Agilent Varian MiniVac Ion Pump Controller, 21 Watts, King HV Connector, 24 VDC, PN 9290197
In Stock: 1


Agilent Varian MiniVac Ion Pump Controller, 21 Watts, with King HV Connector for Small Mini Ion Pumps 0.4, 2, 8, & 10 l/s, 24 VDC Input Agilent PN: 9290197 This Agilent Varian MiniVac ion pump controllers, part number 9290197, operates on 24 VDC input power and have the Kings HV connector which is designed to work with the small ion pumps, e.g, miniature 0.4, 2, 8, & 10 l/s. This is important when ordering, there are different part numbers for MiniVac controllers which are used to operate larger ion pumps, e.g., 20, 40, 55, 75, 150, 300, & 500 l/s pumps. It is also important to order the correct cable that can be used with this part number 9290197 MiniVac controller, we will provide a list of compatible cables below. The output voltage polarity is a selectable parameter with Mini Vac ion pump controllers, they can be field set to + or - to match your ion pump polarity requirement; (Diode & Noble Diode) need positive voltages, while Triode style elements (old style Triode & StarCell) need negative voltages for operation. The Agilent Varian Mini Vac ion pump controllers are small and compact being cost-effective with a low 21 Watt output (3 kV @ 7 mA). They can be used to operate all the Agilent Varian ion pumps, models include, mini, 2, 8, 10, 20, 40, 55, 75, 150, 300, through 500 l/s pumps. However, the starting pressure requirement is much lower for the larger ion pumps to reduce the start up current requirement. How much power do I need for my ion pumps? Power requirement depends on the pump size and starting pressure; the larger the pump and higher the starting pressure, the higher the power consumption. The largest standard Ion Pump configuration, 500 l/s, can be easily started with 200W up to 1-5 mbar, while a medium size pump (75 l/s) needs less than 80 W to be started at the same pressure, and 80 W are sufficient to operate a 500 l/s in the typical Ion Pump operating range (below 2-6 mbar). Why was the higher power rating necessary in the past? In the past ion pumps were started with the aid of sorption pumps, able to reach 10-4 mbar only. As a consequence, much larger and more powerful Ion pumps controller were needed. The resulting life of Ion Pumps started at such high pressures was much shorter (1 minute of operation at 10-4 mbar is equivalent to 2 months at 10-9 mbar) Today’s oil-free turbo pumps, backed by oil-free primary pumps, achieve lower pressures, thereby reducing the starting pressure of the ion pump. This reduces the maximum power requirement of the ion pump controller and extends the lifetime of the ion pump. Negative or positive? The requirement of negative or positive potential depends on the pumping element installed in the ion pump. Diode style elements (Diode & Noble Diode) need positive voltages, while Triode style elements (old style Triode & StarCell) need negative voltages for operation. As stated above the output voltage polarity is a selectable parameter with Mini Vac ion pump controllers, they can be field set to + or - to match your ion pump polarity requirement (see user's catalog section below). General info about Agilent Varian MiniVac series ion pump controllers The MiniVac ion pump controller is designed to economically operate any Vaclon Plus type and size: Diode, Noble Diode, and StarCell, from Miniature to 500 l/s pumps. The MiniVac is very compact and light, can be operated in local or remote mode, and is suitable for high radiation environments. Medium pumps (Vaclon Plus 20 to 75) can be operated at any pressure below 1 x 10-5 mbar (continuous operation). Large pumps (Vaclon Plus 150 to 500) can be operated at any pressure below 2 x 10 -6 mbar (continuous operation). The MiniVac is designed to withstand continuous operation at short circuit conditions, without damaging the ion pump or itself. A 24 V battery-operable version is available for portable application Compatible cables - For Agilent Varian MiniVac ion pump controllers, part number 9290197, operates on 24 VDC input power and have the Kings HV connector which is designed to work with the small ion pumps, e.g., miniature 0.4, 2, 8, & 10 l/s. 9240122 Agilent Varian HV Cable for Mini VacIon Miniature Ion Pumps, w/ King HV Connector, 8 ft 9290706 Agilent Varian HV Bakeable Cable for 2 l/s Ion Pumps, w/ King HV Connector, 13 ft Long 9240741 Agilent Varian HV Cable for 8 & 10 l/s VacIon Ion Pumps, w/ King HV Connector, 10 ft.
