Pico Electronics: AC-DC Converters LPHA-1 PHA-1

AC-DC Converters

LPHA-1 (250 Watts) PHA-1 (500 Watts)

Universal AC input regulated to 365 VDC Output
or use with PICO's Hi-Power Models
for 3.3 to 100 VDC Outputs Single or Dual
Meets EN/IEC 6100-3-2 Requirements

New Unity Power Factor Front End

PICO's LPHA1/PHA1 is the perfect match for universal AC inputs to your worldwide DC applications. Used with PICO's LPD, PD and HPD Series of DC-DC Converters you can obtain a variety of DC outputs from 3.3 VDC to 350 VDC in single and dual outputs. Many Laser and Motor Applications are able to use the LPHA1/PHA1 directly because of its unique 365 Volt regulated output. Regardless of use PICO always optimizes Size, Reliability and Cost.
