4-Channel 30V Linear Supply

The Matrix MPS-3034A is a four-channel programmable linear DC power supply. Each channel delivers zero to thirty volts at up to three amps with independent voltage and current adjustment. It suits laboratory bench work, automated test sequences and development tasks that require clean, low-ripple outputs.

Check bench space and RS-232 access

The unit measures seventeen point three inches wide, thirteen point four inches deep and three point five inches high, weighing sixty-six pounds. Ensure the bench can support that footprint and weight. Verify the host computer or controller provides an RS-232 port or a compatible adapter for remote operation.

RS-232 and list output extend control

The built-in RS-232 interface enables computer-driven voltage and current changes plus the list output function for automated step sequences. Nine preset stores and sequence programming reduce manual reconfiguration. OVP and OCP safeguards protect connected loads during remote runs.

Questions about this item

Does the Matrix MPS-3034A ship with all four channels ready to use or do I need extra leads?

The package includes the 4-channel linear supply itself; the listed contents show the unit only, so test leads or rack-mount brackets must be sourced separately.

How do I decide between using the 30 V 3 A channels independently or linking them for higher output?

Each channel adjusts voltage and current independently at 1 mV and 0.1 mA resolution; press the series/parallel key to combine channels when a single higher-voltage or higher-current rail is needed.

What does the 1 mV/0.1 mA resolution mean when the supply is driving a real load?

It means the front panel or RS-232 interface can set voltage in 1 mV steps and current in 0.1 mA steps, giving fine control for low-level circuit testing across all four channels.
