MOD Series

MOD Series - Modulators - Phase Sensitive DC to AC Converters with Isolated AC Outputs


  • High accuracy
  • Insensitive to reference voltage changes (+/-10%)
  • Gain &Zero adjust
  • Phase sensitive
  • Low null & Distortion
  • Low output impedance
  • Low cost
  • Highly reliable
  • PC Card mounting
  • Output short circuit protected


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 modulators convert DC input signals to linearly proprtional AC output signals. The polarity of the input signal determines the phasing of the output signal. 

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.
