LSS-15AX-A1A
LSS-15AX-C3A



GENERAL


Surges represent transients that might be induced in cables by lightning.By their nature, fairly high energy charges may easily damage or upset unprotected electronics circuits and components.Surges are not a new problem.Many companies have been testing their products at various stages of the products life: design tests, qualification tests, production tests and diagnostic tests.

The advance of surge suppression devices and technique does not lessen the importance of surge testing, but rather increases it, as the requirement to reduce power consumption and to increase the operational speed of semiconductors has become more demanding. In addition, the issue of surge testing is attracting renewed interest since this form of immunity is now a must for almost all electronic products for access to the global market.


FEATURES
Fully compliant with the requirements called for in the 2ndedition of IEC 61000-4-5 standard, the LSS-15AX series simulators provide a testing facility for up to 15kV test voltage without sacrificing safety and ease of use. The LSS-15AX simulators generate the two combination pulses 1.2/50 µs (8/20 µS) and 10/700 µS (5/320 µS).

  • Fully programmable and easy to use simulator that meets andfar exceeds theIEC 61000-4-5 (2ndedition)requirements
  • 15kV testing
  • Advanced safety
  • Flexible test sequencing with Program Mode



FUNCTIONS


  • Easy operation
Very intuitive settings can be done by the assistance of the well configured user-interface consisting of a 5-inch LCD, ten-key, functions keys and others. Coupling modes are graphically shown, allowing the operator to select the desired mode and allows easy reference of settings when the test is in progress.

  • Emergency stop button
This button, easily accessible and placed on the front panel, enables the operator to stop the generation of the pulses anytime he/she desires. In addition to the high voltage power, the operator can turn off the EUT.

  • Safety interlock
A safely interlock is provided through the special design high voltage connector. The high voltage circuitry never be activated when the connector is not correctly positioned or not firmly locked.

  • Peak level monitor
The value of the actual peak amplitude is measured and shown for both voltage and current.







  • Automatic stop by detecting breakdown
The simulator automatically stops generating the pulses if the peak current measured exceeds the threshold limit which can be freely set as the breakdown criteria.
