  • Direct Drive via chuck gripping directly on alternator shaft, tests alternators with or save time by testing without installing a test pulley
  • Measures over 100 different alternator parameters
  • User configurable Pass and Fail printed reports and labels through a PC and the ALT Report program for virtually unlimited flexibility, or directly to a printer interface from the test-unit, both can include performance curve, oscilloscope pattern, and test results
  • Learning Mode records sample test results for easy setup of test specifications in just minutes
  • Checks all types of alternator and voltage regulator terminals and functions such as computer control, soft start delay, feedback, under/over voltage indication, PCM control, load response control, tachometer frequency. Simulates all signals to the alternator including on-board computer functions
  • Measures turn on speed, ripple current, input power, voltage regulator instability, stator voltage, reverse diode leakage, can test rectifier voltage drop, regulator saturation voltage, and torque and efficiency (optional)
  • 15 or 20 hp computer controlled variable speed motor with high reliability Mitsubishi motor drive
  • User configurable test procedures with test time from 10 to 60 seconds
  • Measures full output performance curve in 15 seconds
  • Large LCD screen for viewing test results, performance curves, and user friendly controls
  • Computer controlled 500 Amp load bank
  • Endurance test mode for component validation
  • Test result statistics can be recorded for SPC or analysis
  • Automatic connections to the device under test
  • Built-in automatic, manual, calibration, diagnostic and detailed report test modes
  • Available in many working voltages (220 to 480V at 50/60 Hz)
  • Built in battery simulator 12-32V for consistent test conditions
  • Test specification database editor for Windows
