Parameter Value
Supply voltage range (VS)
(1)
(2)
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.
32 V to 52 V
