Kilowatt DC Regulated Supplies - VO Series
 
The VO Series are variable voltage DC power supplies, wherein the DC Voltage can be set from 10% to 100% of the rated capacity, over the specified line variation, and the load variation from no load to full load. This series has been specially designed to test DC input variation performance of the connected equipment. In addition it offers user selectable option of either Re-entrant/Shut-off type overload and short circuit protection.
Re-entrant Type : During overload condition the output current is limited and when this condition is removed the voltage will build to set voltage automatically in soft-start mode. This is useful for applications where loads draw very high inrush current for a short period.
Shut-off Type : During overload condition or short circuit the output will shut-off. The unit can be manually reset by ON/OFF switch.
