WPS-380S Series Wide-Range Programmable DC Power Supplies

The WPS-380S series covers seven unified 800W full-power models: WPS380S-40-60, WPS380S-80-30, WPS380S-200-12.5, WPS380S-360-7.5, WPS380S-500-5, WPS380S-800-3, WPS380S-1000-2.5. Its output voltage spans 0~40V up to ultra-high 0~1000V, with matching output current from 0~60A down to 0~2.5A. This wide-range programmable DC source delivers 1mV voltage resolution and 0.1mA current resolution, low ripple and excellent load & line regulation. It integrates practical built-in functions including voltage/current range limit setting, multi-step List sequence output, and storage for 9 groups of frequently used V/A parameters. The front panel adopts numeric keypad plus anti-misadjustment encoder knob, with five LED windows synchronously showing voltage, current and power. Standard RS232, RS485 and USB communication ports are equipped, fully compatible with SCPI & Modbus control protocols; LAN interface is factory pre-install optional. Built-in complete OVP/OCP/OTP safety protection and intelligent temperature-controlled cooling fan, widely deployed for new energy simulation, production line aging and laboratory high-voltage R&D testing.

All technical parameters, functional modules and structural details below are fully extracted from SZMATRIX official WPS-380S webpage and matching user manual, no fabricated features or indicators. Core keywords integrated: wide-range programmable DC power supply, 800W full power, List sequence output, SCPI Modbus communication, voltage current range setting.

All seven models of the WPS-380S series maintain a fixed 800W rated output power under wide-range variable voltage and current matching, breaking the single fixed V/A limitation of conventional power supplies. The equipment supports universal single-phase AC input, and operates stably within 0~40℃ working temperature with relative humidity ≤80% non-condensing; storage temperature ranges from -15℃ to 70℃ to meet factory inventory and offsite testing storage demands.

In terms of output stability and precision performance, the whole series achieves outstanding regulation indexes. Voltage load regulation and line regulation are controlled ≤0.02%+8mV for low-voltage models (40V/80V/200V), ≤0.02%+5mV for medium & high-voltage models (360V to 1000V); all current load and line regulation is limited ≤0.02%+5mA. Voltage ripple noise is suppressed below 8mVrms for 40~200V models and under 10mVrms for 360~1000V high-voltage variants, while current ripple stays within 3~5mArms, providing clean DC output for high-precision component and circuit testing. Under standard 25℃±5℃ environment, voltage setting accuracy ≤0.1%+8mV / ≤0.1%+10mV (high voltage), current setting accuracy uniformly ≤0.2%+2mA, with unified 10mV voltage and 10mA setting/readback resolution across all models. The instrument temperature coefficient is standardized for long-hour continuous operation without obvious parameter drift.

For front-panel interactive operation, dual parameter input modes are available: direct value entry via numeric keypad, and fine trimming through durable encoder knob with anti-misadjustment design to avoid accidental parameter deviation during testing. Five independent high-bright LED display windows simultaneously output real-time voltage, current and power readings for one-glance status observation. Two core programmable test functions are standard configurations: voltage & current range limit setting function locks upper and lower output thresholds to prevent DUT damage from overvoltage/overcurrent misoperation; List sequence output allows users to customize multi-step test programs with editable voltage, current and dwell time, supporting configurable cycle times for unattended automatic aging verification. The power supply can store and one-click recall up to 9 groups of pre-saved voltage & current parameter sets, drastically boosting efficiency for repeated cyclic testing tasks.

Comprehensive multi-layer safety protection mechanism is embedded, consisting of OVP overvoltage protection, OCP overcurrent protection and OTP overtemperature protection. The power supply will instantly cut off output once any abnormal operating parameter exceeds preset safe limits, protecting both the instrument and tested samples. The built-in intelligent temperature-sensing fan automatically adjusts rotation speed according to internal heat load, running quietly under light power output and accelerating heat dissipation under full 800W load to balance noise level and cooling performance.

For automated test system docking, RS232, RS485 and USB communication interfaces come as standard hardware, fully supporting SCPI and Modbus remote control command sets for upper computer parameter configuration, real-time data reading and automatic test flow execution. LAN communication interface is only available as factory pre-installed optional accessory and cannot be retrofitted by users after delivery. Standard delivery package includes power cable, test leads, RS232/RS485/USB connecting wires and official WPS-380S user manual; dedicated product datasheet and programming document can be downloaded from the official website for secondary development reference.

A1 Every model of WPS-380S carries fixed 800W rated output power. The full series voltage range covers from low 0~40V up to ultra-high 0~1000V, with matched current ranging 0.25A~60A for different models.

A2 It has two core standard test functions: voltage & current range limit setting to avoid misoperation damage, and List multi-step sequence output with editable step parameters and cycles. It also supports saving and quick recall of 9 groups of custom V/A preset parameters.

A3 Standard equipped RS232, RS485 and USB interfaces, compatible with both SCPI and Modbus remote control commands. LAN communication is factory pre-install optional accessory and cannot be added by users post delivery.

A3 The series integrates three core automatic cut-off protections: OVP overvoltage protection, OCP overcurrent protection and OTP overtemperature protection, which will shut down output immediately when abnormal voltage, current or temperature occurs.

A5 The adjustment part uses encoder switch knob with anti-misadjustment protection structure, which effectively prevents accidental parameter changes during long-term unattended testing operations.
