Coil pulse meter, coil insulation measurement EGC-KOKUSAI DWX-300LI DWX-01LI

Producer: EGC-KOKUSAI

Category: Electronic industry measuring machine Tags: DWX-01LI, DWX-300LI

With advanced requirements for miniaturization and high frequency technology of coil products, DWX tester is designed to test other coils and low inductance used in high-end electronic components . Through the use of a pulse source with high-speed switching, a high-efficiency input circuit, and a high-speed A/D sampling circuit, the DWX tester can provide a new solution for inductor tests. short.

Máy đo cuộn cảm siêu thấp, tốc độ cao, cuộn dây 1μH được kiểm tra trong 10ms. Máy có thể dùng để đo cách điện cuộn dây.

The model is specialized in the insulation test of chip power inductor coil.

4 terminal testing circuits can be performed sufficiently with applied high voltage to ultra-low inductance coil. Maximum of 1000v (shown on screen) impression is possible to a minimum of 1μH coil.

Detailed response waveform is displayed as twice as many wave-form sampling resolution by testing machine.

High-speed test can be done with shortest test time of 30msec with 1 pulse application, and mass-production in line is possible. Each function of a test mode” and the “breakdown test mode” which performs detailed evaluation is carried in one set.

Impression of one pulse, high-speed test can be done without a judgment in shortest test time of 10msec, and mass-production line is possible.

It also suits to a choke , motor coil, and coil with few numbers of turns besides a chip power inductor.
