  • EJ series | High Voltage power supply Benchtop | Matsusada Precision

Compact bench top High Voltage power supplies with reversible polarity

  • Max Voltage: ±1kV to ±2V
  • Max Current: 100A to 200A
  • Max Power: 200W
  • Output polarity reversible type

Output polarity change by a switch on front panel even during high voltage output

EJ series is reversible polarity high voltage power supply featuring changeable polarity by a switch on front panel. Without rewiring, output polarity can be switched simply and safely. It improves operating efficiency. Please contact nearest sales offices for high power models.

Features and Benefits

  • Output polarity reversible type
  • Output polarity change by a switch on front panel
  • Polarity is changeable while High Voltage is on.
  • Suitable model for voltage withstanding test for diodes, power semiconductors, etc and for anodic bonding application
  • Microcurrent control by current range switching (Optional)
