The Trek Model 668B HVPS is a precision, high-voltage, reference power supply with an adjustable output voltage range of 0 to +3 kV DC or 0 to -3 kV DC and an output current capability of up to ±5 mA DC.
The HVPS front panel push-buttons are used to select the desired output voltage with 100 mV resolution. Each decade of the output voltage is independently controlled by its own set of up and down push buttons.
Current control is provided by front panel selection of either supply trip-off or limiting at the preset current value.
Nine programmable memory locations are provided for saving and recalling frequently used output voltage and current settings.
A voltage setting (including polarity) and a current limit or trip value can be stored in each memory location.
90 to 126 V AC or 180 to 250 V AC ±10%, at 50-60 Hz (specify when ordering).
