Power Source Unit Ideal for MLCC Leakage Current Measurement

The SM7860 series allows for setting the dual-line output voltage on 8 channels or 16 channels, and enables up to 32-channel of output. The Hioki SM7860-5x/SM7860-6x series is a 32-channel, 500 V/1000 V power source for the Hioki SM7810 Super Megohm Meter, providing positive and negative polarities required for MLCC test lines.
See the brochure for SM7860 Functions & output channel configuration.

Key Features

  • Support for multi-channel systems up to 32-channel output
  • 8-channels or 16-channels dual-line output voltage setting
  • Positive and negative polarities required for the MLCC test line included in a single unit
  • Output ON/OFF and current limitation can be performed for each channel
  • Support for the discharge of the charge capacitor
  • Output voltage of 1 kV is available
  • Large current output of 50 mA (*1)/channel allows for reducing the number of backup charges
  • *1:Output voltage of 1 kV is limited to 10 mA/channel
  • *2:Output terminal cable
