  • 23 Standard Models
    Hi Density 75 Watts
    Fixed Frequency
  • For all variations, call factory.

For Parallel Operation: Add suffix "P" (i.e. LPD5SP). Consult factory to optimize for your application.

 The PICO LPD Series of high power DC-DC Converters, allow a wide input voltage of 200-380 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.

This high density unit is assembled in the USA with PICO quality and component selection, allowing it to meet the most stringent commercial requirements.
