VCS 500N7T

Surge pulses occur due to direct or indirect lightning strokes to an external (outdoor) circuit. This leads to currents or electromagnetic fields causing high voltage or current transients. Another source for surge pulses are switching transients originating from switching disturbances and systems faults.
Due to the characteristic of the phenomenon nearly every electrical and electronical device may suffer from such lightning events which justifies the necessity of surge tests being widely performed. Surge voltage can reach several thousands of volts and surge current is seen to reach several thousands of amps.

The VCS 500N7T unifies the test capabilities for Combination wave surge and telecom surge testing in one unit up to 7kV. Moreover, it offers built-in coupling/decoupling networks for single phase AC power port and telecom port testing.
For combination wave surge tests on high-current mains supply lines its capability can be extended by an external CDN to achieve nominal currents of 100A and more per phase.
By selecting the desired coupling the source impedance and the coupling capacitor is set automatically what ever CDN is connected.
Fail inputs are offered as standard for DUT monitoring purposes. Peak values of voltage and current are shown in the display and these values are transferred to the software for reporting.
To comply with safety regulations the VCS 500N7T is equipped with a contact to control warning lamps and with a safety interlock.
Pre-programmed Standard Test routines allow highest user convenience. Still the VCS 500N7T offers the Quick Start test routine where parameters can be changed on-line during the test to evaluate the susceptibility level of an individual DUT.

Front panel menu and function keys enable the user to program his test routines quickly and accurately. The cursor allows fast control of all test parameters of the programmed routine, thus test procedures are simplified and confidence is generated that every step is carried out correctly.

Outstanding user convenience, clearly structured windows and operation features and the EM TEST standards library along with the flexibility to generate user specific test sequences very easily are the main features of iec.control software. The software is automatically configured according to the connected EM TEST generators. Extensive reporting capabilities help the user to create test reports that meet international requirements.
iec.control is supported by Windows 2000, Windows XP, Windows Vista and Windows 7. Remote control is achieved either via USB or GPIB. iec.control supports a wide range of GPIB cards of National Instruments.
