BOARD TESTING
To start testing the evaluation board, follow these steps:
1. Connect the input AC source and the output LED Load, as shown in
2. Use an eye protection filter to check that all the four taps light up on the LED Load
Board.
3. Power the board at 230 V
AC
, 50 Hz-60 Hz.
4. Verify each tap current through the LEDs. It should be within a range of 65 mA
and 134 mA. It can be measured by separating each wire from the
inter-connection 10-wire flat cable between the CL88030 LED Driver board and
the CL88030 LED Load board.
5. If a variable AC source is available, set the input voltage to any value between
180 V
AC
and 245 V
AC
. The LED Load delivers nearly constant lumen power. The
application delivers between 10W and 14W electric output power.
6. Power-down the AC source.
