LED, PD, PT and Power Semiconductor Testers

tester

Beside the test handlers we also provide a wide range of Testers for Diodes, High Power Transistors, Bridge Rectifiers and Optoelectrical Applications.

All testers have the following features:

  • Large 40 characters x 16 lines or 240 dots x 128 dots LC display and 25-key keyboard
  • 87C196 16-bit microprocessor controller with high speed 14-bit A/D converter
  • High voltage is generated by a small high frequency transformer
  • Versatile interface settings for easy connection with machine handlers
  • 4 to 10 sets of programmed parameters can be stored
  • RS-232 serial port interface
  • Real contact resistance value test
  • Slot mounted PC boards with on-board calibration
  • Standard 19" instrument rack case

The testers are available for either 220V/50Hz or 110V/60Hz AC power source. All parameters can be set via the keyboard or downloaded from an IBM compatible PC via RS 232 interface. The PC download software is optionally available. All testers can be linked with the handler via a direct interface or by PLC.


The following test systems are available:
