Impulse Noise Simulator ( INS series )
Noiseken simulators to reproduce fast rise-up noises which are generated when switching ON / OFF electric current on the inductive load.
Since the pulse includes broadband frequency and its rise-up time is fast at 3ns or less, it can make the noise coupling dense and effective to reproduce the malfunctions of electronics equipment under the test.
It can realize performance evaluation of electronics equipments upon reproduction of line noises which are intruded to the power supply lines or induced noises onto the telecommunication lines.
Discontinuation notice of INS-4020 / 4040 and INS-AX2 series:In observance of the Minamata convention on mercury, products that include mercury have been restricted of export from Japan. This includes the INS-4020, INS-4040, INS-AX2 series that used a mercury relay switch, and now have been succeeded by the INS-S220 and INS-S420. Maximum output voltage of INS-S220 is 2kV, and that of INS-S420 is 4kV.

To solve the trouble in the market high frequency, energy volume of test pulse can be adjustable
Even narrow pulse with 50ns-100ns width contains less energy, twice fast transient due to rise and fall and inducted coupling occurred by sharp electromagnetic field effect electric circuit greatly.
Wide pulse with 800ns-1000ns contains more energy, so voltage fluctuation is easily to effect circuit.
The rise time of impulse simulator is faster than IEC61000-4-4 fast transient/burst test, so spectrum is high. When it injects noise to EUT, noise is easier to invade electric circuit internally.
Spectrum and amplitude is different due to Impulse width, so it is recommended to test with different pulse width.
Test reproduction is improved. More quantitative test is available.
The usual mercury relay changes into semiconductor relay, so test pulse stabability is improved. More quantitative and high reproduction test is available. Also, waveform distortion due to mercury relay's deterioration.
Mal-function rate is up. Test time is to be shortened.
The repetition of pulse in test is faster than the old product. Mal-function rate is up and test time is expected to be shortened.
Connection is simplified. Connection time is shortened.
Outlet panel to which EUT is easyily to be connected is adopted.
EUT is easy to connect by using outlet panel ( sold separately ) complying to each country's socket shape.

INS Test Setup Example
Method or test to power supply lines
①Connect power supply line for EUT to EUT LINE INPUT on the simulator main unit (hereafter called as main unit) through an isolation transformer
②Lay a ground plane and insulation sheet under main unit and EUT, and ground them for securing
③Connect power supply cable of EUT to main unit (Fold and bind the cable so it can be short in case the length is long)
④Connect short adaptor to SG. Connect SG terminal of main unit and FG terminal (In case it is there) of EUT to ground plane with low impedance braided wire shortly and securely
⑤Connect 50Ω TERM OUT connector to connector of phase (L1 or L2, PE if necessary) the noise is intended to be injected with coaxial cable
Method or test to interconnection lines
①Lay a ground plane and insulation sheet under main unit and EUT, and ground them for securing
②Open coupling adaptor CA-805B (Option) and clamp interface cable with the adaptor. Connect connector of the adaptor to PULSE OUT of main unit. Connect the one another connector of the adaptor to 50Ω TERM IN of main unit. In case for coupling adaptor CA-803A (Option), connect PULSE OUT of main unit and connector of the adaptor
③Connect power supply cable of EUT to arbitrary power source since no high voltage pulse is injected in this test
④Connect SG terminal and FG terminal of EUT to ground plane
