The NV-Power family of configurable AC-DC power supplies enables increased power output of up to 1,450 W peak rating for 10 seconds. The modules satisfy the increasing demand for low-profile configurable power solutions from 350 to 1,000+ W for broadcast, instrumentation, medical equipment, ATE, automation, routers, servers, and security networks.
The modules integrate a magnetic transformer that allows for small size and increased efficiency. The digital control allows customizations based on the application's requirements (such as modified current limit or start-up characteristics). Additionally, the input-to-output isolation meets the 4 kV AC-reinforced requirements for medical use.
NV-Power employs an 8-bit microcontroller to handle housekeeping routines, replacing the array of comparators, op amps, and other discrete components used in less integrated designs. This brings a 50% parts count reduction which in turn allows 40% more board space for power components. With the incredibly high peak power rating designers can realize power densities of up to 19 W/in3.
All units operate with an input range of 90 to 264 V AC. The NV-350 series provides up to 350W of output power with <180 V AC mains, and up to 660 W continuous (740 W peak for 10 seconds) with >180 V AC mains. Up to 6 user-selectable outputs can be provided in a 2 x 4 x 11-in package.
While the NV-700 series provides up to 700 W of output power with <150 V AC mains, and up to 1,150 W continuous (1,450W peak for 10 seconds) with >150 V AC mains. Up to 8 user-selectable outputs can be provided in a 2 x 5 x 11-in package.
Multi Resonant Topology (MRT) and other EMC-improving design features have resulted in meeting Curve B EMC performance with earth leakage current less than 300 µA at 264 V AC, 63 Hz (meeting the requirement for IEC/EN/UL60601-1).
Available with an extensive range of output modules and options, it's possible to achieve a wide range of output voltage and current combinations. All outputs are fully isolated, no minimum load is required and each module features output-good and inhibit control signals. Of particular note, the new digitally controlled single-output 'C' module is 3 slots wide and available with 12, 15, and 24 V outputs offering as much as 400 W continuous and up to 600 W peak output power for up to 10 seconds.
