These Agilent Varian 4UHV ion pump controller with part number 9299100 have one high-voltage HV channel providing 120 Watt at negative polarity (1 x 120 W Negative Polarity). It is important when ordering to be informed that the 4UHV ion pump controller can be purchased with up to four high voltage channels in different output power ratings with a maximum sum total power of 400 Watts. It is also important to know that the output polarity is NOT field adjustable on these 4UHV controllers, you must select an appropriate part number with desired output polarity, e.g., (Diode & Noble Diode) need positive voltages, while Triode style elements (old style Triode & StarCell) need negative voltages for operation. All part numbers of the Agilent Varian 4UHV ion pump controllers operate on 100 - 240 VAC input power and have the Fischer HV connector and are designed to work continuous duty with the medium and large ion pumps, e.g., 20, 40, 55, 75, 150, 300, & 500 l/s pumps.

These Agilent Varian 4UHV ion pump controller with part number 9299010 have one high-voltage HV channel providing 200 Watt at negative polarity (1 x 200 W Negative Polarity). It is important when ordering to be informed that the 4UHV ion pump controller can be purchased with up to four high voltage channels in different output power ratings with a maximum sum total power of 400 Watts.
