TECHNICAL DATASHEET
CliQ M DIN Rail Power Supply
24V 81.6W 1 Phase / DRM-24V80W1PN
Advanced Power Boost (APB)
With multiple loads connected in a system and due to one of fault load a large outrush current is drawn (demanded), this will be
detected by APB. This APB will trip the circuit breaker (circuit breaker with appropriate rating base on the system load) on the current
path of faulty load due to high current. This thus prevents the system from shutting down while the other connected current paths
continue to operate without interruption.
The following waveforms demonstrate the typical output voltage and output current when APB is activated.

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 in instruction sheet with B or C characteristic breaker.
