Introduction

PFS 3875TDC AC/DC Drop-out Switch is designed in compliance with IEC 61000-4-11, IEC 61000-4-29 and IEC 61000-4-34.

It simulates voltage dips and short interruptions caused by power grid faults, substation equipment failures or sudden large load changes.

This device is fitted with controllable semiconductor switches, capable of withstanding transient inrush current and equipped with electronic short-circuit protection.

Features

> 5.7-inch color touch screen front panel operation

> Test sequence function

> Adopts imported high-power IGBT semiconductor switches

> Support simultaneous voltage interruption and dip tests for three phases

> Current measurement and acquisition

> Ethernet RJ45 interfaces for PC remote control and printing test reports
