Power Supplies

FAQs

How does a power supply work?

A power supply unit converts electrical energy from a source such as AC power, into a usable form like DC voltage. It regulates the output voltage for consistent and safe use. Modern designs focus on efficiency to produce less heat and consume less power.

What is a 100% full load burn-in test?

A 100% full load burn-in test is a quality assurance process where a power supply unit is operated at its maximum power consumption capacity for an extended period. This ensures the unit can handle its rated output voltage and current reliably to prevent any issues. This test is especially important for future upgrades in demanding applications.

What is the maximum output voltage and current for most DC power supplies?

The maximum output voltage and current for most DC power supplies vary but typically range up to 30-60 volts and 3-10 amps for general-purpose models. Specialised units such as battery chargers or AC adapters, may offer different ranges, and high-power industrial models can exceed these depending on their design.

What are some common features of DC power supplies?

Common features include adjustable output voltage and current, digital displays overload and short-circuit protection and multiple output channels. Many also offer programmable settings for automated testing, semi-modular designs for flexibility, and efficiency features to reduce power consumption.
