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
