What is UPS and IPS?


What is UPS and IPS?

Nowadays many of us use IPS and UPS but do not know the difference between IPS and UPS. As a result we can't decide whether IPS is better or UPS is better for us.

The main function of both IPS and UPS devices is to provide backup power supply in case of mains power failure. Generally we use IPS and UPS to manage the electronic devices during power outage.

Although the two devices work the same, there are quite a few differences between them. In this article we will discuss the difference between IPS and UPS in detail. And what is the work of IPS and UPS? I will tell about this.

Difference Between IPS and UPS

Compared to UPS, IPS is able to provide more power backup. Also UPS has much lower voltage than IPS.

Before understanding the difference, let's know what IPS and UPS work. IPS and UPS are basically power supply i.e. IPS or UPS provide power from their stored charge when there is no power connection.

Again when electricity comes it is charged. Now the point is that the two work in the same way, so where is the difference? Talking about the main differences, there are real differences between their devices, time, and capacity.

What is IPS?

The full form of IPS is Integrated Power System. The battery connected to it stores the electricity through charging and when the electricity goes out, it is possible to run all the electrical appliances by supplying electricity for a specified time. IPS are generally of 2 types.

1. Electric IPS – Electric IPS takes charge directly from the mains and stores it in the battery and later supplies power when there is no power.IPS stands for Instant Power System which basically works as Power Storage. IPS is a device that reserves electrical power and later provides back up in case of main line or power supply outage. Unlike Back Up, IPS cannot provide power in the event of a power outage. Automatically provides supply after 1/10 Sec. UPS provides back up for short time but IPS provides multiple back up compared to UPS. Hence IPS is more popular in driving various electrical appliances.

Provides power to home or office appliances such as lights, fans, TVs, video players, audio-players, faxes, PABXs, etc. Currently IPS is also suitable for use in homes, business premises, offices, conference rooms, restaurants, medical departments, testing labs and apartments.

What is UPS?

The full name of UPS is Uninterruptible Power Supply. UPS is an electrical device that can store electricity for some time. And can supply power to computers and other equipment at any moment. UPS is generally different from Emergency Power System or Standby Generator. Because it can provide instant silent power. It is activated when the power is disconnected.

UPS batteries store some electrical energy. As a result, if there is a sudden power outage, the stored power can be supplied from the battery usually within one to two milliseconds. In the main system, the load is directly connected to the input power. When the Main Power Supply fails to connect, it starts its operation

Difference between IPS and UPS:

While IPS and UPS have some similarities, there are many differences between them. The difference between IPS and UPS is discussed below-

1. A UPS usually first supplies current directly to the UPS from the mains. This current is converted from AC to DC and continuously charges the battery. The power from the charged battery goes to the sine wave inverter where the DC is converted back to AC. From this AC we get power to the PC. Since the output power supply comes from DC, its time difference never changes. So the frequency remains unchanged all the time.

On the other hand, in IPS the mains supply current goes directly to the inverter. This mains supply is the same

Time also goes to the output. That is, at the same time the mains supply charges the battery and powers the output. The IPS has a sensor and relay mechanism that constantly checks whether power is coming from the mains supply. Whenever the mains power goes off, it triggers and starts charging the battery.

2. Generally, it takes 3 to 8 milliseconds to transfer power from mains to battery or from battery to mains in a UPS. It is very short and

This time can have no effect on the content used. On the other hand, IPS takes about 500 milliseconds.

3. The power of UPS is usually 2 kVA. On the other hand, the power of IPS is around 16 kVA or more and it is 3 phase.

4. UPS has automated voltage regulation and is usually set at 220. On the other hand, in IPS the voltage is equal to the mains voltage.

5. Normally the mains supply current is one hundredth of a sine wave. But the output of the UPS looks a bit like a square wave. On the other hand, the output of IPS looks more like a step wave. Inductive load loss in IPS is due to the fact that none of the pure sine waves are available. This is the reason why people who run IPS often hear of broken regulators.

6. The mechanism of UPS is more expensive and complex than that of IPS.

7. IPS (IPS) = Instant Power Supply (instant power supply). On the other hand, UPS = Uninterruptible Power Supply.

Offline/Standby UPS

In Offline/Standby UPS, the load is directly connected to the input power in the main system. When the Main Power Supply fails to connect, it provides Power Back-Up.

Battery backup time

For both IPS and UPS, battery backup time is crucial. It indicates how long the system can provide power during an outage. Consider the estimated duration of power outages in your area and choose a backup time that meets your needs. Note that higher backup times usually come with larger and more expensive battery units.

Outlets and connections

Check the number and type of outlets available in UPS and UPS. Make sure it has enough outlets to accommodate your devices Additionally, verify the type of connection provided (eg, standard plug, USB port, Ethernet port) matches your specific needs.


If you are considering a UPS, pay attention to protection and capacity. Look for a UPS that provides adequate protection to protect your valuable electronic devices from power and voltage fluctuations. Higher-end models may offer better surge protection.


Be sure to select the size before purchasing IPS and UPS. Determine where you plan to place it and make sure it will fit in the space. Some models are designed to be mounted accordingly.

Monitoring and management features

Advanced IPS and UPS systems can offer monitoring and management features. These may include LCD displays for monitoring power status, software interfaces for remote management and control, and audible alarms to alert you during power events. Determine the required features for your needs.

Service or Warranty

Check the warranty and support options provided by the manufacturer A reliable warranty and good customer support can give you peace of mind and help in case of any problems with IPS or UPS.

Price and budget

Determine your budget for an IPS or UPS and compare prices between different models and brands. While cost is essential to consider, also focus on features and specifications that align with your needs.

Brand selection

Research and consider good brands known for manufacturing reliable and high-quality IPS and UPS systems. Read reviews thoroughly and gather feedback from other users to get an insight into the performance and durability of different models.

By considering these factors, you can make a sound decision and select an IPS or UPS that meets your specific power backup and protection needs.
