RF Power Products (RFPP) / Plasma-Therm HFS-15000D High Power RF Generator Comes with what you see in the pictures. If you don't see it, you probably wont get it. Specifications are from RFPP and may vary slightly due to upgrades, options, or revisions this unit may or may not have. The Unit's Serial Number Tag Reads: Model Number: HFS-15000D 7800003030 SE#100 Power Requirements: 208 VAC, 3 Phase, 85 Amps Hour Meter Reads: 38821.04 hours * Conservatively rated for continuous duty. * Metering provided for all RF circuits. * Protective devices for air flow, preheating, excessive VSWR, DC overloads and overtemperature. * Indicating lights describe equipment status. * Meets or exceeds FCC requirements for ISM bands. * Designed for remote control operation. * Common exciter input provision. These high power RF generators represent a second generation in the development of reliable sources for industrial applications. The inclusion of the AUTOMATIC POWER CONTROL SYSTEMS and VSWR PROTECTION DEVICES makes them a must for modern production lines. These features permit a high level of sophistication in the automatic operation including insensitivity to power line variations. All units are self-contained in cabinets that incorporate heavy-duty casters to assist in positioning and moving. All controls, meters and indicator lights are accessible from the front, however, only those required for actual routine operation are readily available to the operator. Controls required by maintenance and service personnel are recessed and covered to avoid operator error and confusion. Access to the equipment can be had by removing the front, (interlocked) covers or by opening the rear interlocked hinged door. Cooling is achieved by utilizing a high pressure blower which draws air through a rear filtered panel and exhausts via ducts on the top of the equipment. Most parts are standard catalog items, no attempt has been made to remote the manufacturer's numbers. Thus, most replacement parts can be obtained from local distributors, although RF Power Products maintains a complete inventory. All panels are constructed of iridited aluminum to insure excellent conductivity. The front panels are finished with a light gray semi-gloss baked enamel paint. Cabinets are painted with a highly resistant durable blue textured vinyl. The generator consists of a conventional crystal controlled oscillator and a series of RF amplifiers. Each of these stages is operated well below its maximum capability, thus the unit can achieve an extra 10% power output on a continuous basis without any reduction in tube life or reliability. The Intermediate Power Amplifier (IPA) is a very conservatively rated pentode. This tube is capable of achieving 3kW output. Thus, the drive requirement of this stage is very easily obtained. The first three stages are the same for all units. The final amplifier stages are high-mu zero bias triodes manufactured by a leader in this field. These tubes have power gains of approximately 20 and operate with the control grid contacted directly to DC ground, insuring stable high power operation. They can achieve the output power of the generator with less than 50% of the RF drive available. Because of the isolation between the input and output circuits, the coaxial construction of the tube and the high degree of shield of the grounded grid circuitry arrangement, there is no need to neutralize this stage. The automatic power control system can be switched on to "hold" below a limit of incident or reflected power. It automatically adjusts the drive to the final stage of the equipment such that the power will not exceed the present maximum value. The same device can be set to automatically limit the power delivered to the load. This revolutionary control system accepts external signals which can be used for programming generator output. The manual power output control of the generator is available on the front panel of the equipment. The control circuitry of the generator is designed so that the equipment can be operated by remote control. All power supplies of the equipment utilize field proven silicon rectifiers with substantial reserve in both PIV and current rating. There exists within the generator a number of overload relays which are placed in critical circuits. The operation of these overload relays will remove the plate voltage from the equipment in less than forty-five milliseconds after an overcurrent is sensed. Each relay is associated with a latching indicator light that denotes the circuit where the overload has occurred. Frequency/With Stability: 13.56 MHz ± .05% (0°C to 50°C) Dimensions: 70" H x 35" W x 37" D (52 cubic feet) Forward Power Regulation: ± 1% Line Voltage (Input Power): 208 VAC, 3 Phase, 85 A Interface Connectors: MS3102A22-14S Output Connectors: 1 5/8 EIA Flange Adapter to Type LC provided with generator Cable Requirements: LDF5-50A For More Pictures Please Click the Following: * Picture 3 - Multimeter and Amp Meter * Picture 4 - RF Power Meters * Picture 5 - PA Tuning and Loading Controls * Picture 6 - Front Operation Controls * Picture 7 - Front Panel Removed #1 * Picture 8 - Front Panel Removed #2 * Picture 9 - Front Panel Removed #3 * Picture 10 - Front Panel Removed #4 * Picture 11 - Back Door Open * Picture 12 - RF Section with Back Door Open and Panel Removed * Picture 13 - High Voltage Hook on Back Door * Picture 14 - Interface Connections on Back * Picture 16 - Serial Number Tag (this posting is the responsibility of the poster) |
