SETUP PROCEDURE
Powering the CL88030 230 V
AC
Offline LED Driver evaluation board is easy. The only
connections to be made are from the LED Driver board to the LED Load assembled on
a pin-fin heat sink, using the provided 10-wire flat cable, and from the LED Driver Board
to the AC line via the power cord.
Follow these steps:
1. Read the getting started recommendations and precautions.
2. Set the jumper J4 on the LED Load board between positions 2 and 3 to activate
the NTC for the OTP (this is specific when using the LED Load with ADM00860).
3. Connect the CL88030 LED Driver evaluation board and the CL88030 LED Load
board by means of the provided 10-wire flat cable, between J2 and J3 connec-
tors. It is recommended to exercise caution, as the connectors on the flat cable
are protected from incorrect connection.
4. Connect the power cord on J1 on the LED Driver board. The input connector J1
is placed on the left side of the LED Driver board, which is marked with the
inscription: AC.
5. Use a colored plexiglass above the LED Load board for eyes protection against
extreme light.
6. Plug the power cord into a 230 V
AC
outlet and apply 230 V
AC
±15%, 50 Hz. While
it is possible for the values to be below this range, it is recommended not to
exceed 277 V
AC
. In this case, the transient protection feature is automatically
activated. Line frequency is not critical (50 Hz or 60 Hz).
A variable AC power supply is needed for testing and evaluation in the laboratory. The
power supply requires an output capability of at least 20W and a voltage range from
0 V
AC
to 300 V
AC
. This can also be obtained from an auto-transformer supplied from
the mains or an electronic AC/AC power supply (for example, the Chroma ATE Inc.
61500 series).

Note:
Auto-transformers do not provide isolation from the utility mains.
