Our Balance 580 has been a solid performer for number of years. Yesterday, the power supply unit (FSP100-50LGA) failed probably from power surges. I have been trying to get a replacement power supply unit from http://www.fspgroupusa.com but do not see exact model on their site. Besides, the cable connectors for those units are also different from those of the Peplink power supply unit. Would appreciate if a kind soul point me to a place where I can order the unit online? I live in Bhutan (Asia) so it’s difficult to get it here.
