Matrix MPS-203 300W Programmable Supply

The Matrix MPS-203 is a new switching programmable DC power supply rated at 300W with a 150V and 2A output range. It delivers 1mV and 0.1mA resolution on a five-digit LED display that shows voltage, current and power simultaneously. Nine memory presets store voltage and current settings for quick recall, while a list output function enables sequenced operation. Interfaces include RS-232, RS-485 and USB with SCPI and MODBUS support for remote control.

Engineers and test technicians needing bench-top

This unit suits engineers, R&D staff and educators who require high-resolution programmable output with low ripple and multiple communication interfaces. The intelligent temperature-controlled fan and adjustable screen brightness support extended bench use. Buyers needing higher current capability or multiple independent channels should consider other equipment, as this model provides a single 2A output.

Check mains voltage and communication needs

Verify that your bench can accommodate the unit's 4.4 by 9.8 by 6.7 inch metal enclosure and that the available AC input matches the supply's requirements. Confirm whether your automation software uses SCPI or MODBUS over RS-232, RS-485 or USB. Ensure the 150V maximum output covers the test voltages required for your devices under test.

Questions about this item

Does the Matrix MPS-203 need a specific mains voltage to operate?

The supply accepts a wide AC input range so it works on standard bench power without a special circuit.

Can I control this unit from an older PC that only has a serial port?

Yes, the built-in RS-232 interface lets you send SCPI or MODBUS commands directly from legacy hardware.

How do I verify the 1mV and 0.1mA resolution is active after power-on?

The five-digit LED display shows voltage, current and power simultaneously; the smallest digits will change in 1mV and 0.1mA steps when you adjust the knobs.
