TESEQ DC LISN M2-25-V2 Dual-Line LISN for GCPC

Description

Teseq introduces a new Line Impedance Stabilization Network (LISN) for conducted emissions testing of Grid Connected Power Conditioners (GCPC). The DC-LISN-M2-25-V2 is designed for measuring disturbances on DC power ports in the frequency range from 150 kHz to 30 MHz. Research results have shown that typical artificial mains V-network as described in CISPR 16-1-2 cannot be used for the assessment of unsymmetrical disturbances of a photovoltaic inverter’s DC port. CDNs based on IEC/EN 61000-4-6 are typical not specified for high common-mode currents and differential-mode disturbances. Additionally, they are undefined below 150 kHz.

The DC-LISN-M2-25-V2 provides enhanced LISN performance with a common-mode impedance of 150 Ω and a differential-mode impedance of 100 Ω. Depending on the switch position, the LISN works as V, Y or Delta shape LISN. Further, the DC-LISN offers defined termination impedance in the frequency range 1 kHz to 150 kHz.

The DC-LISN-M2-25-V2 conforms to the latest requirements of the international standard working group MT GCPC: GRID CONNECTED POWER CONDITIONERS.

Features

  • Frequency range 150 kHz to 30 MHz
  • 150 Ω DC-LISN for photovoltaic inverters
  • Switch for selecting the LISN type: V, Y, Delta
  • 4 mm banana sockets
  • Metal casing, ruggedly designed
