Why Lento Static Ups is Better Than Other Inverters?

The off Line UPS above 1.5KVA are highly unreliable and not available with any brand. The ON Line UPS always wastes 10-15% electricity. i.e. power Loss. About 40% Loss due to poor power Factor is additional to the above. for the applications where the fully regulated voltage and frequency is not required, the static UPS is the best solution. It provides of an Online UPS and with negligible power loss when input Mains AC is present.

What is an inverter?

An inverter converts DC voltage to alternating current voltage. In most cases, the input DC voltage is lower, while the output AC voltage is equal to the grid supply voltage, which can be 120 or 240 volts depending on the country.

The inverter can be designed as a standalone piece of equipment for applications such as solar power or as a backup power supply using batteries that are charged separately.

The other configuration is when it is part of a larger circuit, such as a power supply unit, also known as a UPS. In this case, the rectified mains AC in the PSU powers the inverter, while the rectified AC in the UPS powers it when there is power and the batteries power it when there is no power.

Inverters are classified according to the shape of the switching waveform. These have various circuit configurations, efficiencies, benefits, and drawbacks.

An inverter generates alternating current voltage from direct current power sources and is useful for powering electronics and electrical equipment rated at alternating current mains voltage. Furthermore, they are widely used in the inverting stages of switched mode power supplies. The circuits are classified based on their switching technology and switch type, as well as their waveform, frequency, and output waveform.

What is a Pure Sine Wave Inverter?

Before we get into the benefits of using pure sine wave inverters in your home, it's important to understand what they are and how they work. Pure sine wave inverters produce AC power that closely resembles the real thing - a steady, continuous sine wave with smooth, periodic oscillations. As a result, the price of this solar inverter for home is quite high. Furthermore, certain devices are only compatible with these inverters. If you use another type of inverter, your devices may malfunction or be damaged.

Let us now look at the advantages of pure sine wave inverters.

Advantages of Pure Sine Wave Inverter-

1. Consistent, smoother current flow

A pure sine wave inverter, as opposed to modified sine wave inverters, provides consistent, uninterrupted power to your devices. What makes this so great? Because modified sine wave inverters produce power in a step pattern, the voltage abruptly rises and falls, resulting in inconsistent current flow to your devices, which can be harmful in the long run. When shopping for a solar inverter for your home, it's best to go with pure sine wave inverters.

2. Produces same current as power grids

A pure sine wave produces a wave that is very similar to the smooth waveform generated by mains electricity. That is, there is no discernible difference between plugging your devices into these inverters and plugging them into a wall outlet.

This, of course, means that you can use almost any device during a power outage.

3. Devices are at low risk

The smooth waveform produced by a pure sine wave inverter also protects your high-end electronics from damage during power outages. After all, you don't want your gaming computer or oxygen machine to fail during a power outage.

Furthermore, using modified sine wave inverters with AC-powered devices such as microwaves and refrigerators can generate excessive waste heat, putting your devices at risk. Pure sine wave inverters, on the other hand, pose no threat to any of your devices.

4. Quiet Operation

When using standard inverters, you may occasionally hear an annoying humming sound from lights and fans. When using a pure wave inverter, this is not the case. The waves produced by these inverters make very little noise. Pure wave inverters are simply cleaner, cooler, and quieter.

5. Compatibility With a Variety of Devices

Because of the grid-like wave pattern and power these inverters produce, almost all devices work with them, including:

1. Appliances with AC motors, such as refrigerators, compressors or microwaves.
2. Audio equipment, video equipment, satellite systems, and microwave towers.
3. Other devices that use the same type of technology include bread makers, certain battery chargers, and light dimmers.
4. Many CPAP devices for sleep apnea and oxygen concentrators that require a power source.
5. Furthermore, there is no need to purchase a separate UPS for your computer because a pure wave inverter is more than capable of powering your PC.

So why use a pure sine wave inverter?

• The output waveform is a sine wave with very low harmonic distortion and clean power, similar to that provided by a utility—essential for your expensive equipment.
• Inductive loads, such as microwaves and motors, operate more quickly, quietly, and efficiently.
• Pure sine-wave technology reduces both audible and electrical noise in fans, fluorescent lights, audio amplifiers, televisions, fax machines, and answering machines. It prevents computer crashes, strange printouts, and monitor glitches.

 

Frequently Asked Questions-

Q. What is DSP SineWave?

Description. sine = dsp. SineWave creates a sine wave object that generates a real-valued sinusoid with an amplitude of 1, a frequency of 100 Hz, and a phase offset of 0. By default, the sine wave object generates only one sample.

Q. Is online UPS pure sine wave?

On-line UPS power supply bypass output is pure sine wave： In normal mode (A) : the output of municipal electricity after passing through the inverter is an impure sine wave; Battery mode (B) : the output of impure sine wave after the dc voltage passes through the inverter.

Q. What is meaning of DSP inverter?

Digital signal processors (DSP) based controllers provide the high level of computational performance and programming flexibility needed for the real-time signal processing in solar power inverters.

Q. How do you know if a sine wave is UPS?

Use an Oscilloscope and look for wave pattern if it gives sine or cosine waveform then the inverter is pure sine wave.

Q. What are the 3 types of UPS?

The three major types of UPS system configurations are online double conversion, line-interactive and offline (also called standby and battery backup). These UPS systems are defined by how power moves through the unit.

Q. Is sine wave UPS better?

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.

Q. Why is DSP used?

DSP is used primarily in areas of audio signal, speech processing, RADAR, seismology, audio, SONAR, voice recognition, and some financial signals. For example, digital signal processing is used for speech compression for mobile phones, as well as speech transmission for mobile phones.

Q. What devices need sine wave UPS?

Typically, you'll need pure sine wave inverters for sensitive equipment, newer TV's, CFL light bulbs, and appliances with AC motors (microwaves and refrigerators).

 

 

What is an inverter?

An inverter converts DC voltage to alternating current voltage. In most cases, the input DC voltage is lower, while the output AC voltage is equal to the grid supply voltage, which can be 120 or 240 volts depending on the country.

The inverter can be designed as a standalone piece of equipment for applications such as solar power or as a backup power supply using batteries that are charged separately.

The other configuration is when it is part of a larger circuit, such as a power supply unit, also known as a UPS. In this case, the rectified mains AC in the PSU powers the inverter, while the rectified AC in the UPS powers it when there is power and the batteries power it when there is no power.

An inverter generates alternating current voltage from direct current power sources and is useful for powering electronics and electrical equipment rated at alternating current mains voltage. Furthermore, they are widely used in the inverting stages of switched mode power supplies. The circuits are classified based on their switching technology and switch type, as well as their waveform, frequency, and output waveform.

Why is an inverter necessary?

It is the job of a battery, not an inverter, to store electricity. An inverter's primary function is to convert AC power from power stations into DC power and store it in batteries. Why can't you store this power in the available alternating current form? The answer is that batteries are only charged by DC power and not by AC power. The DC power stored in the batteries must now be converted to AC power in order to power various appliances. Inverters are responsible for this task.

As a result, the inverter converts stored energy into alternating current when it is required to power the house. As a result, in the event of a power outage, this device can be used as a backup.

What are the types of inverters?

Inverters are classified based on their output waveforms, with the three most common types being square waves, pure sine waves, and modified sine waves.

The square wave is simpler and less expensive, but it has lower power quality than the other two. The modified square wave has a higher power quality (THD 45%) and is suitable for most electronic devices. These have rectangular pulses with dead spots between the positive and negative halves of the cycle (THD of about 24%).

True sine wave inverters have the best waveform, with a THD of about 3%. However, it is the most expensive and is used in medical equipment, stereos, laser printers, and other applications that require sinusoidal waveforms. These are also used in grid-connected inverters and equipment.

What are the uses of an inverter?

Inverters are used in a wide range of applications, including small car adapters, household or office applications, and large grid systems.

• Supplies of uninterruptible power
• As independent inverters
• In solar energy systems
• As a component of a switched mode power supply
