Parallel DC stabilized power supply is a common power supply equipment, usually used to provide stable DC power for electronic devices. It has many advantages and some disadvantages, which will be detailed in this article. Firstly, let’s take a look at the advantages of parallel DC stabilized power supply. 1. High reliability: The parallel DC […]

According to the working mode of UPS, it can be divided into online UPS and offline UPS. Offline UPS, also known as various types of UPS, can also be divided into sine wave output, square wave output, with or without voltage regulation. (1) Various types of UPS refer to the inverters in UPS that only

1. Online UPS: Online UPS is the most commonly used type of UPS, which integrates the battery and inverter into one chassis. During normal operation, an online UPS converts mains power into DC power, which is then converted into AC power through an inverter to supply power to the equipment. When the mains power is

A regulated power supply mainly consists of three parts: input circuit, control circuit, and output circuit.Input circuit: used to receive input power supply voltage. It usually includes transformers, rectification circuits, and filtering circuits. Transformers are used to reduce power supply voltage, rectification circuits convert AC power to DC power, and filtering circuits are used to

Battery powered uninterruptible power supplies (UPS) are crucial in protecting sensitive equipment in data centers, medical facilities, factories, telecommunications hubs, and even homes from short-term power grid spikes and outages. In the event of a prolonged power outage, they can provide the necessary short-term electricity to achieve a prepared outage and prevent data loss.UPS can

The working principle of a regulated power supply is based on a negative feedback mechanism. When the input voltage or load changes, the output voltage will fluctuate accordingly. At this point, the feedback circuit will collect the fluctuation signal of the output voltage and send it to the comparison circuit for comparison. The comparison circuit

Switching stabilized power supply is a type of power supply that works by using switching transistors to control the output voltage of the power supply, in order to achieve stable output. Its working principle can be divided into the following aspects: 1、 Classification of Switching Voltage Stabilized Power Supply Before understanding the working principle of

An uninterruptible power supply (UPS) is an electrical device that provides emergency power to a load in the event of a failure in the input power or mains supply.The difference between uninterruptible power supplies and auxiliary or emergency power systems or backup generators is that uninterruptible power supplies provide near instantaneous input power interruption protection

UPS power supply can be divided into two categories based on its working mode: backup and online. According to its output waveform, it can also be divided into two types: square wave output and sine wave output. When the backup UPS power supply is in normal power supply, the mains supply directly provides power to
