Descriptions

The MPD Series are multi-channel programmable linear DC power supplies, including models 3303-S, 3303-SA, and 4303-S. They support multiple independent outputs (e.g., CH1/CH2: 0~30V/0~3A; CH3/CH4: 2.5V/3.3V/5V or 0~10V), adapting to multi-device synchronous testing scenarios. A key highlight is their flexible output modes, supporting three operating modes: independent, series (max. 64V), and parallel (max. 6A) to meet diverse power requirements. Resolution reaches 1mV/0.1mA/1mW, with voltage ripple ≤3mVrms and load regulation ≤0.01%+3mV, ensuring stable and clean output. Operation is convenient with a 5-digit LED display and silicone keys with indicators, supporting 4 groups of parameter storage and recall; the knob can switch between coarse and fine adjustment (FINE mode). Equipped with over-voltage protection (OVP), over-current protection (OCP), and over-temperature protection, an intelligent temperature-controlled fan reduces noise. A standard USB communication interface, compatible with SCPI and MODBUS protocols, facilitates remote control. With dimensions of 210×130×265mm and a 3-year warranty, it is suitable for electronic R&D, automated testing, and other scenarios.
