that our customers usel with forward edge triac dimmer for our 100-130vac VT series. And they work well with forward edge triac dimmer.
Most importantly, there is almost no any buzz during they work with forward edge triac dimmer.
4. What is a high power LED?
Answer:
--High power LEDs are one type of LED that has higher power and brightness and of course are more costly comparing to the small power LEDs.The regular LED rating current is 20mA,basically LED with rating current higher than 20mA can be called high power LED.
5. What is a LED driver used for?
An LED driver is an electrical device which regulates the power to an LED or a string (or strings) of LEDs. An LED driver responds to the changing needs of the LED, or LED circuit, by providing a constant quantity of power to the LED as its electrical properties change with temperature.
