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.
External Input Protection Device
The unit is protected with internal fuse (not replaceable) at L1 and L2/N pins, which have been tested and approved on 20 A (UL) and
16 A (IEC) branch circuits without additional protection device. An external protection device is only required if the supplying branch
has an ampacity greater than above. Thus, if an external protective device is necessary, or, utilized, please refer a minimum value of
16 A B- or 8 A C- characteristic breaker.
Fig. 3 Duty Cycle Calculation
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 120% of maximum rated
load (I
O
Max), for a maximum duration of 3
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.
