TECHNICAL DATASHEET
CliQ M DIN Rail Power Supply
24V 120W 1 Phase / DRM-24V120W1PN
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 (IO Max), for a maximum duration of 7
seconds. If the power boost lasts longer than
maximum duration, the output current will limit to
6.5A typ. and VO (output voltage) will start to
droop, refer to the details in overload &
overcurrent protections and the next Power Boost
will be available after power boost recovery time
defined on Page 4. In order to avoid this, need to
maintain the duty cycle & recovery time to ensure
that average (R.M.S) output power shall not
exceed the continuous maximum, see duty cycle
calculation below.
