Questions answered in these manuals
What is the input voltage range for this LED driver?
The device accepts an input voltage ranging from 90 to 265 V.
What constant current does the board provide for LEDs?
The driver provides a constant current of 350 mA for LEDs.
What is the output voltage of this driver?
The circuit generates about 10 V.
How many LEDs are in the load?
The load is composed of three high-brightness (HB) LEDs, connected in series.
What is the main advantage of the VIPer22A for DVD power supplies?
