IEC61000-4-5 EMC Test Equipment 10/700μs Combination Wave Generator
for Surge Immunity Test
1. Introduction:
LSG-6K20 combination wave surge generator is completely designed
according to IEC61000-4-5 and GB/T17626.5. The 10/700μs combination
wave generator is used to test ports intended for connection to
symmetrical communication lines. It is widely used in the fields of
industry control equipment, house-holding appliance,medical
electronics, communications electronics, components, auto control
equipment and etc.
Lightning surge generator is to simulate the surge voltage caused
by switching transient and lightning transient, the surge test is
to found out the surge voltage effect to EUT in normal working
condition.
The lightning surge generator can generates both 10/700μs, 5/320μs
combination wave. The test voltage is up to 6KV, user can choose
and define the test levels, built-in network with capacity 50V/0.1A
(DC). The parameters of open-circuit voltage waveform and
short-circuit current waveform are strictly meet the standard
requirements of IEC61000-4-5 and IEC60061-1.
2. Features:
1). 7 inches LCD touch screen, with plentiful functions, easy to
operation and update the software.
2). User can design the test program, and has 1000 groups memories.
3). Built-in 4 wires symmetric communication network, 2 in 1
design.
4).Intelligent program-controlled high voltage power supply with
built-in over-voltage, over-current and short circuit protection.
5). Add external network for more forms of communication line and
signal line or surge test
6). Intelligent judge the abnormal of high voltage and surge
output.
