Duty Cycle
Under maximum-output settings and rated-load
conditions (30 ohm load), the energy platform is suitable
for activation times of 5 seconds on, 15 seconds o, for 1
hour. With lesser settings and loads, you can activate the
energy platform for greater durations without generating
excessive internal temperatures.

Maximum Output for LigaSure™ Mode
Power readouts agree with actual power into rated load to within 15% or 5 W, whichever is greater.
PRECAUTION: To avoid injury to the patient or surgical team, use only instruments rated for use at, or greater than, the
maximum peak voltages listed below. For example, bipolar instruments must have voltage ratings of 250 V peak or greater,
as shown in the “Open Circuit Peak Voltage (max)” column.

LigaSure™ vessel-sealing technology, an automatic adjustment, controls all modes. As tissue resistance increases throughout
the seal cycle, the energy platform modulates current and voltage until tissue resistance meets seal complete requirements as
needed by the tissue-sensing technology.
