Current limiting protects the circuit, and the ripple figure tells the rest · review
Kiprim DC310S programmable supply, 0 to 30 V, 0 to 10 A review
A programmable 0–30 V, 0–10 A bench supply controlled from a computer over USB, with four memory presets, user-set overvoltage and overcurrent limits, and a 2.8-inch screen that shows readings as numbers or curves.
The bottom line The one programmable supply in the family, with settable protection limits, memory presets and a curve display. Its figures for display steps and noise are missing, and its charging port is modest.
The DC310S listing, bullet by bullet
Five bullets: M1–M4 keys storing four preset voltages or currents; a 200–240 V input and overvoltage and overcurrent protection with user-set thresholds; a 2.8-inch TFT showing measurements as numbers or as a curve; a 5 V 1 A USB charging port, not for iOS devices, and a USB interface used for firmware updates and host-computer control, with instructions on a CD; and a box with the supply, power cable, manual, fuse, alligator lead and CD, plus a download link for the software.
Programmable, over one USB port
Computer control is what the title means by programmable. A test sequence — ramp a voltage, hold a current, log the result — can run without a hand on the knobs. The listing gives the interface and the software source, not the commands.
Limits the Kiprim user sets
No other supply here describes user-set protection thresholds. The DC310S lets the user choose the voltage and current at which it trips, which protects a specific load rather than the supply alone.
Readings as a curve
Plotting output over time on the screen shows how a battery’s charge current tapers or a motor’s draw spikes. It is the display feature no other supply in the family describes.
Availability
At the last look-up, the German, French, Italian and Spanish Amazon stores were asking 110 € to 115 €.
It is sold in the American and British Amazon stores as well, in their own currency, which the euro figures above leave out on purpose.

Where it earns its place, and where it falls short
Strengths
The only supply of the seven described as computer-controlled over USB
OVP and OCP thresholds set by the user
Four memory presets and a display that can plot readings as a curve
Compromises
A 200–240 V input only
The USB charging port gives 5 V 1 A and is said not to support iOS devices
No display resolution, ripple figure or design type

Questions makers ask before buying
Can the Kiprim DC310S be controlled from a computer?
Yes. The fourth bullet says the USB interface is the control interface for a host computer and the CD includes instructions for computer control.
Can the DC310S limits be set?
The second bullet says the user can set the overvoltage and overcurrent values independently, to protect the load.
