ITC57600 Transient Voltage Suppressor Surge Tester
Overview
The ITC57600 Tester is a programmable current waveform generator that is used to surge, test and measure voltage breakdown on many different device types. These include Transient Voltage Suppressor (TVS) diodes, as well as MOSFET and BIPOLAR Transistors, Zeners, Rectifiers, MOVs, Polyswitches and PTC devices.
The ITC57600 performs compliance testing of transient voltage suppressor diodes to insure conformance to Bellcore, REA and other regulatory specifications.

TVS devices are used to protect sensitive electronic equipment from power line voltage spikes caused by lightening, power line fluctuations, inductive load spikes, and other power line anomalies. For this reason, it is important to quantify the surge operation of these devices in either the forward or reverse direction and to precisely measure and specify the breakdown current and voltage.

Operation
Engineering Mode - Operation and control of the ITC57600 is handled by RS-485-based PTNet server software and the EM57600 Engineering Mode Application Software. Test parameters can be created, verified and saved, and test results can be verified using the EM57600. The EM57600 also generates test reports.

Production Mode - Operation and control of the ITC57600 is handled by RS-485-based PTNet server software and the PTNet Production Mode software. The test parameters created by the EM57600 program are used for the tester operating in Production Mode. The Production Mode software controls all of the testers on PTNet and manages test results from each tester in a production environment.

Features
  • Easily create any current waveform which can be described by an equation or data file
  • An intuitive user interface via graphic LCD Touchscreen
  • ITC PTNet provides networking capability
  • Self-calibration ensures all test measurements are in tolerance
  • Front panel BNC jacks allow easy monitoring of the test cycle
Waveforms
Waveforms are generated by a precision wave-shaping computer algorithm for the highest possible degree of accuracy. The waveform can be user defined to meet a specific device test requirement, or it can be loaded from the standard library of waveforms that include the following: The 10 x 1000 �s and 8 x 20 �s double exponential waveforms are based on the Bellcore and Rural Electrification Administration Document PE-60 definitions.
  • 10 x 1000�s, Double Exponential
    Ipk = 10 mA up to 750 Amps*
    Vpk = 400 Volts
  • 8 x 20�s, Double Exponential
    Ipk = 10 mA up to 750 Amps*
    Vpk = 400 Volts
  • Pulse
    Ipk = 10 mA up to 750 Amps*
    Vpk = 400 Volts
    Tr = Tf = 10�s
    Pulse Width up to 100mSec
  • One-half Sine Wave
    Ipk = 10 mA up to 750 Amps*
    Vpk = 400 Volts
  • *Note: Maximum current rating limited by:
    Ipeak x VPeak, at least 25KW-peak power up to a
    maximum of 128KW, or by the Current Regulator's SOA
    as defined by the current waveform.
Power Up Tests
  • All power supply voltages are verified
  • DUT contact voltages are in the safe zone
  • Power supply temperature is safe
  • Current Regulator temperature is safe
  • ITC57600 top cover is in place
  • Power supply high voltage is off
  • Communication via PTNet is verified
Self-test Modes
  • Self-test when power is applied
  • Self-test before first DUT is tested after parameters are downloaded to tester
  • Self-test while test data is being uploaded from the tester to the server PC
