Introduction

The DOS 400F fast damped oscillatory wave generator can complete the testing of fast damped oscillatory waves required by the IEC 61000-4-18 standard.

The DOS 400F has three selectable oscillatory frequency points of 3 MHz/10 MHz/30 MHz, and the highest test voltage can reach 4.2 kV. It is equipped with a high-power three-phase DC automatic coupling/decoupling network. Oscillatory waves are repeatable transient disturbances that occur on high or medium voltage power lines, control lines, and signal lines.

Features

> 5.7-inch color touch screen front panel operation

> The oscillatory frequency is 3 MHz / 10 MHz / 30 MHz, the test voltage up to 4.2 kV

> Built in high-power three-phase AC/DC automatic coupling/decoupling network, EUT with load capacity of AC 1,000 V 100 A, DC 1,500 V 100 A

> LAN Ethernet interface for remote control

> Automatically switch coupling routes

> Coupling path display (indicator light)
