For all variations, call factory.
For Parallel Operation: Add suffix "P" (i.e.
PA5SP). Consult factory to optimize for
your application.
This high density unit is assembled in the USA with PICO quality
and component selection, allowing it to meet the most stringent
commercial requirements.
The PICO PA Series of high power DC-DC Converters, allow a wide
input voltage of 18-36 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 operations as standard features should reduce
your design and component costs, while the fixed frequency
operation helps parallel connections for higher power requirements.
