Diode & Rectifier Testers

Font Size
  • CDT Series - Diode and Rectifier Testers: CDT-150The CDT-150 is a microprocessor based diode tester designed to provide remanufacturers with quick, accurate and easy to use device to test all main parameters of regular and avalanche rectifiers.
  • The tester automatically scans all diodes in the rectifier and measures each one of them separately.
  • The full test takes 5-6 seconds to complete.
  • The measured values are compared with preset limits and PASS or Fail is indicated, according to the results.
  • The readings can be taken even with the stator attached to the rectifier.
  • An audible beeb is heard when the diode or rectifier has passed the test.
  • The tester can detect the direction of the diode and automatically reverse the test probes to provide proper measurement.
  • The limits are fully programmable by the operator.
  • The tester can store specifications for popular rectifiers.
  • Optional enclosure and fixtures available for many popular rectifiers (enclosure and fixture in photo are optional)
