Full EMC Compliance Testing of Specific Immunity IEC Standards

The EPTS Option allows EMC Test labs to perform full compliance testing of products to the following IEC standards:
IEC 61000-4-11 AC Voltage Dips, Interruptions and Variations to 16A/phase
IEC 61000-4-27 Three Phase
Voltage Unbalance to 16A/phase
IEC 61000-4-34 AC Voltage Dips, Interruptions and Variations to 75A/phase
See the ECTS2 systems product pages for a comprehensive and cost effective solution to all of your EMC compliance testing needs!

Key Features

EPTS Option Key Features


IEC 61000-3-2 & IEC 61000-3-12 Harmonics and Inter Harmonics Emissions Test

When combined with ECTS2 Harmonics and Flicker Test System, AFX AC & DC power source or LMX AC Power Source.

AC Voltage Dips, Interruptions, Variations and Unbalance

The EPTS is designed to work with two AC sources, one of which must be programmable. In locations where the grid voltage is stable and has the correct voltage and frequency, the grid can be used for the nominal test voltage. The dips and interruptions levels are always provided by the programmable AC source.

Three Phase AC Voltage Unbalance

The EPTS Windows also supports Voltage Unbalance immunity testing for 3 phase loads per IEC 61000-4-27.
