EFT and Surge Generator
1. Introduction
EFT and Surge Generator is applied to check the performance of the power cable and inner electrical circuit of equipment (home appliances, communication electronics, electrical components, auto control system and etc.) against the high energy transient interference caused by switching and lightning transients. The equipment meet the requirements of IEC61000-4-5 and IEC61000-4-4.
Burst and surge generator is a 2 in 1 equipment, it can do both the fast transient immunity test and surge immunity test in an economic way.
2. Features:
1) 7 inches LCD touch screen, with plenty of functions, easy to operation
2) 1000 groups memories
3) Surge voltage and current waveforms can be monitoring at real time by connect with an oscilloscope.
4) Built-in single phase 10A (16A) network, 2 in 1 design.
5) Equip with industrial standard socket-outlet for EUT.
6) Buit-in working voltage and current monitoring.
7) Over-voltage, over-current and short-circuit protection
8) Alarm at voltage error and no output
9) It has self-diagnosis function, can judget obnormal high voltage and surge output.
