HIGH VOLTAGE BIPOLAR AMPLIFIER
High Voltage of 1000V, Fast Response of 10kHz
- Voltage range: ±0.5kV, ±1kV
- Current: 50 to 200mA
- Frequency bandwidth:
DC to 10 kHz (at CC mode) - High-speed response
High Voltage/Fast Response Four-Quadrant Bipolar Amplifier
DOC series is ±500 V/±1000 V high voltage four-quadrant bipolar amplifier. With its feature of voltage limit and current limit setting at will. It will drastically reduce the risk of applying excessive stress on your load. The output terminal is available on the front panel for excellent operability.
FEATURES AND BENEFITS
- High voltage output up to 1000V
- Compact, High voltage, and High power
- Four-quadrant output (Source and Sink are available.)
- CV (constant voltage)/CC operation (constant current) is selectable.
- Universal AC input supported
- High-speed response, 10 kHz

Automatic output recovery (previous: no power failure protection)
This option retains the output state when recovering from an input power interruption, such as an AC power switch ON/OFF or a power failure. Therefore, there is no need to reset the protection status by turning off the OUTPUT switch once.
Caution: If you turn on the power while the OUTPUT setting is ON, the output will be ON.
How to Order
When ordering, add "-LN" after Model No.

Tech Notes
Capacitive Load
When a capacitive load is more than 100 pF (including a stray capacitance of output wire), the resonance in the output may occur. In that case, install 100 Ω (at 0.1 μF) to 1000 Ω (at 1000 pF) of high-voltage resistance in the output in series. Please note that the frequency band is limited when using an amplifier with a capacitive load, as shown in the formula on the right.
In addition, when an amplifier is used for a corona discharge, a current higher than its rating will flow, and it will affect the amplifier badly. In this case, as well as when using an amplifier with a capacitive load, please install the output resistance and limit the current.
* Please avoid continuous input of the high-frequency signal, which reduces the output frequency of an amplifier. An amplifier will break because of an increase in internal loss.
