54 Standard Models
The PICO FD and MD Series of high power DCDC Converters, allow a
wide input voltage of 200380 VDC, while maintaining a regulated output.
They are fully safeguarded for over voltage, over temperature and continuous
short circuit protection.
The availability of Dual Isolated outputs, small size, and the capability of
parallel operation as standard features should reduce your design and
component costs, while the fixed frequency operation helps parallel
connections for higher power requirements.
This high density unit is assembled in the USA with PICO quality and
component selection, allowing it to meet the most stringent commercial
requirements.
For all variations, call factory.
For Parallel Operation: Add suffix "P", (i.e. FD/MD5SP)
Consult factory to optimize for your application.
