RF POWER OUTPUT
2.3.1
Output Level
The power output in the CW (CUT) mode is 120 watts into (500 ohm) a matched load.
2.3.2
Output Level Stability
The output is adjustable from less than 5W to maximum with little change in slope.
2.3.3
Power Output Stability
Impedance range of 50 ohms - 2K at any power setting or waveform setting.
2.3.4
Power Output Level Stability
Once enabled, the output remains constant /-10% turn on for a period of 10 seconds.
2.3.5
Power Output Purity
In the CW CUT mode harmonics and spurious are at least 20dB below the reference output for
any load impedance in the range of 50 ohms to 2K ohms.
2.3.6
Frequency Accuracy
The output frequency is maintained at 4.0 MHz +/- 400Hz over all service and loading conditions
including short and open for monopolar mode.
2.4
MODULATION (WAVEFORMS)
FOUR OUTPUT WAVEFORMS ARE PROVIDED.
2.4.1
CW CUT
Continuous wave output with average power equal to the maximum with no deliberate modulation.
2.4.2
CUT/COAG
Deeply modulated envelope with average to peak power ratio approximately 50%. Modulation
occurring at 120 or 100 Hz rate.
2.4.3
HEMO
Deeply modulated square wave with average to peak ratio approximately 35% Modulation
occurring at a 60 or 50 Hz rate.
2.4.4
FULGURATE
Deeply modulated wave with average to peak ratio to 10% or less. Modulation occurring at random
rate but no greater than 1 KHz.
2.5
TIMING
The suggested operational duty cycle is 10 sec. ON/ 30 sec. OFF. The yellow indicator will be ON when
CUTTING MODE circuit is energized. And the blue indicator will be ON when COAGULATION MODE
circuit is energized. The unit will “beep” continuously when ON with a tone after 55 seconds of applied
power at any level and in any mode. It shall change after 55 seconds and turn off after another 5 seconds.
2.6
CLASSIFICATION
2.6.1
According to the type of protection against electrical shock: the equipment is energized from an
external electrical power source and is Class I equipment.
2.6.2
According to the degree of protection against electric shock: Type BF equipment.
2.6.3
According to the degree of protection against harmful ingress of water: ordinary equipment.
2.6.4
Cleaning, Disinfecting and Sterilizing the Unit and Accessories
2.6.4.1
Cleaning and Disinfecting the unit:
Cleaning and disinfecting of the unit should only be done with nonflammable and
nonexplosive agents. Make sure that no moisture or detergents enter the unit. If
