Why Choose BenchPSU
The Ultimate DC Bench Power Supply for Your Workshop
Elevate your electronics diagnostics, repair, and prototyping with the BenchPSU Pro 3010D. Designed specifically for the modern UK workshop, this compact switching DC bench power supply delivers a highly stable, regulated output from 0 to 30 Volts and 0 to 10 Amps. Whether you are testing sensitive PCBs, charging lithium batteries, or powering automotive components, the Pro 3010D ensures you have clean, reliable power exactly when you need it.
Unrivalled Precision and Control
Unlike basic hobbyist units that rely on single-turn potentiometers, our adjustable bench power supply features independent coarse and fine adjustment knobs for both voltage and current. Paired with a bright, high-contrast 4-digit LED display offering 0.01V and 0.001A resolution, you can dial in your exact requirements with absolute confidence. The unit automatically transitions between Constant Voltage (CV) and Constant Current (CC) modes, protecting your delicate circuits from over-current damage.
Built for the Modern Technician
We understand that bench space is at a premium. The compact switching architecture reduces weight and footprint without sacrificing performance. As an added convenience, we have integrated a dedicated 5V/2A USB port directly onto the front panel-perfect for powering microcontrollers, testing mobile devices, or charging your phone without taking up an extra mains socket. Fully CE and UKCA certified, and supplied with a fused UK mains plug, the BenchPSU Pro 3010D is the dependable workhorse your lab deserves.

Customer Reviews
A massive upgrade for my repair bench. The 4-digit LED accuracy is brilliant compared to my old Jesverty unit. The coarse and fine tuning makes setting 3.3V for logic boards an absolute breeze.
Perfect electronics lab power supply. Arrived next day with a proper UK plug. The constant current mode kicks in flawlessly when testing shorted components.
We purchased several of these for our school lab. They are robust, easy for the students to use, and the CV/CC regulation is remarkably stable for a unit at this price point.
A very capable 0-30V 10A power supply. It handles electroplating tasks well, though the cooling fan does get a bit loud when you push it past 8 Amps for extended periods. Still, great value.
The built-in USB port is super handy for charging phones while I'm repairing them. Much better build quality than the Eventek model I had previously. Highly recommended for any UK technician.
Nice compact switching DC power supply. It doesn't take up much room on the desk and the coarse/fine knobs are great for dialling in exact voltages for custom LED arrays.
Fantastic value variable DC power supply for DIY electronics. The display is bright and easy to read from across the workshop, and the build quality feels very solid.
