6 lip 2024 · When your power supply dies, it can mean that the fuse has been blown. Most fuses are soldered directly to the circuit board. Replacing them is a relatively straightforward process that requires remove the circuit board, unsoldering the old fuse, and soldering a new fuse in its place.
25 maj 2021 · eFuses are IC based protection devices that are used to limit circuit currents, voltages to safe levels during fault conditions. When connected in series to the power line, it operates like a standard fuse with the ability of detecting and quickly reacting to overcurrent and overvoltage conditions.
This article discusses a simple uninterruptible power supply that can come in handy in various situations. The design contains a rechargeable Li-Ion battery, battery protection and charging circuitry, and a 12V step-up module.
25 lip 2001 · The replacement process requires you to remove the circuit board from the housing, unsolder the blown fuse from the circuit board, and then solder the new fuse back in place.
Find a detailed power supply board circuit diagram and learn how it functions to provide electrical power to various electronic devices. Understand the components and connections involved in the circuit diagram to troubleshoot and repair power supply issues.
18 mar 2021 · In this article, we will look at the individual components of a PSU, then design a small 12V supply from scratch, and an adjustable dual 1-30V supply. The mains input section contains the connections to the mains, usually a switch, a fuse, and a pilot lamp of sort.
Before commencing the repair, gather together any relevant circuit diagrams, known good boards, and appropriate test equipment such as a DMM, solder/desolder hand tools, an oscilloscope, power supplies, etc. (Figure 2), referably on a static-free bench.
