Toshiba RPSU280 power supply for DK280 and DK424 systems - refurbished

Item Number: RPSU280-R
Manufacturer: Toshiba
Manufacturer Part No: RPSU280A

Toshiba RPSU280A is the cabinet power supply for the DK280 DK424 base and expansion cabinets. All RPSU280 power supplies come with a one year warranty. The RPSU280 fits into the DKSUB280A, DKSUE280A, DKSUB424A, and DKSUE424A cabinets. It will not fit into the DK424i cabinets.(CHSU672)
These power supplies seem to have a life span of about 10 to 15 years before they need components replaced. This is one case where "fully tested" does not mean much. Nobody can tell you how long a 12 year old power supply that tests good will last. These power supplies need to have components replaced before they can be called reliable.
Under normal conditions only the base cabinet power supply has the base plug with the green loop wire. This gives the base cabinet power switch the ability to work. All the other expansion cabinets should be left with their power switches in the on position and be controlled by the main cabinet.
For troubleshooting purposes the green loop plug should be moved from power supply to power supply to determine which power supplies work and which don't. For example if you have a base and two expansion cabinets that are completely dead it is likely that the base RPSU280A is bad. Simply move the loop plug to the expansion cabinets and see if they will power up on their own. By moving a RPSU280A out of an expansion and into the main in this example you may be able to get two of the three cabinets back up in a couple of minutes. The RPSU280 should power up with all green lights even when not plugged into a cabinet provided that it has the green loop plug installed.
You may find that some or all of your DK424 cabinets have a RPSU424A power supply not a RPSU280A. This power supply was introduced later in the life of the DK424 and is interchangable with the RPSU280A. Although the green loop plug is different just to make life a little more challenging.
The RPSU280A had a very long and dependable life before they started failing. All replacement power supplies we ship have the components replaced that have been causing these units to fail. We have seen nothing to indicate that a refurbished power supply will not last another 10-15 years.
