What type of ups

The power supply or charger unit that comes with the computer serves to recharge the battery as needed when the charge level drops off from use. If the laptop or tablet is connected to the power supply and the user is working on the computer, a sudden loss of utility power will prevent the power supply from any further recharging of the battery during the outage period, but from the perspective of the user, they do not experience any downtime or outage.

The onboard battery continues to provide power to the PCBs within the computer, such as the CPU, so no loss of data occurs. This example sets the framework for how the other configurations of UPS systems function, which will be outlined in the next section. A standby UPS is a configuration in which a battery backup is charged by the line voltage and is fed through an inverter to a transfer switch.

When the prime power is lost, the transfer switch brings the standby power path online represented in figure 1 below as the lower path with the dashed line.

The need to actively switch the power path does mean that there is a brief outage that will occur from the time that primary power is lost until the switchover is complete. The primary power path shown in Figure 1 includes an LC filter and surge protection circuitry for noise isolation.

The laptop example that was presented earlier might be considered a simplified type of standby UPS where the desired output is DC instead of AC and no transfer switch is needed. One of the most commonly used designs for an uninterruptable power supply is the line-interactive UPS, presented in Figure 2 below.

With the line interactive design, prime power is fed through a transfer switch to an inverter and then out to the load. The inverter in this design is always active and when prime power is on, it operates in reverse to convert incoming AC power to DC which is used to keep the backup battery charged.

If the line power goes out the transfer switch opens and the inverter works in the normal direction, taking the DC power from the battery and converting it to AC to supply to the load. This design which keeps the inverter active provides improved filtering and reduces the switching transients that could be present with the standby UPS configuration.

Depending on the inverter design, this configuration can provide two independent power paths for the load and eliminates the inverter as a single point of failure.

So even if the inverter were to fail, AC power can still flow to the output. This type of UPS offers low cost, high reliability, and high efficiency, and can support low or high voltage applications. The standby-ferro UPS uses a three winding transformer to couple the load to the power source, as shown below in Figure 3.

Prime power flows through a transfer switch that is normally closed to the coils in the transformer where it couples to the secondary coil of the transformer and then supplies the power to the output load. If the UPS switches to operate in battery mode, it either produces sine wave or simulated sine wave electricity to power your electronics. You will notice the simulated sine wave output has a power gap at each cycle. Sometimes this power gap may cause stress in the power supply in sensitive electronics, harming them.

Electronic equipment with Active PFC power supplies may shut down unexpectedly when using a UPS with simulated sine wave output, resulting in data loss or equipment damage.

UPS systems that deliver sine wave output prevent unexpected shutdowns and damaging electronic stress. If you need help determining whether a device uses Active PFC circuits, contact the device manufacturer. What do I want my UPS to look like? UPS systems have form factors.

The form factor of a UPS indicates the shape and size of its housing. The most common 3 types are: Desktop or compact Tower or mini-tower Rackmount. When choosing the form factor, the main consideration is where you are going to use it. A desktop or compact UPS can hide under a desk, unnoticed. A tower or mini-tower will have a pleasant aesthetic design making it an option to sit on top of a desk or table. A rackmount UPS works well in server rooms. Where do I pick out my UPS system?

These are most commonly caused by severe weather, utility power shortages, accidents, and power grid failures. Brownout — An intentional or unintentional drop in voltage for an extended period of time.

In emergency conditions, power companies may lower the voltage of your electricity to reduce strained resources and avoid a total blackout. Over Voltage — Occurs when incoming voltage is higher than normal and lasts longer than a surge but not high enough to be classified as a surge or spike.

Frequency Noise — Also known as line noise, frequency noise can disrupt or degrade the performance of a circuit by injecting abnormalities into the system. Frequency Variation — Not a common problem when power supplies are stable, but it can occur when using generators and power frequency fluctuates more than desired. Harmonic Distortion — A departure from the ideal electrical signal on a given power source. Here is an example of an equipment list to verify the load: Once you have calculated your load, count the number of power cords you want to connect to the UPS.

A line-interactive UPS will maintain performance during low voltage situations and short-term power failures. If a lengthy outage is anticipated, its battery power allows devices to be shut down safely. Some live interactive units also offer filtering features. Before buying a power protection unit, you may want to compare on-line versus line-interactive UPS technology.

A line-interactive UPS adds an autotransformer to the basic standby design. It has the capability to increase or decrease voltage output. This transformer responds to changes in the AC power and can automatically regulate issues. In comparison, online UPS models use an inverter to transmit all or some of the power, at all times. It takes an interactive UPS a matter of milliseconds to switch into battery backup mode when a failure occurs. Reliable power management systems help to ensure that electrical power to valuable equipment is never interrupted.

When buying a UPS unit, the volt-ampere VA rating of the device should be compatible with the total load that must be protected. This load will include all equipment and network accessories. An advanced online UPS system uses double conversion technology for power management. It delivers consistently clean power, even during the brownout or blackout, for server-grade and data centre systems.
