LayerZero Company Questions

What does the name LayerZero mean?

LayerZero refers to the foundational layer of power distribution products and processes that are required to ensure the reliability and safety of the entire power distribution system in mission-critical facilities such as data centers.

The name "LayerZero" was created on the idea of creating a robust "Foundation Layer" of power system infrastructure for data centers. The company's name, LayerZero, is derived from the Open System Interconnection (OSI) reference model, which provides a standardized architecture for computer network communications. The OSI model is comprised of seven layers, each specifying a particular network function. LayerZero, therefore, refers to the bottommost layer of the OSI model, which is responsible for the physical transmission of power.

"Layer Zero" must be comprised of high-quality products and processes that are designed specifically for the unique needs of data centers and other mission-critical facilities. By focusing on the foundational layer of the power distribution system, LayerZero is able to provide a comprehensive solution that addresses the specific needs of mission-critical facilities. This includes products such as Power Distribution Units (PDUs), Remote Power Panels (RPPs), and Static Transfer Switches (STSs).

The LayerZero approach to power distribution systems is characterized by a strong focus on safety, reliability, and connectivity. The company's products are designed to ensure that power is distributed efficiently and safely throughout the facility, minimizing the risk of downtime or other disruptions. The highly connected nature of the LayerZero system also provides users with valuable data and insights that can be used to optimize the performance of the entire power distribution system.

LayerZero's commitment to creating a robust foundation layer of power system infrastructure for mission-critical facilities has earned the company a reputation as a leader in the field of power distribution systems. The company's focus on safety, reliability, and connectivity has resulted in a comprehensive solution that addresses the unique needs of data centers and other mission-critical facilities.

Since its inception in 2001, LayerZero has been driven by a commitment to creating a reliable, safe, and highly connected set of power distribution products and processes that can serve as the foundation for data centers and other mission-critical facilities. The company's dedication to the foundational layer of power distribution systems has allowed it to become a leader in the field, providing critical infrastructure solutions that enable mission-critical facilities to operate safely and efficiently.

Definition of LayerZero

What is LayerZero?

"LayerZero", also referred to as "the foundation layer", is the lowest layer in the Open Systems Interconnection (OSI) model. Its primary function is to facilitate the reliable transmission and distribution of power to critical equipment on a network. This layer consists of the physical components of the power infrastructure, such as cables, connectors, and power distribution units (PDUs), as well as the protocols and standards that govern the transmission of power at the physical layer.

The physical components of LayerZero are designed to handle the unique requirements of mission-critical facilities. These components must be of high quality to ensure that power is transmitted reliably, without which the entire power distribution system may be compromised, leading to downtime or other disruptions that can have serious consequences for mission-critical facilities.

LayerZero serves as the foundation for the entire network, providing the physical infrastructure necessary to support the transmission of data between devices. It is responsible for power distribution, setting standards and protocols for power management and transmission, and defining the physical characteristics of the network. The physical components and protocols of LayerZero must be of the highest quality, designed and implemented with the unique needs of mission-critical facilities in mind to ensure uninterrupted power delivery.

Who uses LayerZero Products?

LayerZero Power Systems products are designed for operations that require uninterrupted critical power, including data centers, cloud computing, banking, insurance, and medical industries.

One of the main concerns is of data centers is maintaining business continuity; business rely on information systems to run their operations. If a system becomes unavailable, operations may be impaired or stopped completely, often causing serious disruptions to a company's operations, as well as their reputation.

It is necessary to provide a reliable power infrastructure for IT operations, in order to minimize any chance of downtime. A Static Transfer Switch is designed to get you out of trouble - fast. LayerZero provides a last-line of defence in the event of a potential incident, reliably switching power between multiple sources and safely distributing critical loads.

What currents are LayerZero Static Transfer Switches available in?

We offer Static Transfer Switches with 150 A, 250 A, 400 A, 600 A, 800 A, 1200 A, 1600 A, 2000 A, 3000 A, and 4000 A.

What is the difference between an ATS (Automatic Transfer Switch) and STS (Static Transfer Switch)?

An Automatic Transfer Switch (ATS) is a device that is designed to automatically transfer power from one source to another in the event of a power outage. ATS units typically rely on mechanical components, such as relays and solenoids, to switch between power sources. As a result, they may be slower to transfer power than STS units.

In contrast, a Static Transfer Switch (STS) utilizes a solid-state switching component, typically a silicon-controlled rectifier (SCR), to make the transfer between power sources. STS units can transfer power in less than four milliseconds, which is much faster than an ATS. LayerZero's eSTS units, which utilize Dynamic Phase Compensation technology, can delay the transfer until the perfect moment, compensating for out-of-phase sources and reducing the risk of power disruption.

The main difference between ATS and STS units is the speed of the transfer between power sources. ATS units rely on moving parts and may be slower to transfer power, while STS units utilize solid-state switching components and can transfer power much faster.

What is the SafePanel?

The SafePanel is an innovative piece of electrical equipment that has been designed by LayerZero with the primary aim of ensuring the safety of those who come into contact with it. Unlike traditional panel boards, the SafePanel is finger-safe, meaning that it is equipped with features that minimize the risk of accidental electric shocks or other types of injuries.

One of the key features of the SafePanel is its availability in two different sizes: 400 A and 1200 A. This makes it suitable for a wide range of applications, from small-scale installations to large industrial settings. Furthermore, the SafePanel requires IP-20 PPE, which refers to personal protective equipment that is designed to protect against contact with live parts. This level of protection is essential for anyone who will be working with or around the SafePanel, as it ensures that they are shielded from the risks of electrical hazards.

Overall, the SafePanel is a cutting-edge piece of technology that represents a significant advance in electrical safety. With its finger-safe design, two size options, and IP-20 PPE requirement, it is an excellent choice for anyone looking to ensure the safety of their workers or themselves while working with electrical equipment.
