  Mechanical Specification  


 12 volt transformer for led lights


Ø Input terminals "Black" and "White" to connect to AC L and N.

Ø Output LED SEC output Positive (LED+) , output negative(LED-). Connected to LED light.

Ø Output terminals DIM (+) to 0/1-10V dimmer signal(+ ),DIM (-) white connect to 0/1-10V dimmer signal (-)

Ø Please DO NOT connect “DIM-“ to “LED-“, “DIM+” to “ LED+” ,or other incorrect connection.

Ø Please make sure your connect these correctly otherwise your product will not function correctly and could be damaged.

 

  Derating Curve  


electronic transformer for led lights  

Ø Load carried in accordance with the load derating curve, according to the ambient temperature derating, in order to extend the service life.  


  Dimming Operation and Connecting Diagram  


1.  Using two ways of dimming at the same time

customers should be assured that LED lighting is up to the max. Brightness then you could operate with the other dimming;

 2.  Using one dimming ---TRIAC/Phase cut dimming 

Ø The Pulse-Width Modulation (PWM) of output voltage can be adjusted through input terminal of the AC phase line(L) by connection a phase /Triac dimmer of lighting system.

Ø Working with forward phase /leading edge ,MLV and Reverse phase /trailing edge ,ELV,TRIAC dimmers 

Ø Min loading is about 10%

Ø Please try to use dimmers with power at least 1.5 times as the output power of the driver.
