Matrix MPS-309 100V 1A linear power supply

The Matrix MPS-309 is a single-channel linear programmable DC power supply rated at 100V 1A and 100W. It targets engineers and technicians who need clean, low-noise output for bench testing, production-line verification, laboratory research or automated equipment integration. The 3.5-inch TFT colour display and numeric keypad provide direct voltage and current adjustment. Built-in battery-charging and list-output functions extend its usefulness for routine test sequences.

Linear regulation limits and interface constraints

Linear topology keeps ripple and noise low but caps maximum output at 100W with 1mV voltage and 0.1mA current resolution. The unit accepts 110V or 220V input for global use. Remote voltage compensation improves accuracy at the load. Communication relies on RS-232, RS-485 and USB ports supporting SCPI and MODBUS commands; no Ethernet or GPIB option is included. Voltage rise time is under 10 ms and the upward slope is adjustable.

Installation notes and common pitfalls

The supply measures 4.3 x 11.4 x 7.2 inches and weighs 13 pounds, so bench space and a sturdy shelf are required. Intelligent fan control reduces noise but airflow clearance at the rear must be maintained. Users sometimes forget to enable remote sense when leads are long, causing voltage drop at the device under test. SCPI command syntax differs from MODBUS register mapping; mixing the two without consulting the manual leads to configuration errors.

Questions sur cet article

Should I choose the 100V 1A version or a different capacity for bench testing?

This model provides a single 100V 1A output rated at 100W, suitable for production line, lab and repair bench tasks that need precise linear regulation.

What does the 1mV and 0.1mA resolution mean when I set voltage or current on the bench?

You can adjust output in 1mV voltage steps and 0.1mA current steps, giving fine control for low-level circuit validation and battery charging profiles.

Which interfaces are built in and what do they limit in automated test setups?

RS-232, RS-485 and USB ports support SCPI and MODBUS commands, letting you script sequences and log data to an external USB drive.
