Product Overview

RENT emtest V4780S2 V4780 S2 Auto Transformer

The emtest V4780S2 ( V4780 S2) tapped auto transformer can be used to simulate power supply failures as voltage interruptions. The basic standard EN/IEC 61000-4-11 Ed.2 specifies this phenomena. 

Voltage interruptions ( DIPS ):

Voltage interruptions will cause a reduction of the power supply voltage for a certain period of time. Four different test levels are required:

• Reduction by 100% to 0% of the nominal voltage
• Reduction by 60% to 40% of the nominal voltage
• Reduction by 30% to 70% of the nominal voltage
• Reduction by 20% to 80% of the nominal voltage

The emtest V4780S2 is used in conjuction with the emtest UCS500N5 or the emtest NX5
