Automatic Power Limit
Automatically limits the internal power dissipation to protect the PZD2000A from overheating. The following graph illustrates the automatic power limit.

Model PZD2000A Output Operating Range

PRODUCT FEATURES

High-Voltage On/Off
Switch selectable for either local or remote control.

• Local
  Individual ON/OFF push-button switch.
• Remote
  A TTL compatible input. A TTL high (or open) turns off the high-voltage output. A TTL low turns on the high-voltage output.

Dynamic Adjustment
A graduated one-turn potentiometer is used to optimize the
AC response of the Model PZD2000A for various load parameters.

Current Limit/Trip
Switch selectable for either current limit or current trip. A graduated one-turn potentiometer is used to adjust the current limit or trip level from 10 to 200 mA.

Out Of Regulation Status
An indicator will illuminate and a BNC will provide a TTL low when the PZD2000A fails to produce the required high-voltage output such as during current limit.

Trip Status
An indicator will illuminate and a BNC will
provide a TTL low when the high-voltage output is disabled due to the output current exceeding the current trip level, the detection of a high-voltage power supply fault, or the removal of the top cover.

Fault Status
A BNC will provide a TTL low when the PZD2000A is out of regulation for greater than 500 ms.

Voltage Monitor
A buffered output provides a low-voltage replica of the
high voltage output.

• Scale
  1/200th of the high-voltage output signal.
• DC Accuracy
  Better than 0.1% of full scale.
• Offset Voltage
  Less than ±2 mV.
• Output Noise
  Less than 5 mV rms (measured using the true rms feature of the Hewlett Packard Model 34401A digital multimeter).
• Output Impedance
  47 Ω.

Current Monitor
A buffered output provides a low-voltage representation of the load current.

• Scale
  0.025 V/mA.
• DC Accuracy
  Better than 1% of full scale.
• Offset Voltage
  Less than ±10 mV.
• Output Noise
  Less than 10 mV rms (measured using the true rms feature of the Hewlett Packard Model 34401A digital multimeter).
• Bandwidth (-3db)
  DC to greater than 5 kHz.
• Output Impedance
  47 Ω.
