Trek 156A
Charge Plate Monitor for Evaluating the Performance of Air Ionizers Used to Neutralize Static Charges
Advanced Energy’s Trek 156A tests the efficiency of an ionizer’s ion production by timing how long it takes air ions produced to discharge a floating plate that has been pre-charged to either a positive or negative value.
- Monitored Voltage Range: 0 to ±1100 VDC or peak AC
- Large Signal Bandwidth: (-3dB): DC to 10 Hz
- Decay Mode Thresholds: Programmable from 1 to ±1000 V in 1V increments (accurate within ±1V of programmed voltage)

Overview
The Trek® 156A tests the efficiency of an ionizer’s ion production by timing how long it takes air ions produced to discharge a floating plate that has been pre-charged to either a positive or negative value. The Trek 156A also tests the balance between positive and negative air ions by measuring the offset voltage generated on a floating plate due to an imbalance of positive and negative air ions impinging on the plate from the ionizer.
Typically, as an ionizer ages, the rates of positive and negative air ion production decline. Consequently, the time required for the ionizer to neutralize static charges increases, and the balance of positive and negative air ions changes. The neutralization (decay) time may become too long for the ionizer to fully neutralize charges that are generated at a work location, or the ionizer may begin to charge objects that were initially uncharged.
