Com-Power Corporation LISN LIN-120A

The LIN-120A is a new LISN from Com-Power. A line impedance stabilization network (LISN) device is something engineers use to test radiofrequency (RF) emission and susceptibility. During an electronic equipment test, engineers place the LISN device between an alternating current or direct current power source and the equipment under test. Additional Features: Frequency Range: 150KHz-30 MHz RF Connector: 50 Ohms N-type (female) Current Rating: 20 Amperes AC, 14 Amperes DC Voltage Rating: 270 VAC (Line to Ground), 380 VDC Integral Transient Limiter/10 dB Attenuator with ON/OFF (bypass) Switch Dual-Conductor Network with Universal Power Receptacle to accept any EUT Plug Inductors: 50 microhenry (air-core) Mains & EUT Connections: IEC 60320, C-20 @Mains and Universal multi-configuration @ EUT Insertion Loss: <0.5 dB (150 kHz - 30 MHz) Isolation: > 40 dB (150 kHz - 30 MHz Operating Temperature: 40°F to 104°F (5°C to 40°C) Fully compliant with CISPR 16-1-2 / ANSI C63.4 “Air-core” inductors to prevent saturation Built-in Transient Limiter Individual Calibration Included Application: Power Line conducted emission tests Dimensions (each network): 14 x 13 x 6.5 inches / 35.5 x 33 x 16.5 cm Weight (each network): 10.5 lbs / 4.76 kg Three-Year Warranty The LIN-120A Line Impedance Stabilization Network (LISN) is in full compliance with both CISPR 16-1-2 and ANSI C63.4. It provides the necessary measurement platform for performing power line conducted emissions compliance testing as required by most worldwide standards for commercial products. The LIN-120A performs each of the following functions during the measurement: provides a defined, stable impedance across the measurement frequency range; isolates the EUT and measurement circuit from the power source, thereby minimizing its influence on the measurements; and, couples the disturbance voltages to the coaxial measurement port (either directly, or through a transient limiter w/10 dB attenuation, depending on switch position), for connection to the measuring instrument. This LISN uses air-core inductors to prevent saturation and permeability variation. Its mounting plate is left unpainted in order to facilitate connection to earth ground in its installation, which is essential due to high leakage current. Versatility The LIN-120A is a dual-conductor network capable of handling currents up to 20 Amps(AC) per line. The EUT power port is fitted with a universal, multi-configuration receptacle, which accommodates almost any EUT plug without the need for adapters. The power input port is fitted with a standard IEC C20 receptacle. The LIN-120A can be installed into any type of power system, including DC, single-phase, dual-phase and even three-phase systems. Transient Protection The LIN-120A is equipped with a built-in transient limiter to protect the RF input of your measuring instrument from potentially damaging voltage transients. The transient limiter also reduces the possibility of overload by incorporating two 5 dB attenuation/impedanc e matching pads, in addition to its low-pass and high-pass filters which further attenuate out-of-band emissions. When the Transient Limiter ON/OFF switch is on the “OFF” position, the transient limiter circuit, including the 10 dB of attenuation and band-pass filters are bypassed. Calibration All Com-Power LISNs are individually calibrated in compliance with the relevant requirements of CISPR 16-1-2 and ANSI C63.4. Impedance, Phase, Isolation, and Insertion Loss data is supplied with each unit, along with the certificate of calibration. Recognized ISO 17025 accredited calibration is also available upon request.
