Teseq, a developer and provider of instrumentation and systems for EMC emission and immunity testing, has released the DC-LISN-M2-100, a high current impedance stabilization network (LISN) for measuring conducted emissions disturbances of DC power ports of photovoltaic inverters.
According to the company, “[the] unit offers a maximum operating voltage of 1,500 V and measures disturbances over a frequency range of 150 kHz to 30 MHz. The DC-LISN-M2-100 provides improved performance [and] testing with impedance levels of 150 Ohms in common-mode and 100 Ohms in differential-mode.”
In addition, “the DC-LISN-M2-100, which conforms to the latest requirements of the international standard working group MT GCPC (grid connected power conditioners), can run at a maximum operating current of 150 A for 30 minutes, or continuously at 100 A.”
