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.
Clean, controllable power for serious bench work
The RZV 1000W bench power supply is built for the jobs where stability matters: powering prototypes, testing LED drivers, running DC motors with sensible limits, and fault-finding boards without risking further damage. The clear display and encoder-style adjustment help you set voltage and current quickly, then fine-tune with confidence.
Stable CV/CC behaviour you can rely on
Whether you鈥檙e setting a gentle current limit for first power-up or holding a fixed voltage for long tests, the RZV keeps control predictable. Constant Voltage (CV) and Constant Current (CC) modes behave consistently, making it easier to repeat results across sessions鈥攑articularly useful in education and small R&D environments.
Safety-first protections built in
With OVP (over-voltage), OCP (over-current) and OTP (over-temperature) protection, the supply is designed to help reduce common bench risks. For best practice, we recommend using correctly rated leads, keeping good ventilation, and ensuring proper earthing on a UK mains outlet.
UK ownership experience: fast delivery, VAT invoice, real support
Shipped from UK stock with a VAT invoice included, this is an easy buy for home users and organisations alike. If you鈥檙e choosing between ranges (for example 100V/10A vs 60V/20A), our support team can help match the supply to your real-world loads and cabling.

Stable CV/CC + Encoder Control
Smooth adjustment and dependable current limiting for repeatable testing
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.
Trusted on UK benches for clean, stable power
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.
Sarah Mitchell, London
Using it for LED driver testing and it holds CC mode nicely. Delivery was quick and it arrived well packed from UK stock.
Gareth Hughes, Cardiff
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.
Dr. Ailsa MacRae, Edinburgh
Plenty of power for 24鈥?0V projects and the display is easy to read. The fan is audible at high load, but that鈥檚 expected for 1000W.
Imran Qureshi, Birmingham
Compared to an Amazon special I tried previously, this feels more stable when current limiting. No more sudden jumps when I鈥檓 dialling in a small change.
Oliver Bennett, Bristol
Great for powering a range of modules on the bench. I鈥檇 have liked longer included leads, but with decent banana cables it鈥檚 spot on.
Cerys Williams, Swansea
Frequently Asked Questions
Ruziza Varia was set up for the people who actually use bench power supplies day in, day out鈥攅lectronics 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鈥攕table 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鈥檙e not sure whether you need 100V/10A or 60V/20A, we鈥檒l 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鈥檛 disappear after checkout. From first power-up to everyday use, we鈥檙e here to make your bench safer and your results more consistent.
