FeaturesALT-50DN

  • Fully automated precise testing for especially for large frame high output applications for transit, bus and coach applications
  • Available with preheated oil circulating system for cooling and lubrication
  • Available pressurized air system to check seal integrity
  • Direct Drive via rotor shaft, test alternators with pulley or save time by testing without installing a test pulley or via belt drive system for small frame alternators
  • 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 tester, 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 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, pulley size, input power, voltage regulator instability, stator voltage, reverse diode leakage, can test rectifier voltage drop, regulator saturation voltage, and torque and efficiency (optional)
  • Up to 50HP computer controlled variable speed motor with high reliability Hitachi motor drive
  • User configurable test procedures with test time from 10 seconds to 15 minutes or longer
  • Measures full output performance curve in 15 seconds
