EIMAC TUBES Vs. MKS ( CHINA TUBES)
I have done extensive study on RF tubes. EIMAC is far the best long lasting MEDICAL grade tube we use in all amplifiers repairs. If you want to know more about why tubes have different part numbers on them, please call me.
WE ARE THE BEST IN THE BUSINESS IN THE SERVICE AND REPAIR OF ALL MKS RF AMPLIFIERS. OUR ENGINEER, WHO HAS OVER 40 YEARS IN THE RF INDUSTRY WITH 6 OF THOSE YEARS WORKING DIRECTLY IN THE DESIGN, BUILD AND TESTING OF ALL MKS RF AMPLIFIERS. CERTIFIED BY THE MANUFACTURE.
All our MKS units use only EIMAC tubes which we offer a 1 year warranty. Many of our competitors and even MKS uses China made tubes which don’t last and the gain drifts.
FREQUENCY: 42.57MHz
OUTPUT: Typical gain at 15 kW output will be 71.8 dB
MAIN INPUT~ 32A/208-230V 50/60Hz
COMPLIES TO 1 EC 601-1 CLASS 1
This unit has been fully refurbished with all the upgrades and new EIMAC tubes. We don’t use factory MKS tubes for many reasons and 100% of all our customers request that we only use EIMAC.
Always ask if the new or refurbished system comes with EIMAC or MKS (Made in China)
We do warranty our tubes for 1 year or 3000 hours whichever comes first.
The amplifier is linear and fully automatic. It is capable of delivering up to 25 kW (64 MHz) or 15KW (42 MHz) into a load VSWR of 1.5:1. Typical gain at 25 kW output will be 74 dB; typical gain at 15 kW output will be 71.8 dB.
The amplifier consists of a four-stage solid-state preamplifier/driver followed by a two‑stage, grounded‑grid, vacuum-tube amplifier. The vacuum-tube stages provide approximately 25-dB gain. The balance is supplied by the solid-state preamplifier/driver.
All major functions are controlled and monitored by a microprocessor (uP) based control system. The uP provides amplifier and MRI system protection from excessive average- and peak-power operation. The amplifier is remotely controlled via a serial interface during normal MRI system operation.
PRODUCT DESCRIPTION
Used in the 1.0T MRI RF amplifier, the models 53-S23A-64 and 53-S24A-42 are linear, pulsed, RF power amplifiers intended for use as part of a Magnetic Resonance Imaging (MRI) system.
These models are Class 1, type B, ordinary equipment without applied parts. They are to be used
in an area where no flammable anesthetics or gasses are used.
Both models are UL Listed under UL 2601/ CSA 601 (file #E199620). Both have been
investigated for compliance with the International Electrotechnical Commission Standard for
Medical Electrical Equipment, IEC 601-1.
The individual amplifiers do not comply with EMC requirements until the unit is installed in the
MRI system. Verification of EMC compliance must be done after system installation.
Each amplifier must be enclosed in an outer cabinet when operated in patient vicinity.
SAFETY CONCERNS
The amplifier must be installed, operated, and serviced by qualified personnel.
The model 53-S23A-64 is capable of delivering in excess of 25,000 watts peak RF power at 64
MHz into a 50-Ohm load. The model 53-S24A-42 is capable of delivering in excess of 15,000
watts peak at 42 MHz. These power levels can cause severe RF burns and other injuries if
misused. Never operate the amplifier without properly terminating it with a suitable load.
The user accepts full responsibility for the proper use of the amplifier and for all safety issues
concerning the use of RF power for medical purposes.
SAFETY WARNINGS
LETHAL VOLTAGES ARE PRESENT INSIDE THE AMPLIFIER. DO NOT OPERATE
THE AMPLIFIER WITH THE COVERS REMOVED. CONSULT THE
MANUFACTURER BEFORE ATTEMPTING TO SERVICE THE AMPLIFIER.
DO NOT PLACE HEAVY OBJECTS OR LIQUIDS ON TOP OF THE AMPLIFIER.
DO NOT BLOCK THE AMPLIFIER COOLING AIR INTAKE OR EXHAUST PORTS.
UNITED RF, LLC IS NOT RESPONSIBLE FOR
INCORRECT INSTALLATION, APPLICATION, USE, OR FOR PATIENT SAFETY WHEN
THIS AMPLIFIER IS USED IN A MAGNETIC RESONANCE IMAGING OR OTHER
SYSTEM.
