Automatic test equipment for Transformers for fast and fool proof testing of COILS AND SMALL TRANSFORMERS like SMPS transformers, Telecom transformers (HYBRID, POT CORE, RM-CORE), Pulse transformers etc.
Automatic test equipment for Transformers for fast and fool proof testing of COILS AND SMALL TRANSFORMERS like SMPS transformers, Telecom transformers (HYBRID, POT CORE, RM-CORE), Pulse transformers etc. The systems scans at one stroke, all the windings of a transformer and tests as per definition of test procedure. The test procedure can be pre-programmed and stored under User friendly menu driven software . Any semi-skilled and unskilled person can be engaged for actual testing purpose. Can Select test frequency, pin number, parameters, test conditions, limits for each test. Test any pin to any other pin any defined parameter. Test parameters : Inductance, Capacitance, AC Resistance, DC Resistance, Impedance, Leakage Inductance, Transformation Ratio, Winding Polarity. SPECIFICATIONS :Measurement Frequencies: 50, 100, 500, 800 HZ; 1K, 2K, 5K, 10K HZ.Measurement Voltage: 0.1 V – 1.0 V RMS adjustable under program control.Four terminal or Kelvin type of testing: Provided to eliminate lead resistance.| Test Parameter | Range | Accuracy | |
