Power Boost
Power Boost is the reserve power available
constantly that allows reliable startup to
support sudden and short spike of loads
with high inrush current typically during turn
on to remove the need of more expensive
higher rated power supply unit. After the
output has reached its steady state set
value, the power supply can support surge
loads with a higher short-term power
demand up to 200% of maximum rated load
(IO Max), for a maximum duration of 2
seconds, or 150% of maximum rated load
for a maximum duration of 5 seconds. The
Power Boost is also available to repeatedly
basis with according to the condition of an
average (R.M.S) output power shall not
exceed continuous operating condition or
refer to duty cycle calculation below.

It is not recommended to prolong the duration of Power Boost to be longer than the specified duty cycle calculation, this may cause
damage to the PSU.
