Notes

1. All parameters if NOT specially mentioned are measured at 120VAC input, rated load and 25℃ of ambient temperature.

2. To extend the driver's using life ,please reduce the loading at lower input voltage.


Application:

Triac dimmable downlight, dimmable LED spot light, dimmable panel light, dimmable floodlight, dimmable bulb light etc external LED dimmable lights.


Notice for use:

1.The driver must be well-joined to the lamp before connecting to the main power, long time no-load with power on is forbidden.

2.If need to weld power wire, do avoid touching the tin of other welding spot, cold joint, false solder and short circuit.

3.All the wire should be avoided touching the surface of the capacitance directly.

4.When assembling the lamp, please do not press the led driver for fear of deforming or damaging the components.

5.Working environment and temperature must be in compliance with the regulation of the specification.

6.Naked wire or metal housing should be avoided touching the driver directly.

7.Aging test should be conducted according to actual situation for more than 24 hours after the driver assembled to the lamp to make sure the quality of the driver.

8.Try to avoid direct touching between the housing of electrolytic capacitor and the housing of the lamp.

9.All the wire must be heat-resisting wire and should be avoided squeezing.



FAQ

1.Can i get a discount price: 

We can allow you good discount according to your bulk order quantity. 

2.Can you supply EMC test report if we need the led driver must pass EMC?

Yes, we have EMC test machine, if you need led driver EMC pass, we can test and send you full test report.

3. Can you make the led driver cable length as we need?

Yes, we can make the length as your requirement.
