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.
