Product Description

The DTSk2 measures, calculates and displays the primary electric parameters in balanced or unbalanced three-phase industrial networks. True rms values are measured using three alternating voltage inputs, two voltage references (neutral and ground), and four current inputs to measure secondaries 1A or 5A, coming from the outside current transformers. It should be considered that when secondary 1A is selected, the calculation is made by the software.

The DTSk2 network and power supply quality analyzer is a programmable measuring instrument. It offers a wide variety of uses, which can be selected from the instrument’s configuration menus. Prior to using the analyzer, read the following sections carefully: power supply, connection and configuration. Then, choose the best operating method for obtaining the desired data. The DTSk2 permits viewing the electric parameters on a backlit 1/4 vga graphical display. real time, maximum or minimum electric parameters can be viewed by pressing the corresponding key. The DTSk2 internal processor shows more than 500 electric parameters via the display screen and communication; these parameters may be fed from a single or three phase system.
