EFT-CDN-3100/3200

EFT-CDN-3100/3200-690 is a high-voltage, high-current coupling/decoupling network for EFT pulse groups, designed for testing AC/DC power pulse groups. It enables automatic three-phase coupling and decoupling.

The maximum load capacity of the EUT (device under test) is:

• AC: 690 V, 100 A / 200 A
• DC: 1000 V, 100 A / 200 A

This is a three-phase, five-wire installation. Other voltage and current values can be customized according to customer requirements.

Features:

• Maximum EUT load (DC): 1000 V, 100 A / 200 A
• Maximum EUT load (AC): 690 V, 100 A / 200 A, three-phase, 5-wire
• Overload protection
• High-voltage aviation connector, safe and reliable
• Built-in parameters compliant with international standards, easy to use
• Freely adjustable pulse injection phase: asynchronous or within the range of 0–360°
• Pulse frequency up to 1200 kHz, can be further increased
• Built-in RJ45 interface, optional Measurement and remote control software

Compliance with standards:

• IEC/EN 61850-3
• ANSI/IEEE C62.41
• GB/T 17626.4 / IEC 61000-4-4
• IEC/EN 61000-6-1
• EC/EN 60601-1-2
