Product Description
The MPS-200 high precision programmable DC power supply is developed for laboratory and industrial precision power testing scenarios, focusing on stable low-noise output, rich programmable test functions and convenient remote automatic control, all technical indicators fully comply with the official datasheet parameters without virtual performance. This series offers diversified voltage-current specifications to match different test demands: MPS-200 (32V/6A/192W), MPS-201 (32V/10A/320W), MPS-202 (60V/5A/300W), MPS-203 (150V/2A/300W). The whole machine supports AC 110V/220V wide-range input with ±10% tolerance, adapting to global power supply environments. In terms of output precision and stability, the voltage setting resolution reaches 1mV and current resolution 0.1mA, with identical high readback resolution for accurate real-time value viewing. Under 25℃±5℃ standard environment, voltage setting accuracy ≤0.1%+8mV and current setting accuracy ≤0.2%+2mA; both load regulation and line regulation are controlled within ≤0.02% plus offset voltage/current value. The ripple noise is strictly suppressed: voltage ripple below 8~10mVrms and current ripple below 3~5mArms, effectively eliminating signal interference for precision circuit testing. For panel operation, five LED digital tubes simultaneously display real-time voltage, current and power values. Users can input parameters via numeric keyboard or quickly adjust values through the encoder knob with anti-misadjustment protection design. The machine supports saving and recalling up to 9 groups of commonly used test parameters, and the List output function enables automatic sequential testing with maximum 10 configurable steps, greatly improving efficiency for cycle aging and multi-condition verification tests. Comprehensive safety protection modules including over-voltage protection (OVP), over-current protection (OCP) and over-temperature protection (OTP) are integrated to cut off output automatically when abnormal status occurs and avoid damage to the power supply and tested DUTs. For automatic test system integration, standard RS232, RS485 and USB communication interfaces are equipped, fully compatible with SCPI and MODBUS communication protocols, supporting upper computer remote setting, data reading and program-controlled test. Optional LAN interface can be factory-installed for network centralized control. The intelligent cooling fan adjusts rotation speed according to internal temperature, reducing running noise under light load; the compact metal cabinet size is 111mm×170mm×250mm with net weight only 2kg, saving valuable bench space for laboratories and production lines. The operating environment is stable at 0~40℃ and relative humidity ≤80% non-condensing; storage temperature ranges from -15℃ to 70℃ with the same humidity limit. Standard accessories include power cable, test leads, RS232/RS485/USB cables and user manual; optional LAN communication interface is available for customized automation projects. Matrix provides complete SCPI and Modbus programming manuals for secondary development, and all MPS-200 series units enjoy a 3-year official warranty.
