Matrix MPS-302 20V 10A 200W linear DC power supply

Matrix MPS-302 20V 10A bench supply

The Matrix MPS-302 is a single-channel linear DC power supply rated for 20V and 10A with a maximum output of 200W. It targets engineers, technicians and students who need precise, low-noise power for bench testing, electronic repair or automated integration work. The 3.5-inch TFT colour display shows voltage, current and power with 1mV and 0.1mA resolution. Adjustments can be made via numeric keypad or rotary knobs for quick manual control.

Replaces noisy switching units

Switching supplies often introduce ripple that masks small signals or distorts sensitive measurements; the linear topology here keeps output clean for production-line checks and lab routines. The upgrade is worth it when test plans demand fast voltage transitions under 10ms, programmable ramp rates or battery-charge profiles that switching designs cannot reproduce accurately. SCPI and MODBUS over RS-232, RS-485 and USB let the unit slot into existing automated test scripts without rewrite.

Linear regulation limits

Linear regulation dissipates the difference between input and output as heat, so continuous full-load operation runs the internal fan harder and warms the bench. The 110V/220V auto-switching input works worldwide, but the 13-pound chassis and 4.3 x 11.4 x 7.2-inch footprint need dedicated bench space. Users who need higher voltage, higher current or multi-channel output must look beyond this single 200W channel.
