Overview
Phase rotation indicator in 3-phase units indicates a correctly sequenced power connection, prevent-
ing misleading line coupling, incorrect phase coupling especially precarious in synchronous mode and possible damage to the EUT.
The fully automated IEC and ANSI compliant coupling networks fulfill the new requirements for EUT currents over 16 A in the surge standard IEC / EN 61000-4-5:2005, as well special coupling modes and pulse amplitude control in the ANSI C62.45 standard, ring wave pulse given in IEC / EN 61000-4-12:2006.
The Teseq CDN 3063-S63 3 Phase, 63 Amp Automated Surge CDN Coupler for NSG 3040/3060 couples surge and burst pulses into 1-, 2- or 3-phase power mains of up to 480V with a current range up to 63 Amps. This range incorporate the new IEC draft standard’s provision for testing EUT’s with high power consumption. Reduced decoupling inductances in series with the EUT power connection are specified in order to minimize series voltage losses.
Teseq CDN 3063-S63 Features:
- Suitable for 3 Phase Combination wave & Ring wave Surge Test
- EUT Current: 3 x 63 Amp continuous
- EUT Voltage: 480V line to line, 280V line to neutral/ground
- EUT Frequency: DC – 65 Hz with no loss, 400 Hz max. with power loss
- Automatic CDN for use with Teseq NSG 3040 & Teseq NSG 3060
