EuP certification to ErP certification scope of different change

Recently appeared in the market a number of claims to support EuP certification. With ErP energy-saving instructions of motherboard. These motherboard often on PCB or prominent place box identifies the EuP certification, certification of ErP. So what is the EuP certification, certification of ErP? Support EuP certification., ErP system board and the general and what is the difference?

Recently appeared in the market a number of claims to support EuP/ErP directive of the motherboard. These motherboard often on PCB or prominent place box identifies the EuP/ErP. So what is the EuP/ErP? Support EuP/ErP system board and the general and what is different? Appliances appear on energy consumption, environmental protection class identifier, is no longer a fresh thing. More common have energy star, TCO, CE and other energy saving standard, and there are less common such as the WEEE logo. Each logo above represents a complete set of relevant energy consumption and environmental protection etc. Content of the control file or specification file, they are the consumers to choose environmental protection and energy saving products of compass, is styled themselves leading design level and the product superiority image symbols. Again in 2009, the European Union introduced in view of the whole system energy consumption control scheme, namely the EuP/ErP directive. Today is to introduce a set of energy-saving standards.

Careful readers can see, in this paper, we use the EuP certification/ErP certification. So the energy consumption standards whether EuP certification or certification of ErP, or both? Actually, EuP certification is the old name of the directive, and after October 31, 2009, it was renamed in ErP.

It has been such a change because ErP directive is bigger, the scope of products for more. So-called EuP certification, the full name is "establishing a framework for the setting of Eco - design requirements for Energy - using Products", the translation is "building Energy consumption product ecological design framework directive". Then the ErP directive, full name is "establishing a framework for the setting of ecodesign requirements for Energy - related Products", in Chinese called "to build ecological Energy related Products design framework directive. As can be seen from the name, EuP certification into ErP certification is the biggest change will be target Products ranging from" Energy Products "to" Energy related Products. In order to explain the meaning of the specification, we have to know first what is the "Energy Products" and "Energy related Products.

The EuP certification, with the definition of energy product range is very wide. Energy-consuming products, refers to a product, when it put on the market and/or put into use, the need to rely on energy input, energy, chemical fuels, or renewable sources) to complete the scheduled work, or is used to produce, transform, and measuring the energy of the products. EuP also includes the production of this kind of product parts, these parts can provide end users with a single components on the market and put into use, and can independently be evaluated its environmental performance.

This man is bad to understand again, we can split. Definition of energy-consuming products actually illustrates two thing:

1. If a product need to consume energy at work, it is energy-consuming products, in addition to the popular TV, air conditioning, computer, household appliances such as refrigerator, boiler, electric motors, circulation equipment, fan and so on are also included in the scope of EuP certification;

2. Parts of these energy products in the range of EuP certification examination. In one of the most common computer, for example, the computer the whole belongs to EuP regulation energy consumption investigation object, but the composition of computer parts, such as the motherboard and power supply, is also the goal of EuP certified products. Understand the EuP certification, let's take a look at what is ErP certification. ErP authentication refers to the energy related products. Refers to energy related products on the market and/or put into use, and during its use have an effect on energy consumption of all goods, including expectations embedded energy related products, for the end user as an independent unit and its environmental performance can be evaluated parts (main board and power supply, etc.), etc. ErP certification compared with EuP certification, extended to as long as it can affect energy, will be built into the goal. Besides EuP certification of the product, other such as heat preservation and heat insulation of equipment, such as Windows, insulation, sealing materials, even the faucet and shower head in the ErP certification specifications.

In the motherboard industry blows "EuP/ErP wind", the energy saving trend is likely to spread to the power industry.

Compared ErP EuP, besides expanding the limits prescribed in energy-saving standards for specific products or change a lot. Such as under the EuP, the shutdown state, energy consumption is less than 2 w products, strict control in ErP to no more than 1 w. Speaking of which, there may be some readers don't understand, is not turned off? And energy consumption? Take a closer look at the socket around you, whether there is those who have no use, but still the plug on the lug plate? That's right, part of the circuit inside the appliance is not you choose to be a "shutdown" stop working. Computers also so, the power plug inserts the 220 v mains socket, as long as the power supply inside began to work, at any time waiting for a response to user boot operation command, similar to this and the mainboard. This design means that the power supply and main board in the shutdown state also need electricity. So the energy consumption situation of them in the shutdown state control would be easy to understand.

What are the implications EuP/ErP on computer?

To introduce the content of the EuP/ErP, energy-saving standard as a scope is very broad, EuP/ErP content almost everything. We need to further understand the EuP/ErP and ordinary users to players, such as desktops, laptops, and main board and power supply equipment. These devices have in terms of energy consumption in the EuP/ErP in detail.

In the new ErP is defined, clearly defines the different types of computer standby power consumption. Such as desktop and one-piece computer, ErP rules regulations came into effect after 6 months, class A products subject to the ErP, idle power consumption may not exceed 50 w. For laptops, highest idle power consumption must be controlled under 31 w. In addition, the sleep mode is also control key of ErP. Desktop computers that are accredited by ErP, sleep mode power consumption must be no more than 4 W, if contain network remote wake-up function, allows increased 0.7 W power consumption, also is the biggest 4.7 W. Such as this, the power consumption of different products for different state control requirements, make up most of the content of ErP.

Some motherboard support EuP/ErP, the user can from the motherboard on the outer package and PCB for identification.

Questions about the power consumption of the machine in the shutdown state, as we also cited a similar example, such as in the main board and power consume electricity shutdown condition. ErP is aimed at this kind of situation do the rules. ErP requires the machine system in shutdown mode power consumption must be less than 1 W, and after the January 7, 2013, if vendor want to ErP LOGO on your product posted, also need to make sure that the product of low power consumption 0.5 W in shutdown mode. In shutdown state, the computer system basically only main board and power supply still "has the right to use electricity, so shut down power control of main board and power supply will become a hot topic in the manufacturers attention.

When you buy the motherboard and power supply, and support functions of ErP component system, when using computer even if you don't remove the socket, energy consumption will be less than 1 w. Need to pay special attention to is that main board and power supply must be certified by ErP at the same time, if there is a didn't pass, will affect the final energy saving effect. In addition, ErP energy-saving requirements are provided for the power supply. Has passed the certification of the ErP power, must ensure that, when 50% of the rated power output, efficiency is above 85%; At 20% and 20% of the rated power output, efficiency above 82%. ErP compared to the provisions of the 80 plus different "card" certification, more concise and clear.

In this era of promoting "green energy", we tend to focus on computer when switch on power consumption status, rarely noticed that even if the computer was turned off, as long as keep connection and power supply, still consumes electricity. Less may be 2 ~ 3 w, but more could be as high as more than 5 w. The emergence of the Eup/Erp directive that all PC makers are starting to focus on products in the shutdown state power consumption status, is expected to make the product more energy saving. Using the Eup/Erp, in turn it off and keep the power supply connection can make the machine the low power consumption to less than 1 W and 0.5 W. Eup/Erp technology application at present stage relies mainly on the motherboard and power supply manufacturers.
