6 FAQs about [How to detect battery in regulated power supply]
What is a regulated power supply?
A regulated power supply has a voltage regulator which ensures that the power supply’s output voltage will always remain at the rated value regardless of changes in the load current or the input voltage. As a result, any change in the input voltage won’t impact the output voltage.
How do you measure a regulated power supply?
With a few exceptions, the middle is positive, so use the red lead there, and use the black lead on the outside shell. Regulated supplies, without any load, should measure very close to the target voltage of 12v. Unregulated supplies will generally have a no-load voltage anywhere from a couple of volts to several volts higher.
How do I troubleshoot a regulated power supply?
Stereos and communications receivers will most likely use a regulated power supply similar to that shown in figure 1. Start troubleshooting by checking the output voltage with a DMM connected between point D and ground. If the voltage is correct (per manual specs), your problem lies elsewhere.
How do you check the output voltage of a portable system?
Any system is powered by battery or a transformer-rectifier supply connected to the 220-V lines. Batteries usually power portable system. A 9-V battery is most common. To check its output voltage, turn the system on (to load the battery) and measure the battery’s terminal voltage.
Does a regulated power supply change the output voltage?
As a result, any change in the input voltage won’t impact the output voltage. A regulated power supply with multiple regulators can also offer multiple output voltages for operating different devices.
What devices rely on regulated power supplies?
Many devices requiring stable voltage – such as lab equipment, medical devices and computers – rely on regulated power supplies. What's the difference between a regulated and unregulated power supply? While regulated power supplies regulate the output voltage, unregulated power supplies do not.
