The test generator CWG 2500 simulates high-energy interference pulses and is suitable for performing EMC tests on systems in accordance with the standards IEC / EN 61000-4-5, 2014 and VDE 0847 4-5. The CWG 2500 is a combined surge current / surge voltage generator that generates a standard open circuit surge voltage of 1.2 / 50 μs and a standard short-circuit surge current of 8/20 μs. The values for current and voltage are shown on the display, for evaluations with an oscilloscope BNC outputs for current and voltage are available on the rear.
With the built-in single-phase coupling network, the interference pulses of the hybrid generator can be coupled to the supply lines of the devices to be tested. The coupling takes place by means of discrete coupling capacitors. According to IEC 61000-4-5, 18 μF capacitors (balanced coupling) or 9 μF / 10 Ω (unbalanced coupling) are installed with sufficient dielectric strength. External coupling networks can also be operated via the HV socket or used for component testing.
The simple operation takes place via a capacitive color touch display. All parameters are clearly displayed without nested menus and can be changed quickly by tapping and using a digital rotary encoder. The normative test leve
