Introduction: In Search of a Reliable Power Supply
If you’ve ever worked on electronics development, repairs, or simply enjoyed building circuits at home, you know how valuable a stable and accurate power supply is. The PeakTech P 6070, part of the brand’s lineup of linear regulated lab power supplies, landed on our test bench. The question was: is it worth the price, what can it really do, and who is it for?
First Impressions: Sturdy, Compact, Professional
Out of the box, the PeakTech 6070 gives off a great first impression. The metal case feels solid and durable yet surprisingly compact. The front panel is clearly laid out, and the large LED displays are easy to read even in a well-lit workshop.
In the box:
-
Power supply unit
-
Power cord
-
USB-A to USB-B cable
-
User manual and software CD
In Use: Accurate, Quiet, Logical
1. Setup and Control
Startup is immediate, and the large digital readouts are stable and precise. Voltage and current can be set using rotary encoders, and we appreciated the fine 0.1 V / 0.1 A resolution, making it perfect for hobby and professional use alike.
2. Silent Passive Cooling
One of the standout features during our tests was completely silent operation. There’s no fan, no humming—just total silence. Even under extended load, the unit remained cool to the touch thanks to its passive heat dissipation.
3. Load Test: Stability Above All
We tested several load types:
-
LED strip (12 V, 1.5 A)
-
Active speaker (15 V, 2 A)
-
DIY amplifier (24 V, 3.2 A)
-
Voltage sweep on a motor controller
In all cases, voltage stayed rock solid, with zero visible ripple or fluctuation. The displays accurately reflected changes, and the unit handled dynamic loads without hiccups.
USB Control and Software: Minimal but Functional
The included Windows-only software is basic, but does the job. You can remotely control the power supply via USB, and even log data over time (voltage/current vs time) – a major bonus for automated testing.
Safety Features: Effective With Slight Delay
The PeakTech P 6070 includes:
-
OVP – Overvoltage protection
-
OCP – Overcurrent protection
-
SCP – Short-circuit protection
-
OTP – Overtemperature protection
-
BOP – Brown-out protection
We intentionally triggered a short circuit, and the unit cut power in about 0.2 seconds – acceptable for most use cases, though those needing ultra-fast cutoffs should take note.
Who Is It For?
Hobbyists
Perfect for Arduino projects, RC builds, or breadboarding.
Educational Use
Simple interface and robust protection make it ideal for lab environments and classrooms.
Service Technicians
With its ability to handle sudden load changes, it’s a strong choice for electronics repair work.
Drawbacks We Found
-
Static LED display – doesn’t change color or flash to indicate active state.
-
Passive cooling only – avoid placing it in confined, hot enclosures.
-
Software is Windows-only – no native macOS/Linux support out of the box.
Summary: A Solid Lab Companion
The PeakTech P 6070 won’t revolutionize lab power supply design, but it performs its role flawlessly. Accurate, quiet, safe, and simple to use—at a reasonable price for its feature set.
