TECHNICAL DATASHEET
CliQ II DIN Rail Power Supply
24V 480W 1 Phase / DRP024V480W1B
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
(I
Max), for a maximum duration of 2
O
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.
External Input Protection Device
The unit is protected at the L pin, with an internal fuse that cannot be replaced. The power supply has been tested and approved on
20A (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, please refer a
minimum value of 10A B- or 8A C- characteristic breaker.
All parameters are specified at 25°C ambient and AC input unless otherwise indicated.
