Technical Information
PMC-24V300W1BA
 Dynamic Load
Additionally power supply is capable of dynamic change of load from 0% to 100% with o/p voltage
within +5% of regulation limits. See below the dynamic behavior of the PSU.
 Redundancy & Parallel Operation with Oring Diode
See below figure for a typical Redundant/Parallel operation of PSU using CliQ series power supplies.
The 2 power supplies PSU1 & PSU 2 are connected thru a twin diode where Anode1 A1 is connected
to the +Ve i.e. 24V of PSU1 and Anode2 A2 is connected to the +Ve i.e. 24V of PSU2 and the output
ground GND are shorted together.
The output of these 2 power supplies PSU1 & PSU2 is drawn from the Cathode K of the twin diode
thus making the power supply work in Redundant/Parallel operation.
Redundant Operation:
When 2 power supplies are connected in below manner the power supply PSU1 or PSU2 whichever
has higher output voltage takes the max load and the other PSU is operating in standby (@No Load)
in case of failure on PSU1, PSU2 takes over the load from PSU1 and supplies the required power to
end system.
