Stable CV/CC + Encoder Control
Smooth adjustment and dependable current limiting for repeatable testing
Carpentry Tools | Ruziza Varia
A UK-stocked 1000W variable DC bench power supply with precise encoder control, stable CV/CC operation and built-in protections for lab, repair and maker benches.
How to Use
- Place the power supply on a stable bench with at least 10 cm clearance around vents.
- With the output OFF, connect your load using correctly rated leads (recommended: 4 mm banana plugs to insulated clips where appropriate).
- Set a safe current limit first: select current adjustment and dial the limit down for initial power-up.
- Set the target voltage using the encoder control, then enable output.
- Observe CV/CC status and the V/A readings; adjust slowly until you reach the required operating point.
- After use, disable output, then disconnect the load. Allow the unit to cool before storing.
What Our Customers Say
The encoder control makes it far easier to set a precise current limit for first power-up on repaired boards. CV/CC switching is predictable, which is what I needed.
Using it for LED driver testing and it holds CC mode nicely. Delivery was quick and it arrived well packed from UK stock.
We use it for student lab work powering prototype circuits. The protection features and clear V/A readout make demonstrations safer and easier to follow.
Plenty of power for 24–60V projects and the display is easy to read. The fan is audible at high load, but that’s expected for 1000W.
Compared to an Amazon special I tried previously, this feels more stable when current limiting. No more sudden jumps when I’m dialling in a small change.
Great for powering a range of modules on the bench. I’d have liked longer included leads, but with decent banana cables it’s spot on.

Ruziza Varia was set up for the people who actually use bench power supplies day in, day out—electronics makers, repair techs, R&D teams and education labs across the UK. We saw too many listings that promised big numbers without explaining test conditions, protections or safe wiring.
Our approach is simple: proof over promises. We publish plain-English performance information and focus on the details that matter on a real bench—stable CV/CC behaviour, low ripple/noise, reliable protection circuits, and controls that let you dial in exactly what you want.
Everything we sell is UK-stocked for fast delivery, with straightforward returns and a proper VAT invoice for business and education customers. If you’re not sure whether you need 100V/10A or 60V/20A, we’ll help you choose the right model and the right leads for safe, repeatable results.
Ruziza Varia is built around long-term ownership: honest specs, practical guidance, and support that doesn’t disappear after checkout. From first power-up to everyday use, we’re here to make your bench safer and your results more consistent.
