This switchmode driver will run three 1 watt LEDs in series at 320mA from a 12 volt DC source or 6 LEDs from a 24 volt source. The driver uses the common and very efficient '350' LED driver and a 35 volt input capacitor, so it should handle higher voltages and more LEDs, providing the LED string voltage is less than the input voltage by a volt or two. Driver measures 25mm x 20mm x 12mm.

These great little digital LED panel meters are fully potted and waterproof and can even run under water! They are ideal for anywhere you need a panel meter that will stand up to the elements, or just where you want something a bit more rugged than the average meter.
