TREK PD04002A Versatile microprocessor-based charged plate monitor ideally suited to monitor the performance of air ionizers that are used in critical wide temperature operations. The ultra-sensitive Trek® PD04002A makes it the ideal choice in air ionizer monitor applications where small area ion collecting sensors are used to meet the requirement for high accuracy ion balance measurement to levels of less than one volt. The voltage of the charged plate is initialized prior to discharge time testing. Balance tests, positive discharge tests, and negative discharge tests can be initialized from a remote location through digital command signals. The Trek PD04002A utilizes a new technique that requires less than 0.1 picoampere of ion field current to achieve full accuracy and stability. Other product designs require up to 2000 times more ion current to be drawn from the ion field to achieve stability. PRODUCT HIGHLIGHTS ■ Utilizes standard, custom, and wide temperature range charged plates ■ High temperature charged plate (Trek PD04002AP) 25 x 25 mm (1 x 1 in) ■ Voltage monitor output for remote monitoring ■ Exceptional accuracy and stability ■ Compact design ■ Remotely monitor the charged plate voltage using a rear panel connection ■ Use on a table top or securely mount the monitor and charged plate with fasteners at the bottom of the unit ■ The voltage output at the Output “HI” terminal in reference to the Output “LO” terminal (ground) is a proportional buffered representation of the charged plate voltage at a scale factor of 1 to 22 (other scale factors are available). ■ CE compliant ■ NIST-traceable Certificate of Calibration provided with each unit Charged Plate Voltage Range 0 to ±55 VDC or peak AC, nominal Large Signal Bandwidth (-3 dB) DC to greater than 200 Hz Small Signal Bandwidth (-3 dB) DC to 2.5 kHz ©2020 Advanced Energy Industries,

1When the charged plate is at -55 volts, the voltage at the Voltage Monitor Output V HI is 0 V. When the charged plate is at 0 volts, the voltage at the voltage monitor is +2.5 volts. When the charged plate is at +55 volts, the voltage at the voltage monitor is +5 volts. 2These instruments are designed to make electrostatic voltage measurements only. Do not use this instrument to make measurements of "hard” voltage sources or voltage sources which can deliver currents high enough to cause harmful shocks or personal injury.
