Product Description

The MPS-300 single-channel programmable DC power supply is developed for precision electronic testing, battery performance verification and automated industrial testing, all parameters and functions fully extracted from the official product specification without any fabricated performance. This series provides abundant model specifications to match diversified test requirements: MPS-301 (20V/6A/120W), MPS-302 (20V/10A/200W), MPS-303 (36V/3A/108W), MPS-304 (36V/6A/216W), MPS-305 (36V/10A/360W), MPS-306 (60V/3A/180W), MPS-307 (60V/6A/360W), MPS-308 (80V/2A/160W), MPS-309 (100V/1A/100W), MPS-310 (160V/1A/160W). The whole machine rise time is controlled within less than 10ms, and users can adjust the rise slope flexibly according to test standards.

In terms of precision and output stability, the voltage setting and readback resolution reaches 1mV, while current resolution is 0.1mA. Under standard 25℃±5℃ environment, voltage setting accuracy ≤0.1%+5mV and current setting accuracy ≤0.2%+1mA. Load regulation and line regulation are strictly controlled within 0.05%+offset value for voltage and 0.1%+3~5mA for current. The ripple noise is suppressed at low level: voltage ripple ranges from 5mVrms to 15mVrms depending on models, and current ripple is between 2mArms and 6mArms, effectively avoiding signal interference for precision circuit testing. The temperature coefficient of the whole unit is 300ppm, supporting stable operation in long-term continuous testing.

For human-machine operation, the front panel is equipped with a 3.5-inch high-visibility TFT screen, which clearly displays voltage, current, power, OVP, OCP and running status. Two operation modes are available: direct parameter input via numeric keypad and quick fine-tuning through the adjustment knob. The machine supports external USB drive connection to save and read test program files locally without computer assistance.

The product integrates rich professional test functions. The List sequence output function supports up to 99 configurable steps, allowing users to customize voltage, current and dwell time for each step. It provides three trigger modes: automatic trigger, button trigger and external trigger, with maximum cycle count up to 99999 for repeated aging and cycle testing. Exclusive battery charging function is embedded, which supports setting standard voltage, standard current, trickle voltage, trickle current and charging end current as well as charging duration; the power supply will automatically cut off charging output once the preset termination conditions are satisfied to prevent battery overcharge damage. Besides, users can switch and set CC/CV priority mode according to different test objects.

For automated system integration, standard communication ports including RS-232, RS-485 and USB are pre-installed, fully compatible with SCPI and Modbus remote control protocols. LAN interface is optional and can only be pre-installed at the factory before delivery. Standard accessories include RS-232 cable, RS-485 cable, SENSE cable and USB cable; complete user manual is provided for parameter configuration and programming operation guidance.

Each model has independent dimensions and net weight from 4.5kg to 7kg with metal casing for heat dissipation. The unit supports bench placement and rack installation, matching various laboratory and production station layouts. The product has dedicated user manual and datasheet downloadable from the official website for technical reference.
