Single-channel bench supply

The OWON SP3051 is a single-channel linear DC power supply designed for bench use. It delivers adjustable output from 0 to 30 volts and 0 to 5 amps with a maximum power of 150 watts. Engineers, technicians and hobbyists can use it for circuit prototyping, component testing and general lab work.

Installation and common issues

The unit connects to mains AC and provides DC output through front-panel terminals. A 3.7 inch TFT LCD shows voltage and current readings with a resolution of 10mV and 10mA. Low ripple and noise performance supports sensitive analogue circuits. Over-voltage and over-current protection help prevent damage during accidental shorts or misconfiguration.

Pre-purchase checks

Verify that your application fits within the 30 volt and 5 amp limits of the single output channel. Confirm that RS232 connectivity with SCPI command support meets your automation or remote-control requirements. The supply operates in both constant-voltage and constant-current modes, so ensure these modes suit your test procedures.

Questions about this item

How can I confirm the SP3051 is regulating correctly after I connect a load?

Set a voltage and current limit, enable the output, then watch the 3.7 inch TFT LCD; the readout should stay within the 10 mV / 10 mA resolution while the CV or CC indicator matches the load condition.

What comes in the box with the SP3051 and what must I source separately?

The unit includes the linear DC power supply with RS232 port and SCPI support; you will need to provide your own test leads and a DB-9 serial cable if you plan to control it remotely.

The SP3051 is a single-channel 30 V 5 A 150 W model — how do I decide if this capacity fits my bench needs?

Choose it when your circuits draw up to 5 A at 30 V and you want low ripple, over-voltage and over-current protection plus programmable memory in one compact bench supply.
