Five isolated channels in one unit

The Matrix MPS-3055 combines five independent 30V 5A linear channels in a single 19-inch rack enclosure. Each channel is electrically isolated and can be operated in series or parallel with a single key press. Engineers and test labs use it when multiple precise rails are required without cross-talk.

Linear topology keeps ripple and noise low

Linear regulation delivers low output ripple and minimal audible noise during bench use. The intelligent fan system adjusts speed based on internal temperature, so airflow increases only when thermal load demands it. Power draw scales with the programmed output across the five channels.

Nine storage groups and RS232 simplify repeat tests

Nine memory groups let operators recall voltage and current presets instantly from the front panel. RS232 provides scripted control for automated sequences. The package includes the supply unit only; rack-mount hardware and control cables are not supplied.

Questions about this item

How do I install the Matrix MPS-3055 in a 19 in rack and what step is often missed?

Mount the unit using its 19 in rack width and 14.6 in depth, then secure all four rear brackets; the step often missed is verifying each of the five isolated channels for correct polarity before powering on.

What maintenance will the Matrix MPS-3055 need over time?

Clean the intelligent fan system intake regularly to maintain airflow; the linear supply design has no user-replaceable filters, so dust removal is the only routine task.

What limit appears first when running all five channels at 30 V and 5 A continuously?

Internal heat buildup triggers the intelligent fan system to ramp up before any electrical limit is reached.
