Power supply – auto switch over
features
• 5V/16A power supply
• Parallel power supply operation
• Auto switch over for fail save operation
• Power fail signal if only one of the two parallel PS is on line
• Front side LED power indicator
• Front side potentiometer to set the output voltage
operation
• Set the output voltage to +5V +/- 10mV if two C8903 are
operating in parallel
important information for dual operation
If the power fail signal is used for monitoring purposes it is extremely important to set the
output voltage within a range of +/- 10mV for both power supplies. If the total current is less
then 3,2A it may otherwise happen that one of the two power supplies will take over full load.
This is not a technical problem but it will activate the power fail signal!
If you need to exchange one of the parallel operating power supplies you must set the output voltage
of the remaining one to +5,00V (second one removed). Now you must insert the new one and
remove the other party temporarily (be sure the new one is operating properly). The new one must
now be set to +5,00V +/- 10mV. Now you can reinsert the other one for parallel operation. Both
modules will perform the load balancing automatically.
Junger Audio uses an OEM power supply module. For technical details please refer to the
documentation of the OEM.
