Adjustable 30V 5A Bench Supply

The FNIRSI DPS-150 is a programmable DC power supply delivering up to 30 volts and 5 amps with a 150 watt limit. It offers 0.01 V and 0.001 A resolution on a 2.8 inch IPS display that rotates 90 degrees for flexible viewing. Ripple stays below 20 mV to protect sensitive circuits. USB-C PD and QC input modes are supported alongside a DC jack, though no adapter is included.

Hobbyists and repair techs needing precise

Engineers who require PC-driven test sequences will appreciate the six preset slots and PC programmability. The unit suits bench prototyping, battery charging with an external protection diode, and component validation. Buyers needing more than 5 amps or voltages above 30 volts should consider higher-rated supplies. It is not a high-power laboratory mainframe.

150 W headroom for typical 12 V and 5 V rails

At 12 volts the supply can provide its full 5 amp rating, giving 60 watts of clean power for microcontroller boards, sensor arrays or small motors. Pushing toward 30 volts reduces available current proportionally, so loads near 150 watts only occur at the top of the voltage range. The 20 mV ripple spec holds across the operating envelope, but sustained maximum output will trigger thermal protection.

Questions about this item

What power source must I provide to run the 150 W output of this DPS-150?

You need a separate USB-C PD or QC charger, or a DC source, capable of delivering at least 150 W; the unit ships without any power adapter.

Can I use my existing 4 mm banana leads and U-shaped terminals with the output connectors?

Yes, the supply provides 4 mm banana sockets, U-shaped terminals and fine-wire terminals so your current leads and lugs will fit directly.

How do I verify the ripple stays below 20 mV after I set the voltage and current?

Switch the 2.8-inch IPS display to curve mode; the on-screen waveform shows real-time output ripple so you can confirm it remains under 20 mV.
