ISA STS 4000 Offers

The STS 4000 is equipped with AC and DC high current outputs, AC and DC high and low voltage outputs, and current and voltage meters and allows to perform accurate tests on CTs, VTs, PTs and ground grid.

In the local control mode, the selected output is adjustable and metered on the large, graphic LCD display. With the control knob and the LCD display, it is possible to enter the MENU mode, that allows to set many functions, that make STS 5000 a very powerful testing device, with manual and automatic testing capabilities, and with the possibility to transfer test results to a PC via ETHERNET or Pen Drive. The TDMS software, which comes with the test set, allows to download, display and analyze test results obtained in local mode. Remote maintenance and diagnostic of the instrument is available via Ethernet.

Features

  • Variable output frequency: 15 - 500 Hz
  • 2000V AC high-potential test
  • Local control by large graphic display
  • USB and Ethernet interfaces for PC connection
  • Compact and lightweight
