PRODUCT FEATURES

• Digital Enable
  A BNC connection for a TTL compatible signal to turn on and off the high-voltage output is provided for each channel. A TTL high (or open) turns off the high-voltage output. A TTL low turns on the high-voltage output.
• Gain Control
  The DC gain of the Model PZD350A M/S is adjustable from 0 to 150 V/V.
• Dynamics Adjustment
  A graduated potentiometer is used to optimize the AC damping and response of the output signal for various load parameters.
• High-Voltage LED
  Front panel green LED illuminates when the high-voltage is on.
• Input Configuration
  The PZD350A M/S is factory configured as a noninverting amplifier. An inverting amplifier configuration is available. Specify when ordering or contact TREK, INC. for more information.
• Voltage Monitor
  A buffered output providing a low-voltage replica of the high-voltage output.
  • Scale
    1 V/100 V.
  • DC Accuracy
    Better than 0.1% of full scale.
  • Offset Voltage
    Less than 5 mV.
  • Output Noise
    Less than 10 mV rms (measured using the true rms feature of the Hewlett Packard Model 34401A digital multimeter).
  • Output Impedance
    Less than 47 ohms.
• Current Monitor
  A buffered output providing 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 25 mV.
  • Output Noise
    Less than 25 mV rms (measured using the true rms feature of the Hewlett Packard Model 34401A digital multimeter).
  • Output Impedance
    Less than 0.1 ohm.
• Power On LED
  Front panel green LED illuminates when the power is on.
• Limit Indicator
  An amber indicator will illuminate when the Model PZD350A M/S fails to produce the required high-voltage output such as from the Automatic Power Limit or output shorting.
