The Ph-Pro can use any 5amp power supply that is rated for up to 16V AC or 28V DC output. We do not sell an internationally compatible supply for this particular system.
The PB105 is being phased out and will not be produced after 7/1/15 due new restrictions on AC power supplies.
The PB5 replaces the PB105.
The DB5 is the same as the PB5 but in a different form factor case that matches the SB5.
After 7/1/15 All systems will have power supplies that have output of 13.8v or 12v DC only.
