- KYORITSU TECHNOLOGY Line Impedance Stabilization Network TNW-342F
Line Impedance Stabilization Network
These networks are Artificial Mains Networks (AMNs / LISNs) used to measure interference voltages leaking from a disturbance source to the power supply lines, within the frequency range of 150 kHz to 30 MHz in compliance with CISPR (International Special Committee on Radio Interference) standards.
In addition, these networks can measure from single-phase to three-phase three-wire systems depending on the number of phases of the EUT (Equipment Under Test) lines. Furthermore, the measurement lines can be switched using either the switches on the main unit or a remote switch.
By registering the correction factors of this instrument into our interference immunity/intensity measuring apparatus (TNM-2401 and TNM-2402), they can be automatically added via key operations, allowing for direct-reading measurement of disturbance voltage.
