What is a power supply used for?
A power supply is a specialised electrical test instrument that provides a stable and adjustable power source for testing circuits, troubleshooting faults, and verifying electrical designs. Unlike standard adapters or chargers, power supplies allow precise control over voltage and current, making them essential tools in research, development, and laboratory environments.
What are the main types of power supplies?
Power supplies are generally classified into two main types:
- Linear power supplies – Provide a stable and low-noise output but tend to be larger and less energy-efficient.
- Switch mode power supplies (SMPS) – More compact, efficient, and widely used due to their improved accuracy and reliability.
Most modern applications prefer switch mode power supplies due to their superior performance and efficiency.
Why is calibration of power supplies important?
Power supplies generate and regulate key electrical parameters such as voltage, current, power, and resistance. Over time, these measurements can drift from manufacturer specifications, leading to inaccurate testing, design errors, and potential equipment failures. Regular calibration ensures measurement accuracy and compliance with industry standards.
