Nortelco Electronics har fått ny webside
Nortelco Electronics AS ble Adeptor AS fra 1. januar 2022, men dine kontaktpersoner er de samme! Endringen gjelder områdene Elektronikk og Automasjon, og vi har fått ny webside.
The VSS 500N6 is designed as per IEC 60255-5 meeting the requirement to maintain a constant pulse energy at different test levels as specified by the standard. Such tests are specified for transient overvoltage tests on protection relays. The test generator itself follows the specifications as per IEC 61180-1 and covers the predefined voltage levels corresponding to the most used test voltages used for relay testing.
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 VSS 500N6 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 VSS 500N6 offers the Quick Start test routine where parameters can be changed on-line during the test.
