D400 Series

D400 Series - Demodulators - Phase Sensitive AC to DC Converters with Isolated AC Input


  • High accuracy 
  • Low cost
  • Phase sensitive
  • Low null & Ripple
  • PC Card mounting
  • Hi input impedance
  • Easily interfaces with standard analog to digital converters
  • Output short circuit protected
  • Transformer isolated input
  • Low output impedance


The MOD 500 and D400 series of solid state modulators and demodulators are hi-accuracy, low cost, miniature, phase sensitive converters designed for military and industrial control applications. 

The demodulators convert an AC input signal to a linearly proportional DC output signal whose polarity is determined by the input AC reference phase.

The entire series feature low nulls, linearity of up to +/-.1% of full scale, and isolated inputs or outputs if required. Special scale factors can easily be provided upon request making these units the most flexible and smallest available in their price range.
