Automatic Power Limit
Automatically limits the internal power dissipation to protect the Model P0621P from overheating. The following graph illustrates the Model P0621P automatic output power limit range (at ±20 mA current limit potentiometer setting).

Model P0621P Output Operating Range

PRODUCT FEATURES

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

• Local
  Individual push buttons.
• 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 used to optimize the AC response of the P0621P under various load parameters.

Current Limit/Trip
Switch selectable for either limit or trip. A graduated one- turn potentiometer is used to adjust the limit or trip level from 0 to 20 mA.

Out Of Regulation Status
A yellow indicator will illuminate and a BNC will provide a TTL low when the P0621P 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 or by the removal of the top cover.

Fault Status
A BNC will provide a TTL low when the P0621P is in out of regulation for greater than 500 ms.

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

• Scale
  1/3000th 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 20 mV rms (measured using the true rms feature of the Hewlett Packard Model 34401A digital multimeter).
• Output Impedance
  47 Ω.
