Power Source Unit Ideal for MLCC Leakage Current

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, 500V / 1000V
power source for the Hioki SM7810 Super Megohm Meter, providing
positive and negative polarities required for MLCC test lines.

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 */channel allows for reducing the number of backup charges
* Output voltage of 1 kV is limited to 10 mA/channel
