The ABB PHARPS32000000 is a Harmony MPS III plug-in power supply tray providing 5 V DC at 60 A, +15 V DC at 3 A, -15 V DC at 3 A and 24 V DC at 17 A for system and field-power duties.
Confirm the required 5 V, +15 V, -15 V and 24 V loads against the installed rack and field circuits. A matching tray number does not authorize operation above any documented rail rating.
Verify the MPS III power-entry panel, breaker arrangement and the selected 120/240 V AC or 125 V DC input before inserting or energizing a replacement tray.
Where two identical trays are installed, verify both positions, load-sharing behavior, alarm status, fan operation and the ability of the remaining line to support the intended cabinet load.
Measure and document the loading on the 5 V, +15 V, -15 V and 24 V rails before replacement. Investigate an overloaded rail or failed downstream load rather than treating the tray as the only possible fault.
Confirm the PHARPSCH100000 chassis, compatible power-entry panel, fan assembly, bus monitor and system-power bus connections. A redundant pair should be tested one line at a time under controlled conditions.
