Model INS-S220 / S420 -Impulse Noise Simulator
To solve the real trouble in the market. This Noise simulator simulates high frequency noises generated by ON/OFF switching at contact points of switches or relays, and arcs caused by electric motor, allowing to evaluate the resistibility of electric devices. The Pulse contains wide range of frequency components and energy volume is changeable by adjusting pulse width. This allows conducting of highly-reproducible noise tests for noise troubles in the market.
To solve the trouble in the market Test pulse with adjustable high frequencies and energy volume
Narrow pulse of 50-100ns width although contains small energy, greatly affects electric circuits due to two transient fluctuations of short-time rise and fall and inductive coupling by steeply generated electromagnetic field.
Improved reproducibility of test results Allows for more quantitative testing
By changing from the conventional mercury relay to the semiconductor relay, the stability of the test pulse waveform has been improved, enabling tests with more quantitative and highly reproducible test results than before.
Improved malfunction occurrence rate Contributes to testing time reduction
By speeding up the test pulse repetition period compared to old models,product malfunction occurrence rate should increase contributing to overall test time reduction.
Pulse Widthsetting simplified Setting time reduced
Pulse width setting in old models (INS-4020/4040) required troublesome manual cable connection switching.
Connection simplified Connection time reduced
Outlet panel was adopted for easy EUT connection.
Operating Cost reduction Consumable parts reduced
Adopted semiconductor type relay instead of old mercury type relay (consumable).
Easy Noise countermeasurement Identify the malfunction location
A large number of noise application options are available for power lines, communication lines, harnesses, housings, and board levels, making it easy to identify malfunction locations.
