System tests automotive emissions
-- Test & Measurement World, 9/1/2008
The AES 5500 EMC transient emissions test system from Teseq lets you test automotive systems for conducted electrical transients. Designed for tests compliant with ISO 7637-2, the system consists of a mechanical switch, a line-stabilization network, an electronic switch, and a controller. To perform a test, you connect a power source such as a battery to the mechanical switch.
When you apply power to the equipment under test (EUT), the system lets you capture EUT disturbances. The EUT connects to the electronic switch; when the electronic switch closes, the disturbance passes through to the EUT, and you can capture the EUT’s response with an oscilloscope. The system can handle battery current up to 100 A with a 1000-A inrush current for 10 ms or with a 300-A inrush current for 1 s. You can also connect multiple mechanical switches and close them simultaneously.
Base price: $12,900. Teseq, www.teseq.com.
