Discontinued – Replaced by 307 Series 307 Series Suggested List Price: $1,395.00+ (OEM 03/27/09 MQF) Catalog Number: 303007 Serial Number : 1849 Manufacture Date : A8 Options : Analog & Convection w/ Cooling Fan Electrical : 115V, 50/60Hz, 3.0A SB Copy of the User Manual is Included. Equipment Description: The Series 303 Vacuum Process Controller (VPC) is a programmable, microprocessor controlled vacuum system controller. The basic VPC operates two ionization gauge tubes over the range from 5 x 10 to 1 x 10 Torr. There are two basic VPC models; VOCA and VPCB. VPCA sequentially operates two ionization gauge tubes, while VPCB is configured to simultaneously operate two ionization gauge tubes. Both VPC and VPCB front-panel controls and indicators are identical and allow the operator to program gauge tube sensitivity, electron bombardment degas power, degas time duration, gauge tube filament overpressure trip, direction/rate of change arrows, two-or-three-digit pressure readout, and security of programs against change. Also a control is provided for maximum emission current selection and indicators for leak testing and gauge tube filament circuit deterioration warning. The operational capability of a basic VPC can be upgraded by the installation of plug-in option cards. A VPCA or VPCB can be ordered with the desired options installed or the user may order and easily install the desired plug-in options. Eight card slots are provided for installation of the option cards. Installation procedures for the option cards are provided in Chapter 2 of the User Manual. Specifications: Electrical Voltage: 90-110/105-125/195-235/210-250 VAC rear panel selectable Frequency: 50Hz or 60Hz Power: 450W (maximum) Environmental Operating Temperature: 0 to 40°C (32 to 104°F). Warranted specifications given at 25°C ± 5°C. Physical Dimensions: 19W x 3.5H x 18D (48.3 x 8.9 x 45.7cm) Weight: 25lbs (11.6kg) not shipped Gauge Type: Baynard-Alpert type, or evquivalent, ionization gauge Pressure Range: 5 x 10 to 1 x 10 Torr; 7 x 10 to 1.3 x 10 mbar; 7 x 10 to 13Pa Gas Type: Direct reading for air, N2 or Ar. By altering the tube sensitivity in the N2 mode, other gas types can be measured directly. Accuracy of electronics measurement: Typically ±2% of pressure reading over the range 10 to 10 Torr (mbar) or 10 to 10 Pa Resolution of Ionization Guage (IG) Readout: ±0.1% of full scale in each decade, over the range (IG) readout 10 to 10 Torr (mbar) or 10 to 10 Pa; ±1% of full scale in the 10 Torr (mbar) or 10 Pa range; ±10% of full scale in the 10 Torr (mbar) or 10 Pa range Display Update Time: 0.5 second maximum for all ranges Programmable IG Tube Sensitivities: 0.1 to 99.9/Torr; 0.1 to 99.9/mbar; 0.001 to 0.999/Pa; Factory Set at 10/Torr Emission Current: User programmable to maximum values of 1, 2, 4 or 10mA. Factory set at 4mA. Controller selects one of the following constant emission currents, subject to the maximum value programmed, to optimize performance at a given pressure 0.01, 0.02, 0.04, 0.1, 0.1, 0.4, 1, 2, 4, 10mA. The emission can be fixed to the selected maximum value. This will limit pressure measurement range. Collector Potential: Zero V referenced to system ground Grid Potential: 180 ±10VDC referenced to system ground (adjustable) Filament Voltage: 2.0 to 8.5VAC RMS Filament Current: 6.0A RMS (maximum) Filament Bias: 30 ±4VDC referenced to system ground Degas Power: Electron bombardment. 5 to 80 watts, programmable in 5 watt steps. Power can be displayed during degas. Degas Pressure: Must be less than 5 x 10 Torr. Approximate pressure can be displayed during degas. Time: Programmable from 1 to 999 minutes, in one minute steps, or manually or remotely timed. Degas time remaining can be displayed. Start: Soft start – Start manually or with remote signal. Stop: Manually or remotely timed. Grid Potential: 500VDC effective. Measured with respect to filament. Emission: 10 to 160mA Input Functions: IG1 On/Off, IG2 On/Off, Degas 1 On/Off, Degas 2 On/Off Current: 1mA to ground Contract Form: Single pole, double throw Contact rating: 2 @ 250VAC resistive load For More Pictures Please Click the Following: Picture 2 Picture 3 The charge for freight will be determined by the destination upon the ending of the auction.
