WPS-300S Series Wide Range Programmable DC Power Supply

The WPS-300S Series wide-range programmable DC power supplies include models like WPS300S-80-6 and WPS300S-30-20, with voltage from 0-30V to 0-150V and current from 0-5A to 0-20A, meeting multi-power testing needs. Core advantages include high resolution (1mV/0.1mA) and low ripple (≤10mVrms), with load regulation ≤0.02%+8mV ensuring precise and stable output. Five LED displays show real-time voltage, current, and power, supporting quick parameter setting via a numeric keypad or knob; 9-group data storage enhances operational efficiency. The knob uses an encoder switch for quick use and anti-misadjustment protection. Supporting List sequence testing (up to 10 cycles), over-voltage/over-current/over-temperature protection ensures comprehensive safety. Optional RS-232/USB/RS-485 interfaces compatible with SCPI facilitate system integration. Compact (111×170×250mm) and lightweight (2kg) with an intelligent fan for temperature control, the series comes with a 3-year warranty, suitable for industrial testing and laboratory R&D.

FAQ

What is the recommended way to deploy the unit in a testing or production bench?
The device should be installed on a stable work bench or integrated into a rack-based automation system. Connect the AC input, configure the output parameters (voltage/current) via front panel or remote interface, then enable protections before applying load. This setup ensures you are utilising the unit as a reliable dc power supply.

What warranty and ongoing support does the manufacturer provide?
Matrix offers warranty coverage for manufacturing defects and calibration drift for a defined period from shipment. Post-warranty support includes access to firmware updates, technical consultancy and spare-parts management. This service model supports clients using the product as a programmable dc power supply in long-term programmes.

Is the unit compatible with other measurement or control equipment in an integrated test cell?
Yes. The unit features standard communication (USB/RS-232/RS-485) and supports programmable sequences. It can be used as an adjustable dc power supply in systems that also include electronic loads, oscilloscopes or automation controllers.

What is the typical lead time for bulk orders or OEM supply agreements?
Lead time depends on configuration and quantity; for standard models we maintain production readiness to service wholesale power supply demands. Clients are advised to project their schedule at least several weeks ahead so we can allocate manufacturing capacity and ensure timely delivery.

How are data-security and operational safety handled when using remote control or network-connected test setups?
The unit runs command-based control; it does not store user personal data. Operational safeguards include over-voltage, over-current and temperature protection. When used as a 12 volt dc power supply within automated test flows, proper interface isolation and secure network design are recommended to maintain safe overall system behaviour.
