Introduction

The EFTN 150125T HV High Power EFT/Burst Coupling/Decoupling Network is designed in compliance with IEC 61000-4-4. It enables fully automated three-phase coupling/decoupling and supports both AC and DC power supply testing.

Compatible with CCS and EFT series simulators, it supports EUTs with a maximum load capacity of AC 1,500 V, 125 A or DC 3,000 V, 125 A (three-phase five-wire). Custom configurations are available for other EUT voltage and current ratings.

Features

> Max. coupling voltage 7.2 kV (5/50 ns)

> Supports DC EUT loads up to 3,000 V, 125 A (Support customization)

> Supports AC EUT loads up to 1,500 V, 125 A, three-phase five-wire (Support customization)

> Test schedule of parameters, including test voltage, polarity, and phase synchronization angle, enabling fully automated network switching;

> Supports arbitrary phase angle superimposition between any line combinations

> Coupling path indication (LED indicators)

> Selectable coupling resistance according to IEC standards or user-defined configurations

> Plug-in insulated connectors for enhanced safety and convenience;

> Emergency stop button automatically disconnects EUT power supply and high-voltage coupling paths.
