Using Sine Wave Inverters to Reduce Harmonic Distortion

Sine wave inverters are a class of power inverters that produce a sinusoidal Alternating Current (AC) of electricity, the kind of current a utility line provides. Consequently, they are used in situations where power is derived from a source of Direct Current (DC) but must be converted into sinusoidal AC to drive equipment that requires [Read More]

Understanding Power Inverters: An Overview

Power inverters convert Direct Current (DC) into Alternating Current (AC), a task that is required for the operation of equipment that draws power from a DC source, but must receive AC to operate efficiently. Buildings that receive power from a DC battery source or solar panels are common examples of environments that need a power [Read More]

Inverter Manufacturers: How to Choose the Inverter Maker

An inverter is like any other electrical device; several companies manufacture it, and choosing the right manufacturer can be challenging for those who don’t have much experience in the matter. If your organization needs to purchase an inverter but needs help evaluating inverter manufacturers, there are three important criteria it can use to make the [Read More]

Sine Wave Inverters: Frequently Asked Questions

Sine wave inverters convert Direct Current (DC) to sinusoidal Alternating Current (AC). Unlike non-sinusoidal current, which has an angular waveform, sinusoidal current has an undulating waveform that represents the “purity” of the current in terms of its oscillation between positive and negative voltages. Whereas non-sinusoidal current commonly produces signs of harmonic distortion, sinusoidal current — [Read More]

Power Inverters: How to Choose the Right Inverter for Solar Panels

Solar panels are a great way to sustainably power commercial buildings. However, before a company enjoys the cost savings and environmental benefits of solar power, it must convert the Direct Current (DC) electricity that the panels produce to Alternating Current (AC) electricity that many types of machinery and appliances use. To facilitate the conversion, a [Read More]

How to Choose the Right NEBS Certified Inverters

In the 1970s, Bell Labs developed a set of standards for electrical equipment used in the Central Offices (COs) of Regional Bell Operating Companies (RBOCs). Known as Network Equipment-Building System (NEBS) standards, the standards gradually became the most trusted certification for electrical equipment in the telecommunications industry and beyond. Today, NEBS inverters are used in [Read More]

Achieving Energy Savings With Power Inverters

Power inverters are designed to change a frequency of Direct Current (AC) to a frequency of Alternating Current (AC). The devices have several residential and industrial applications, some of which result in significant energy savings. One of the best ways to achieve energy savings with power inverters is to use them to convert solar energy [Read More]

Using Sine Wave Inverters to Prevent Harmonic Distortion

A few decades ago, harmonic distortion wasn’t as much of a problem in commercial electrical distribution systems. That’s because the vast majority of electrical loads were linear instead of nonlinear. With the proliferation of solid-state electronics that require nonlinear loads — such as computers, variable-speed drives, and fluorescent lighting ballasts — harmonic distortion has become [Read More]

NEBS Inverters: Frequently Asked Questions

NEBS inverters are the result of equipment compliance standards that Bell Labs developed in the 1970’s. The standards were originally created to make it easy for manufacturers to produce equipment that could be implemented in the Central Office (CO) of a Regional Bell Operating Company (RBOC). Today, after being amended several times to stay abreast [Read More]

NEBS Compliance Certificate: Choosing the Right Certification for an Inverter

Network Equipment-Building System (NEBS) compliance certification originated in the 1970s, when Bell Labs established a set of compliance standards for electrical equipment used in the Central Offices (COs) of Regional Bell Operating Companies (RBOCs). Today, NEBS certification based on three sets of criteria: level 1, level 2, and level 3. The type of NEBS frequency [Read More]
