Stable power supply is necessary for computers, servers, network equipment, security systems, automation and other equipment. Voltage fluctuations or sudden power outages can lead not only to equipment shutdown, but also to data loss. Uninterruptible power supplies (UPS) are used to protect such systems.
What is the UPS for?
An uninterruptible power supply provides the connected equipment with electricity in case of problems with the main network. Depending on the model, it can also protect the load from voltage surges and deviations. The EKF catalog includes line-interactive models, dual-conversion UPS and equipment of various capacities.
When choosing equipment, it is worth considering not only the technical characteristics, but also an uninterruptible power supply, the price of which corresponds to the expected load and the required battery life.
What are the types of uninterruptible power supplies?
Modern UPS systems differ in design, principle of operation and purpose. The most common options are:
- Line-interactive UPS systems are suitable for computers, office equipment, and other equipment that requires protection from major power grid problems.
- UPS with a pure sine wave is used for equipment that is sensitive to the shape of the output voltage.
- Dual conversion UPS systems are used where stability and quality of power supply are particularly important.
- DC UPS systems are designed for specialized systems and equipment with the appropriate type of power supply.
What to look for when buying
The main parameter is the power. The UPS must withstand the total load of all connected devices with the necessary margin. It is also important to determine how much battery life is required in case of a power outage.
- rated and active power;
- UPS type and energy conversion technology;
- capacity and number of batteries;
- Battery life;
- number and type of output connectors;
- the ability to connect external batteries;
- availability of USB, network management, or SNMP.
UPS for home and business
A compact linear interactive device is usually sufficient for a home computer or a small workstation. The requirements are much higher for server, telecommunication equipment, or industrial automation. In such cases, powerful dual conversion models, including three-phase solutions, can be used.
The EKF catalog includes UPS systems for various purposes and capacities, from compact models.
