Introduction

SEPN 48200T HV High-Power Coupling/Decoupling Network complies with IEC/EN 61000-4-4/-5 that enables fully automatic three-phase coupling and decoupling. It supports both AC and DC power supplies and is compatible with CCS, CWS, and EFT series test instruments.

The Max. EUT load capacity up to 480 V AC / 200 A or 1,000 V DC / 200 A. Custom voltage and current ratings are available to meet specific test requirements.

Features

> EUT AC load capacity AC 480 V 200 A three-phase five-wire

> EUT DC load capacity DC 1,000 V 200 A

> Current range: 0 ~ 200 A; four automatically selectable ranges: 0 ~ 32 A, 32 ~ 63 A, 63 ~ 125 A, and 125 ~ 200 A

> Overcurrent protection

> Scheduled setting of test parameters, including test voltage, polarity, and phase synchronization angle, for fully automated network switching

> Phase angle superposition between any lines

> Coupling path indication (indicator lights)

> Selectable coupling resistor: IEC standard or user-defined

> Safe and convenient plug-in insulated connectors

> Emergency stop automatically disconnects EUT power and high-voltage pulse circuits
