Every electronics workshop or mobile phone repair center should have an adjustable voltage source on its workbench. When a device brought in for repair does not have its original battery or adapter, a professional laboratory power supply is used to power it on and monitor current leakage in the circuit.
For beginners entering the electronics field in Baku or professionals establishing a service center, choosing the right equipment helps prevent unnecessary financial losses.
The most commonly used standard model in laboratories is the 30V 5A power supply. This device allows precise adjustment of voltage from 0 to 30 volts and current from 0 to 5 amps.
Structurally, there are two main types of power supplies: linear power supplies and switching power supplies. Linear models use heavy transformers, provide minimal electrical noise and interference, but generate more heat. On the other hand, switching power supplies are more affordable, lightweight, and provide higher efficiency.
In mobile phone repair, this device also works as a short circuit detector. By applying low voltage and high current to a short-circuited circuit board, the faulty overheating component (for example, a shorted capacitor) can be easily identified.
