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

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.
