CliQ II DIN Rail Power Supply
24 V 120 W 3 Phase / DRP024V120W3B
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 150%
of maximum rated load (I

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

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, L2 and L3 pins, which have been tested and approved on 20 A (UL) and
16A (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, a minimum value of 13 A B- or 6 A C-
characteristic breaker should be used.
All parameters are specified at 25°C ambient and AC input unless otherwise indicated.
