Inter-Tel 550.0131 9 AMP Power Supply for Axxess Systems - Refurbished

Inter-Tel 550.0131 9 amp power supply
Price: $135.00
Item Number: 550.0131-R
Manufacturer: INTER-TEL
Manufacturer Part No: 550.0131

Inter-Tel 550.0131 9 AMP Power Supply for the AXXESS system. With 1 year warranty.

The 550.0131 seems to be the replacement for the 550.0110 power supply. Although we've repaired many of the 550.0110 power supplies over the years we've never really seen a reason why a replacement should be needed. Both the 550.0110 and the 550.0131 seem to operate identically and be very reliable.

Testing the 550.0131 with a voltmeter:

A blinking light represents an overly high voltage

A solid light means there is voltage present not that the voltage is correct

The voltage may be checked by measuring between the ground and the voltage test point. Tolerances are + or - 5%.

The 550.0131 should power up with all green lights even when it is not plugged into the cabinet.
