Supply voltage range (VS)

1.

Minimum VS voltage restriction is due to biasing current of the Zener diode used to generate V

cc

. This limit 

can be decreased by changing R29 value or by opening JP3 and providing an externally generated V

cc

 

through connector J1.

2.

Maximum VS voltage limit can be increased up to 580 V by replacing the power switches and bulk 
capacitor C15 with components with adequate voltage ratings. Resistor R29 should be removed and an 
externally generated V

cc

 should be provided through connector J1.
