This in the Netherlands designed 2-channel DC LISN can be used up to 250V and 16A (30A pk).
Using the built-in DM, CM and single line measurement, the LISN05/16 facilitates problem analysis to find the origin of a line interference.
Selectable low-pass and high-pass filters eliminate measurement errors due to clipping of the measurement receiver. The filters are combined with a built-in attenuator/limiter that protects the spectrum analyzer from harmful input transients during power-up of the DUT.
This measuring instrument is designed by and for electrical engineers dealing with mains powered devices such as inverters, machines and power supplies.
The circuit used complies with the specifications of CISPR-25 with V-, — and T-network measurements. The simulated impedance is 5&mu,H || 50 in the frequency range from 9 kHz to 110 MHz. Filters are provided to limit the bandwidth.
The design is such that peaks up to 30 A are possible without loss of linearity.
