Industrial process equipment has often been connected to controllers using RS232, RS423 or similar communication interfaces. These are unbalanced communication lines with low communication speeds up to 1 Mb/s that can only be used for relatively short distance communication due to their susceptibility to disturbance signals. CE testing using the combination wave/surge and ringwave impulses is required for products having this interface type. In special applications the damped oscillatory wave (DOW) will also be used.
Impulse generators cover the range 20 A for testing SPD devices up to 100 kA for testing high voltage varistors. Testing directly with AC power is possible with Coupling Decoupling Networks up to 1,200 Vac. All high voltage outputs can be covered with TC-ST test cabinet for personnel safety.
