Electronic Power Transfer Switch (EPTS) Option for EMC Compliance Testing

Available only in Asia & European Markets. Coming to North America in 2024
The Pacific Power Source EMC Compliance Test Systems may be equipped with an electronic power transfer switch (EPTS) module that supports the requisite voltage rise and fall slew rates for IEC AC Voltage dips and Interruptions and Voltage Unbalance immunity testing per IEC61000-4-11, IEC61000-4-27 and IEC61000-4-34.
This model series consists of several system configurations to accommodate both single and three phase compliance testing with current levels starting at 16Arms up to 100Arms. All EPTS models are provided with Windows 10 GUI software with IEC61000-4-11 (AC < 16Arms/phase), IEC61000-4-27 (AC 3 Phase < 16Arms/phase) and IEC61000-4-34 (AC < 75Arms/phase) Immunity test software.

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:
Immunity
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!

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.
