Tube Sealer Power Source
6
The Power Source generates RF power, the frequency of which is controlled
by a solid state oscillator/amplifier operating at 40.68 MHz. The RF energy level
and seal time are controlled by means of a proprietary solid state circuit design,
allowing various tubing sizes to be automatically accommodated. Additionally,
a built-in arc detect mode will normally preclude sealing if the tubing exterior,
ground jaw and/or RF jaw surfaces are affected by contamination and/or
moisture. Thus, the Model 2380 Tube Sealer requires no manual power or
timing adjustment by the user.
The Power Source will automatically detect a battery low condition, notifying
the operator of impending seal deterioration via visual and audible indications.
This detection circuit is activated when the battery voltage has dropped to a
point in which a limited number of good seals remain.
