Programmable DC bench supply

The Matrix WPS300S-80-10 is a wide-range programmable DC power supply delivering 0-80V and 0-10A at up to 300W. It provides 1mV and 0.1mA setting resolution with ripple below 8mVrms and 5mArms. Standard interfaces include RS232, RS485, and USB supporting SCPI and MODBUS commands. The unit weighs 4.4lb and measures 4.4in by 9.9in by 6.7in.

Engineers needing programmable DC power

This supply suits test engineers, repair technicians, and hobbyists who require adjustable voltage and current with remote control via serial or USB. The LIST output function supports up to 9999 cycles for automated test sequences. Users needing more than 80V or 10A from a single channel should consider a higher-rated model. Applications requiring linear-regulation topology are not addressed by this switching design.

300W at 80V 10A output

The decisive specification is the 300W maximum power delivered across a 0-80V and 0-10A range. This single figure defines whether the unit can drive your specific load. The supply accepts AC 110V or 220V input with ±10% tolerance. A five-digit LED display offers six brightness levels and the buzzer can be disabled. Nine storage groups save instrument settings for quick recall.

商品問答

What clearance does the 4.4 in x 9.9 in x 6.7 in bench unit need on a workbench?

Allow at least the 4.4 in height, 9.9 in width and 6.7 in depth plus a few centimetres around the sides and rear for airflow and cable bend radius.

How do I connect the RS232, RS485 and USB interfaces, and what step is often missed?

Plug the USB cable into a PC port, wire RS232 or RS485 to the matching controller, install the SCPI or MODBUS driver, then select the correct COM port in software — the step often missed is setting the baud rate to match the supply.

When should the internal fan or output terminals be inspected on a 300W programmable supply?

Check the fan for dust buildup every six months and verify the output binding posts are tight after any move; no user-replaceable parts are specified, so contact service if noise or regulation drifts.
