Why Choose DCPSU Lab
Precise power for testing, repair and development
This DC bench power supply is built for users who need stable, controllable output across a wide range of bench tasks. With adjustable 0-30V voltage and 0-10A current, it is ideal for powering circuits, fault-finding boards, testing modules and supporting electronics development work. The regulated DC output helps deliver dependable performance for hobby benches, professional repair counters and teaching laboratories alike.
Faster, finer control on the bench
Unlike basic low-cost alternatives, this unit uses encoder-based coarse and fine adjustment so you can dial in settings more quickly and accurately. The clear 4-digit display improves visibility when setting voltage and current, helping you work with greater confidence during sensitive testing. Constant voltage and constant current modes support a wide variety of electronics applications, from component checks to controlled power-up of projects.
Built with safety and modern convenience in mind
For day-to-day workshop use, practical safety matters just as much as raw output. This adjustable bench power supply includes over-current protection and short-circuit focused protection features to support safer operation during electronics repair and training use. Integrated USB-A and Type-C fast charging ports add extra utility on the bench, letting you power or charge compatible devices without reaching for a separate charger.
A stronger choice than generic bench PSUs
Compared with many generic units from brands such as WANPTEK POWER and KORAD, this model stands out with its blend of precision readout, fine encoder control and integrated fast-charge convenience. It is a feature-rich laboratory DC power supply for buyers who want more than a basic bench PSU, while still keeping to a sensible mid-range budget.

Customer Reviews
I bought this for electronics repair at home and the 4-digit display is far easier to read than my old bench PSU. The current limiting works properly and the USB-C port is surprisingly handy for keeping my phone charged while I work.
Arrived quickly from the UK and was well packed. The encoder coarse and fine adjustment is much better than the cheaper knob-only supply I had before, especially when setting low voltages for board testing.
We use this as a teaching lab power supply for undergraduate electronics exercises. The regulated output is stable, the display is clear from across the bench and the protection features make it suitable for supervised student work.
Very capable 30V 10A bench power supply and excellent value for the specification. My only minor criticism is that the fan becomes noticeable when drawing higher current, but performance has been solid.
I was comparing this with WANPTEK POWER and KORAD options and chose this because of the USB-A and Type-C outputs plus the finer encoder control. For my repair bench it feels like the more practical everyday choice.
Using it as a DC power supply for electronics projects and battery-related bench testing. Voltage and current settings are easy to dial in, though I would have liked slightly longer included leads. The supply itself is excellent.
Brilliant adjustable DC power supply for hobby builds and fault-finding. It gives me bench-grade control without spending a fortune, and the Type-C fast charging is a small feature that makes a big difference on a busy desk.
