Tekbox TBL501000-1 LISN
Details
The Tekbox TBL501000-1 is a high-current, 50µH, 1000A LISN for conducted emission measurements on high-powered AC/DC electronic equipment. Designed in accordance with CISPR 16-1-2, it is designed to present a defined supply-line impedance while allowing noise at the EUT terminals to be taken from the RF output and measured with a spectrum analyser or EMI receiver. The LISN has a bandwidth of 100kHz to 30MHz, and an operating voltage range of up to 1000V DC or 500V AC. It can also operate continuously with a current capability up to 1000A with fan cooling, for which the fans require an external power supply. Without this fan, the LISN can still operate at up to 500A continuously. Two of these LISNs can be used together with the Tekbox LISN Mate. This setup enables both common-mode and differential-mode noise measurements.
