Current limiting protects the circuit, and the ripple figure tells the rest · review
NANKADF WPS-10H, 0 to 30 V, 0 to 5 A review
A 0–30 V, 0–5 A bench supply with a four-digit display showing voltage, current and power, automatic CC/CV switching, an output button and a short-circuit alarm, plus an 18 W USB charging port.
The bottom line A well-protected small supply with a clear display and a useful output button. At 5 A it suits electronics rather than motors, and the British cable in its box list is worth checking on delivery.
The WPS-10H listing, bullet by bullet
Five bullets: a four-digit LED display with 0.01 V and 0.001 A, three windows for voltage, current and power, 0–30 V and 0–5 A, 1.1 kg and 19 × 9 × 15 cm; encoder adjustment and an OUTPUT button that also clears an OCP trip; an 18 W USB fast-charging port; automatic CC/CV switching with OVP, OCP, SCP and temperature-controlled cooling; and a short-circuit alarm toggled by holding the CURRENT knob, with a box of supply, British power cable, crocodile-clip lead and German manual.
An output button on the NANKADF front panel
Switching the output without switching the supply. Settings can be changed with the load connected but unpowered, then applied with one press. The same button resets the supply after an overcurrent trip.
Protections named one by one
OVP, OCP and SCP are all listed, and the short-circuit alarm is described down to how it is enabled. That detail is what separates a stated protection from a claimed one.
0.001 A as a display step
A thousandth of an amp is what the display resolves. The listing does not state output accuracy, so the figure describes readability rather than precision.
Availability
At the last look-up, the German, French, Italian and Spanish Amazon stores were asking 48 € to 60 €.
It is sold in the British Amazon store as well, in its own currency, which the euro figures above leave out on purpose.
The American Amazon store returned no entry, so the buy button there opens a search rather than a missing page.

Questions makers ask before buying
How is the NANKADF short-circuit alarm switched on?
The fifth bullet says holding the CURRENT knob for 3 seconds turns the short-circuit alarm on or off. When enabled, the output stops and an alarm sounds on a short circuit or overcurrent.
What does CC/CV switching mean on the WPS-10H?
The fourth bullet says constant-voltage and constant-current values are preset by knob, and the supply switches between the two modes automatically according to the load.
