The Line Impedance Stabilization
Network HM6050-2 is designed for compliance level measurements of conducted EMC
emissions. The unit complies with VDE 0876
and CISPR Publ. 16 (band A and B) regulations and can be operated manually or PC
controlled via the built in RS232 interface. It is designed and built using air
core inductors to avoid saturation at peak current loads
The unit comprises an artificial hand simulation per ANSI C 6.3.4, as well as a
PE simulation network (50µH II 50Ω)
which can be bypassed. For the protection of sensitive inputs, the output signal
can be limited by a switchable transient limiter.
The HM6050-2 LISN is used with a spectrum analyzer or
measurement receiver. The continuous rating of 16A makes the unit suitable for
many types of single phase equipment. The maximum permissible frequency is 63Hz.
The HM6050-2 can be supplied with a range of power outlets such as IEC16A,
UK13A, and European standard sockets.
The LISN is, in principle, a high pass filter when viewed
from the EUT (equipment under test) to the measurement terminal. The high pass
filter output signal is switched from either conductor to the measurement
terminal. Viewed from the power line side the LISN is a low pass filter that
isolates disturbance from the power line by up to 40dB.
Compact size and light weight make the HM6050-2 an easy to
use tool for commercial, ISPR based conducted emission testing on your EMC test
bench. It can be used for in house compliance level measurements, reducing the
need for test house time.
