Appliance Coupler
IEC 60320 Appliance couplers for household and similar general purposes is a set of standards from the International Electrotechnical Commission (IEC) specifying non-locking connectors for connecting power supply cords to electrical appliances of voltage not exceeding 250 V (a.c.) and rated current not exceeding 16 A. Different types of connector (distinguished by shape and size) are specified for different combinations of current, temperature and earthing requirements. Unlike IEC 60309 connectors, they are not coded for voltage; users must ensure that the voltage rating of the equipment is compatible with the mains supply. The standard uses the term ''coupler'' to encompass connectors on power cords and power inlets and outlets built into appliances. The first edition of IEC 320 (later renumbered IEC 60320) was published in 1970. Terminology ''Appliance couplers'' enable the use of standard inlets and country-specific cord sets which allow manufacturers to produce t ...

IEC 60320 C5 Connector
The International Electrotechnical Commission (IEC; in French: ''Commission électrotechnique internationale'') is an international standards organization that prepares and publishes international standards for all electrical, electronic and related technologies – collectively known as "electrotechnology". IEC standards cover a vast range of technologies from power generation, transmission and distribution to home appliances and office equipment, semiconductors, fibre optics, batteries, solar energy, nanotechnology and marine energy as well as many others. The IEC also manages four global conformity assessment systems that certify whether equipment, system or components conform to its international standards. All electrotechnologies are covered by IEC Standards, including energy production and distribution, electronics, magnetics and electromagnetics, electroacoustics, multimedia, telecommunication and medical technology, as well as associated general disciplines such as term ...

Pole (electrical Circuits)
A terminal is the point at which a conductor from a component, device or network comes to an end. ''Terminal'' may also refer to an electrical connector at this endpoint, acting as the reusable interface to a conductor and creating a point where external circuits can be connected. A terminal may simply be the end of a wire or it may be fitted with a connector or fastener. In network analysis, ''terminal'' means a point at which connections can be made to a network in theory and does not necessarily refer to any physical object. In this context, especially in older documents, it is sometimes called a pole. On circuit diagrams, terminals for external connections are denoted by empty circles. They are distinguished from nodes or junctions which are entirely internal to the circuit, and are denoted by solid circles. All electrochemical cells have two terminals (electrodes) which are referred to as the anode and cathode or positive (+) and negative (-). On many dry batteries, t ...

Appliance Class
Appliance classes (also known as protection classes) specify measures to prevent dangerous contact voltages on unenergized parts, such as the metallic casing, of an electronic device. In the electrical appliance manufacturing industry, the following appliance classes are defined in IEC 61140 and used to differentiate between the protective-earth connection requirements of devices. Class 0 These appliances have no protective-earth connection and feature only a single level of insulation between live parts and exposed metalwork. If permitted at all, Class 0 items are intended for use in dry areas only. A single fault could cause an electric shock or other dangerous occurrence, without triggering the automatic operation of any fuse or circuit breaker. Sales of such items have been prohibited in much of the world for safety reasons, for example in the UK by Section 8 of The Low Voltage Electrical Equipment (Safety) Regulations 1989and New Zealand by thElectricity Act A typical exampl ...

Power Brick
An AC adapter or AC/DC adapter is a type of external power supply, often enclosed in a case similar to an AC plug. Other common names include wall wart, power brick, wall charger, and power adapter. Adapters for battery-powered equipment may be described as chargers or rechargers (see also battery charger). AC adapters are used with electrical devices that require power but do not contain internal components to derive the required voltage and power from mains power. The internal circuitry of an external power supply is very similar to the design that would be used for a built-in or internal supply. External power supplies are used both with equipment with no other source of power and with battery-powered equipment, where the supply, when plugged in, can sometimes charge the battery in addition to powering the equipment. Use of an external power supply allows portability of equipment powered either by mains or battery without the added bulk of internal power components, and ...

80 Plus
80 Plus (trademarked 80 PLUS) is a voluntary certification program launched in 2004, intended to promote efficient energy use in computer Power supply unit (computer), power supply units (PSUs). Certification is acquirable for products that have more than 80% energy efficiency at 20%, 50% and 100% of rated load, and a power factor of 0.9 or greater at 100% load. History * Electric Power Research Institute, EPRI (Electric Power Research) and Ecos Consulting (promoter of the brand) develop the Generalized Internal Power Supply Efficiency Test Protocol for desktop derived multi-output power supplies. * March 2004: the 80 Plus idea was presented as an initiative at the ACEEE Market Transformation Symposium. * February 2005: the first market-ready power supply was created by Seasonic. * 2006: Energy Star added 80 Plus requirements to their then-upcoming (in effect since July 2007) Energy Star 4.0 computer specifications. * November and February 2006: Hewlett-Packard, HP and Dell cert ...

Power Supply Unit (computer)
A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the mains voltage. Most modern desktop personal computer power supplies conform to the ATX specification, which includes form factor and voltage tolerances. While an ATX power supply is connected to the mains supply, it always provides a 5-volt standby (5VSB) power so that the standby functions on the computer and certain peripherals are powered. ATX power supplies are turned on and off by a signal from the motherboard. They also provide a signal to the motherboard to indicate when the DC voltages are in spec, so that the computer is able to safely power up and boot. The most recent ATX PSU standard is version 3.0 as of mid-2022. Functions The desktop computer power supply convert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Norma Oficial Mexicana
The Norma Oficial Mexicana (Official Mexican Standard), abbreviated NOM, is the name of each of a series of official, compulsory standards and regulations for diverse activities in Mexico. They are more commonly referred to as ''NOMs'' or ''normas''. The standards are prepared by the ''Dirección General de Normas (DGN)'' (Directorate-General of Standards), which is the body representing Mexico in the International Organization for Standardization (ISO). Examples Tequila In the case of tequila, Mexico's Tequila Regulatory Council (CRT) regulates production NOMs. The NOM identifier means the tequila meets government standards - but this is not any guarantee of tequila's quality. However, without the NOM stamp of legitimacy, it is not guaranteed that the bottle contains tequila. All 100% agave tequilas must have a NOM identifier on the bottle. The important laws since 1990 were NOM-006-SCFI-1993 and the later update NOM-006-SCFI-1994 revised in late 2005 NOM-006-SCFI-2005 and th ...
