- Maximum output voltage 15 kV (maximum coupling of 15 kV to AC / DC CDN and 6 kV to Telecom CDN)
  Enables to conduct the more extended reliability test including the destructive test
- Large size LCD for the operation is adopted for realizing better visibility and operatability
- Easy operation for the sequential tests with adoption of MPU control. Surge output / Waveform switching / Polarity switching / Sequence can be automated sequentially
- Selectable either MANUAL or PROGRAM mode MANUAL modes is used for the test according to the Standard or performing single conditioned test and PROGRAM mode can perform different conditioned tests sequentially so that the tests can be performed easily along purposes.
- Excellent safety with equipment of interlock
- Standard equipment of terminal for checking the waveforms：Enable to check the waveforms in connection to an oscilloscope with a BNC cable
- Isolation transformers available (Option)
- In order to avoid resonance with the power supply, possible to vary the constant of the decoupling network (1.5，1.3，1.0，0.8 mH) (Customized production). When some products like a power conditioner for photovoltaic application are connected to a lightning surge simulator, the resonant phenomena may occur and the products may not work well. In LSS-F03 series (with customization), possible to change constants of the inductances so as to avoid such problem
