Product description
Product parameters
Reference standard: DL/T624-1997, JJG1112-2015.
Features:
● With 4-phase voltage 3-phase current output, it is easy to carry out various types of combined output for various types of protection tests. Each phase voltage can output 120V, current three can output 120A, and the fourth phase voltage Ux is a multi-function voltage term, which can be set to 4 kinds of 3U0 or synchronous voltage, or any voltage value output;
● Through the full set of Chinese operating software on the Windows platform, it can perform a variety of large-scale complex and more automated verification work, which can easily test and scan various protection settings, store test data in real time, display vector graphics, Draw fault waveforms, print reports online, etc.
● The ND-802 is a 7-way contact input and a 2-pair empty contact output. The input contact is an empty contact and is compatible with 0~250V potential contacts, which can be intelligently and automatically recognized. Input and output contacts can be expanded according to user needs;
● The device is equipped with a 110V and 220V dedicated adjustable DC power output.
