Step 3: Power-down the Board
g
Switch off the high-voltage AC power input
Step 2: Power-up the Board
g
Connect an electronic/resistive load to the corresponding marking (CN2).
The requirements for the resistive load are:
• At 115V
AC
input: 150W to ≤1250W
• At 230V
AC
input: 350W to ≤3300W
g
With the high-voltage power off, connect the high-voltage AC power input to the
corresponding marking (CN1) on the PCB; N and L (PE: potential ground)
g
Turn on the AC power input (85V
AC
to 265V
AC
, 50Hz to 60Hz); minimum power
load for turn-on sequence is 150W
g
Monitor CN2 output voltage with V
DC
meter to verify that 385V ±5V is generated
g
Load can be increased when AC supply is on and board is functional
