COMPACT HIGH-VOLTAGE POWER SUPPLIES
- Max Voltage: ±1kV to ±2kV
- Max Current: 100mA to 200mA
- Max Power: 200W
- Output polarity reversible type
Output polarity changes by a knob on the front panel even during high-voltage output
EJ series is a reversible polarity high voltage power supply featuring changeable polarity by a knob on the front panel. Without rewiring, output polarity can be switched simply and safely. It improves operating efficiency. Please contact our nearest sales offices for high power models.
FEATURES AND BENEFITS

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 the external signal (0 to ±10 V) is also changed. Example: 200 mA to 20.0 mA
- -LN
-
Output state auto-recovery (former: no power failure protection): High voltage output is turned ON/OFF by turning AC ON/OFF.
