PFE Series, simple function
This range of ‘front end’ converters can be used to
create quick to market, low profile single output PSU
directly power user loads, or combined with any suitable
DC-DC converter to facilitate a multi output ‘custom’ PSU,
complete with PCF, harmonic compliance, and meeting
latest IEC immunity standards.
• Wide AC input voltage range
• Power factor / harmonic correction
• 3kVAC input / output isolation
• IEC61000-4 immunity compliance
• Wide output voltage adjustment / trim range
• Remote sense
• Current share, droop mode (PFE700S)
• Constant switching frequency
• Power on signal
PFE Series, full function
These front end converters benefitting from the additional
control elements below, facilitate an even greater level of
functionality, allowing the user to simply realise complex
high power ‘custom’ PSUs using standard building blocks.
• All above bullet features and additionally
• Isolated remote on / off
• Active current share
• Auxiliary supply
