Energy related Products Directive (ErP) 2009/125/EC

Energy related Products Directive (ErP) 2009/125/EC

From November 20, 2009 the Eco design directive 2005/32/EC (EuP) was replaced by 2009/125/EC (ErP).
The old directive did only cover energy using products, the new directive will still cover energy using products but also include products that are energy related.

The directive 2009/125/EC concerns the environment and how to reduce the use of power. Energy using Products (EuP) is playing an important part in achieving the target of a 20% increase in energy efficiency by 2020. The EuP directive is a framework directive and has already been implemented since July 2005. There will be sub directives to EuP where the different product areas are covered.
Below we describe two of the sub directives concerning External Power Supplies directives, and Off-mode & Standby mode directive. The US have already implemented similar directives, for example CEC (California Energy Commission) level IV and Energy Star. The EuP directive and Energy Star contain the same basic demands. There will not be any special label on the products for the EuP as there is for CEC. It will be covered by the CE marking in Europe.
There are around 27 product areas that will be covered in the future but for the moment it’s just a few mandatory ones and some in draft stage. 2009/125/EC Directive (all language): http://ec.europa.eu/enterprise/eco_design/dir2005-32.htm

What is ECO-Design
The environmental impacts of EuP take various forms, such as energy consumption and related negative contribution to climate change, consumption of materials and natural resources, waste generation and release of hazardous substances. Eco-design involves integrating the environmental considerations at the design phase, thus improving the overall environmental performance of the product.

External Power Supplies (Sub directive to ErP)
The external power supplies sub directives concerns no-load condition electric power consumption and average active efficiency of single output external power supplies. It is scheduled for formal adoption by the Commission in the beginning of 2009 and mandatory 1 year later (2010).
This Regulation shall not apply to:

  • Voltage convertors. (means a device converting 230V mains power source output to 110V power output with characteristics similar to mains power source output characteristics)
  • Un-interruptible power supplies, UPS. (means a device providing automatically backup power when the electrical power from the mains power source drops to an unacceptable voltage level)
  • Battery chargers (a device which connects directly to a removable battery at its output interface)
  • Halogen lighting convertors.
  • External power supplies for medical devices.
  • External power supplies placed on the market no later than 30 June 2015, as a service part for an identical external power supply which was placed on the market not later than one year after this. Regulation has come into force, under the condition that the service part, or its packaging, clearly indicates the primary load product(s) for which the service part is intended to be used with.

The Stage 1 requirements correspond to the mandatory requirements set in federal US legislation, applicable as of 1 July 2008, and the Stage 2 requirements correspond to the new specifications (Version 2.0) of the US Energy Star programme for external power supplies.

Stage 1 demanding from 27 April 2010.

The no-load condition power consumption shall not exceed the following limits:

AC-AC external power supplies, except low voltage external power supplies AC-DC external power supplies except low voltage

external power supplies

Low voltage external power supplies
Po = 51.0 Watts 0,5W 0,5W 0,5W
Po >51.0 – 250Watts 0,5W 0,5W n/a

The average active efficiency shall be not less than the following limits:

AC-AC and AC-DC external power supplies, except low voltage external power supplies Low voltage external power

supplies

Po = 1.0 Watt 0,500 · Po 0,500 · Po
1.0 Watt < Po = 51.0 Watts 0,090 · ln(Po) + 0.500 0,090 · ln(Po) + 0,500
Po > 51.0 – 250Watts 0,85 0,85

Stage 2 demanding from 27 April 2011.

The no-load condition power consumption shall not exceed the following limits:

AC-AC external power supplies, except low voltage external power supplies AC-DC external power supplies except low voltage

external power supplies

Low voltage external power supplies
Po = 51.0 Watts 0,5W 0,3W 0,3W
Po >51.0 – 250Watts 0,5W 0,5W n/a

The average active efficiency shall be not less than the following limits:

AC-AC and AC-DC external power supplies, except low voltage external power supplies Low voltage external power

supplies

Po = 1.0 Watt 0.480 · Po + 0.140 0.497 · Po + 0.067
1.0 Watt < Po = 51.0 Watts 0.063 · ln(Po)+ 0.622 0.075 · ln(Po)+ 0.561
Po > 51.0 – 250Watts 0.87 0.86

Where Po is the Nameplate Output Power of the unit under test. ln refers to the natural logarithm. “low voltage external power supply” means an external power supply with a nameplate output voltage of less than 6 Volts and a nameplate output current greater than or equal to 550 milliamperes. “average active efficiency” means the average of the active mode efficiencies at 25%, 50%, 75% and 100% of the nameplate output power. “active mode” means a condition in which the input of an external power supply is connected to the mains power source, and the output is connected to a load.

Standby and off mode Directive (Sub directive to ErP)
It is scheduled for formal adoption by the Commission end 2008/2009 and mandatory 1 year later (2010).

List of energy using products covered by this Regulation
1. Household appliances
2. Information technology equipment intended primarily for use in the domestic environment
3. Consumer equipment
4. Toys, leisure and sports equipment

Requirements for Off-mode & Standby mode

The off-mode & standby-mode condition power consumption shall not exceed the following limits:

Mode After 1 year  (7 Jan. 2010) After 4 year  (7 Jan. 2013)
Off-mode 1W 0,5W
Standby mode Reactivation function, 1.00 W.

Reactivation function and information or status display,  2W

Reactivation function, 0,5W

Reactivation function and information or status display, 1W

Equipment shall, where appropriate, offer a power management function that switches equipment, after the shortest period of time to standby or off mode.
