The MPS-4 Series are programmable linear DC power supplies, including models such as MPS-3054 and MPS-30104, suitable for production lines, laboratories, automated equipment integration testing, and other scenarios. A core highlight is the 4-in-1 design, which enables easy installation and space-saving. Each channel is independently adjustable and isolated from others, with high resolution of 1mV/0.1mA. It supports List sequence programming, and the linear power supply design ensures low ripple. In terms of performance, the rated output voltage of the 4 channels ranges from 0~30V to 0~60V, and the current ranges from 0~3A to 0~10A. The voltage load regulation is ≤0.02%+5mV, the current load regulation is ≤0.02%+5mA, and the ripple noise is ≤2mVrms (voltage) and 5mArms (current). It supports front and rear output ports, 9 groups of preset storage, and comes with a standard RS232 interface, providing efficient power for multi-device synchronous testing.
