The PeakTech 1094 two-pole voltage tester is a reliable and practical tool for measuring voltages up to 400 V. It uses LED indicators to display voltage levels at 12 V, 24 V, 50 V, 120 V, 240 V, and 400 V. The device supports both AC and DC voltage measurements and automatically detects and displays polarity when measuring DC voltages – no manual switching between AC and DC is required.
This tester operates without batteries, ensuring it is always ready for use, even after extended periods of inactivity. With its IP54 protection rating, the PeakTech 1094 is robust and resistant to dust and splashing water, making it suitable for use in both indoor and outdoor environments.

More than 200 power supply designs for home construction This USB Stick contains over 200 different power supply circuits from the volumes 2001-2022 of Elektor. The article search feature allows you to search full-text content. The results are always displayed as pre-formatted PDF documents. Highlights Cuk Converter Automatic Battery Switchover Battery Voltage LED Digital Benchtop Power Supply Lithium-Ion Charger Solar Cell Charger Electronic Fuse High Voltage Regulator Power Supply for USB Devices Step-up Converter for LEDs Battery Management and much more... On the Stick you will also find a folder with additional material such as PCB layouts, Gerber files and software.
Whatever the methods or even then financial means you have to make your circuits work, the power supply should rank high if not Number One in your considerations. The design block simply called “power supply” is hugely underrated both in electronics creation and repair. Yet, the “PSU” has enormous diversity and comes in wildly differing guises like AC/DC, generator, battery (rechargeable or not), PV panel, benchtop, linear or switch-mode, to mention but a few. The output ranges are also staggering like nano-amps to kiloamps and the same for voltages.This special covers the features and design aspects of power supplies.ContentsBasics
