-

Driver will adjust the pulse width modulation to one of

four settings: 100 %, 75 %, 50 %, or 25 %

driver: vLsL3-dU

The LED Driver board provides power to one or two panels. It provides a constant current source to up to 8 strings of 6 LEDs.

A 12-V DC source is required to power the driver. The board features undervoltage and overvoltage protection. The driver’s

operating temperature is from – 40 °C to + 105 °C. Every component on the board is AEC-Q101 qualified and, where possible,

sourced from Vishay. Each kit comes with one driver module.
