  • Description
  • LS8815 impulse winding tester is specially designed for the testing needs of winding components, using a high-voltage charging small capacitor (low test energy) and the coil to be tested to form RLC parallel resonance, by the oscillation attenuation waveform, through up to 100Msps (can be customized 200Msps) and precision sampling processing analysis technology. It can test the poor self-insulation of the coil (inter-turn short circuit, inter-layer short circuit, insulation performance reduction, etc.), so that component manufacturers and users can be more effective for product quality control.

    LS8815 series are with fast measurement speed, good repeatability of the test waveform. It can be widely used in motor, power frequency transformer, relay, switching power transformer, degaussing coil and other wire wound components. LS8815 series can be used in automated test systems to greatly improve test efficiency.

    The following are product models and differences, please purchase on demand:
    • LS8815-3KV pulse voltage output: 100-3000V
    • LS8815-5KV pulse voltage output: 100-5000V
    • LS8815-10KV pulse voltage output: 100-10000V
    • LS8815S-8 8-channel test, pulse voltage output: 100-5000V
