IEC61000-4-11 CSS-20P1 Voltage Dips and Short Interruption Generator
1. Introduction:
Voltage dips and short interruption generator is designed according to IEC6100-4-11, it is to simulate effects of abrupt voltage change, includes voltage dips and short interruption. The voltage dips and short interruption immunity tests are applied to electrical and electronic equipment having a rated input current not exceeding 16A per phase, and for connection to 50Hz or 60Hz AC networks. This is a basic EMC test to assess the immunity of equipment or a system against the voltage dips and short interruptions caused by fault in the network, primarily short circuits, in installation or by sudden large changes of load.
2. Features:
● Using 2 voltage regulators, the rated voltage can be adjusted and automatically stabilized, which can avoid the influence of power grid fluctuations on the test results. Simulate the test under 110V power supply. Can simulate the situation of power grid fluctuations under extreme conditions (such as the power supply voltage in remote areas is relatively high or low)
● Adopts 7 inch LCD touch screen, Waveform graphic display, easy to operation.
● EUT output comes with high-strength panel terminals, which makes the connection of test samples more convenient and reliable
● The instrument panel has external voltage and ammeter output, which is convenient to check the working status of the instrument.
