UL 24v Triac dimmable dc constant voltage led driver supplier 24W 30W 45W
SMT-024-045VT is triac dimmable UL led driver, plastic case IP20 requires to work in indoor applications, note to give mininum 60% load ( 27w) to this dimmable driver 45w to reach a smooth dimming, or it will have flash problem, Max. load around 90% is optimal.

Notes
|
1. All parameters NOT specially mentioned are measured at 120VAC,220VAC 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 .

What is the Factors that will affect Inrush current in a led driver ?
Instantaneous inrush current is related to input voltage, load capacity and current surge time to a led driver. we have show this rate to the datasheet of each our dimmable led driver 12v 30w to 300w, constant current and constant voltage led drivers, kindly refer to our online datasheet or contact us to get more details.

Connecting diagram:
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 dimmer, have access to a wider dimming range, high-power dimmer is difficult to achieve the output current to zero.
