COMPACT HIGH-VOLTAGE POWER SUPPLIES
- Max. Voltage: ±1 to ±2 kV
- Max. Current: 100 to 200 mA
- Max. Power: 200 W
- Reversible output polarity
Easy polarity switching via front panel
The EJ series features reversible polarity that can be controlled using a knob on the front panel. This allows users to switch output polarity safely and easily without the need for rewiring, significantly improving efficiency during testing applications. Please contact us for information regarding high-power models.

-
Dual Current Range
Switchable between 100% and 10% of Full Scale (F.S.).
Switching the range changes both the meter display and the external control signal scaling (0 to 10 V) to improve resolution for low-current applications.
Example: 200 mA F.S. switches to 20.0 mA F.S.
- -LN
-
Power Failure Recovery
Automatically restores the high-voltage output state when AC power is restored effectively resetting the protection circuit.
- -LZ
-
Carrying Handle
A handle is attached to the top of the unit for portability.
