Compact bench top High Voltage power supplies with reversible polarity

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

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

EJ series is a 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
  • Microampere control by current range switching (Optional)

Options

-LG

Connector for GPIB, RS-232C, RS-485, USB, LAN Interface

(CO-HV adapter is required. Please refer to CO/USB series datasheet for details.)
-LCr

Current range change

100% ⇔ 10% F.S.

With the current range switching, the display of output current in full scale is changed. Example: 200 mA to 20.0 mA
The full scale value of external signal (0 to ±10 V) is also changed. Example: 200 mA to 20.0 mA

-LN

No protection against power failure

AC output is tuned ON/OFF by turning AC ON/OFF.
-LZ

Handle

Carry handle

How to Order

Digital remote control adapter

LAN / USB / RS-232C / RS-485 / GPIB Control

To remotely control this high-voltage power supply via LAN or USB, purchase both an digital converter (CO-HV) and optical isolation adapter. The digital converter (CO-HV) converts the analog control signal of the high-voltage power supply into a digital optical signal. The optical isolation adapter converts interface signals such as LAN and USB to optical signals.

For details, check the CO / USB series for a digital converter (CO-HV) and optical isolation adapter.

  • Optical isolation
  • 16-bit (1/65535) high-resolution A / D .
  • Computer and PLC controlled.
  • Protecting from discharge and surge.
  • Ideal for automation and labor-saving systems.
