DESCRIPTION

Model 2594 is a high-stability high voltage power supply designed for the difficult requirements of focused ion and electron beam systems, featuring low ripple and stored energy. The low stored energy at the output reduces system upsets when arcing occurs. The low output ripple is the result of using sine wave excitation to the high voltage multiplier, as well as the use of a novel cancellation circuit. This avoids reliance on a large-value output capacitor.

The 2594 uses separate power return lines for the high voltage load, the input power, and the voltage programming reference. Separating these signals reduces unwanted interactions between the critical programming reference and the other circuits. It also reduces the 60 Hz noise that results from AC line power input.

NOTE: CPS also offers a 40 kVDC configuration for Model 2594. Certain specifications in the table below may only correspond with the standard 50 kV versions. Please call for further details regarding customization of this product.
