EJ series

Compact bench top HV 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.
