TBL501000-1 50uH Line Impedance Stabilisation Network LISN – CISPR 16

The TBL501000-1 is a high current single path 50µH // 50 Ω LISN for conducted emission measurements of DC or AC-powered electronic equipment. It is designed according to the CISPR 16-1-2 standard and characterized in the frequency range of 150 kHz to 30 MHz.

Combining two LISN with the Tekbox LISN Mate enables separate measurement of common mode and differential mode noise. EUTs with 3 phase supply require three or four pieces of TBL501000-1, depending on whether the product is supplied in delta or star configuration.

The LISN is equipped with fans to enable continuous operation up to 1000 A. The fans are available with either 100 V – 120 V or with 200V – 240 V supply voltage. A C14 connector with integrated switch sits on the rear panel. The LISN can be operated continuously with up to 500 A without fan.

An exposed stainless steel bottom profile enables convenient ground plane connection.
