Power Factor Corrected DC Power Supply - PF Series
The PF Series Switching DC Power Supply, is Power Factor corrected, designed to deliver variable DC power upto 30KW in a constant voltage mode. It covers a current range from 20A to 1200A, in Four Voltage Settings (30KW max). Higher rated power supplies can also be supplied against specific requirements.
This range comes, housed in 19" rack mounting construction, with modules in multiples of 2.5KW each which can be connected in n+1 configuration with equal current sharing parallel operation of upto 12 modules. The DC Output power can be upgraded by adding modules on to the rack at a later stage. This provides maximum flexibility to the user to plan for future & order modules at a later stage.
The PF series power supply is used to simultaneously supply the DC load and recharge the battery. This type of DC system is widely used in Power Generation and Distribution, Instrumentation, Onshore and Offshore Petro-chemical applications etc.
