Overview
The EMC Shop is an ISO 17025 accredited calibration company with the LISN-CISPR25-250 Line Impedance Stabilization Network Pair in stock available for sale or rental. Repair and refurbishment services available as well. Contact us now for application support.
LISN-CISPR25-250 is used in tests of CISPR 25 and ISO 7637-4 to isolate automotive components with power supply and also can be used in electric vehicle HV tests.
• The DUT voltage shall be within the rating range (DC1000V or 700V AC 50/60Hz), 300V(AC 400Hz) and its current shall be
not exceed 150A or 500A for short term operations. The temperature rises to 110 C under tests with DUT 250A for 2 hours,
and 110 °C under tests with DUT 400A for 10 minutes. In case of tests with bulk current, make sure to securely fasten the test
cable on input/output port.
• The temperature of the front panel could reach 60 C when the equipment is continuously working under maximum rated
power. Make sure the air in the test zone is flowable and don't cover any stuff on the equipment enclosure.
• When the equipment is used for the first time, it may generate the smell of coating and insulation material. The operator shall
take precautionary measures to avoid inhalation of the gas. The smell will be vanished after using the equipment for several
hours.
• There is high magnetic field and high-temperature risk during the current is injected. All the test work shall be operated by
qualified personnel and safety precaution measure shall be considered before tests.
• Before connecting with power supply, make sure the product is reliably grounded.
• The rear panel is equipped with a 0.1 μF capacitor. Prior to conducting the tests, make sure the voltage at the power input/
output port is discharged to a safety voltage range.
The electric energy of EUT input port will be converted into thermal energy in the resistor of 50/ 50W. Please note that there
is no any attenuation when RF energy is injected from EUT port to BNC output port. Higher RF disturbance voltage may
destroy the connected RF test equipment. Whether to connect external attenuator (such as 20 dB) depends on test equipment
performance and EUT disturbance voltage range.
