OUT

OUT Wire

External LED String

“DC-“ Wire

1. The evaluation can also be configured as High side current LED configuration.

2. Ensure that the DC source is switched OFF or disconnected.

3. Connect the power supply to DC+ and DC- terminals on the board.

4. Connect the DC+ wire of the board to IN terminal wire on the board.

5. Connect the Anode and Cathode terminals of external LED string between OUT terminal

and DC- wire of the board in the High side LED configuration.

6. Connect the DC- wire to the GND of the DC power supply.

7. Observe MAX 60V differential between IN and OUT terminals when applied Vcc > 60V.

8. In the high side circuit configuration, extreme high voltage may be present. Please use

caution and try not to touch any components on the board or input leads.

9. Turn on the main switch. LED string should light up and the LED current should be

regulated according to the current options of the device.
