4 Minimizing of negative impact on environment during the whole life-time!!! Minimizing of negative impact on environment during the whole life-time!!! Minimizing of consumption of electrical energy (during all possible operating states) Minimizing of consumption of electrical energy (during all possible operating states) –Stand-by mode (max. power), –Active mode (min. efficiency) Technical requirements for Ecodesign Dir. 2009/125/ES - Vyhl. MPO 337/2011 Sb.

5 Ecodesign: Minimizing of consumption for electrical Equipment - examples Council directive of EU: - Electrical equipments for household usage - Light sources, - External power sources, - El. drivers fro 0,75 kW up to 375 kW, - TV sets, - Freezers and fridges for household usage, - Washing machines for household usage, - Fans with el. Driver from 125 W up to 500 kW, - Water pumps, - PC, ITC, servers - Vacuum cleaners - transformers -...., This directives are obligatory in all member states of EU directly!

6 Technical requirements on electro technical goods related to: Electromagnetic compatibility Dir. 2004/108/EC - NV 616/2006 Equipment shall be so designed and manufactured, having regard to the state of the art, as to ensure that: the electromagnetic disturbance generated does not exceed the level above which radio and telecommunications equipment or other equipment cannot operate as intended; it has a level of immunity to the electromagnetic disturbance to be expected in its intended use which allows it to operate without unacceptable degradation of its intended use. Equipments are: Apparatus Fixed installation (newly, since 2006)

7 Electromagnetic compatibility (1) Overview of required basic tests given by „Generic standards“ Testing of emissions: Testing of emissions: high frequency electromagnetic field radiated through cover in the range 30 MHz up to 1 GHz, high frequency electromagnetic field radiated through cover in the range 30 MHz up to 1 GHz, high frequency electromagnetic filed spreading via conductors (power lines) in the range 150 kHz to 30 MHz high frequency electromagnetic filed spreading via conductors (power lines) in the range 150 kHz to 30 MHz harmonic and inter-harmonic components of power line currents (up to 2 kHz) harmonic and inter-harmonic components of power line currents (up to 2 kHz) ripple of supply voltage, flicker effects ripple of supply voltage, flicker effects During all test, emissions can not exceed levels given by harmonized standards!

8 Supply voltage and current consumption of PC power DC source Supply voltage and current consumption of LED lights Supply voltage and current consumption of LED lights Emission of harmonic components into distribution network caused by SMPS Power factor (P/S) vary from 0,5 up to 0,8.

9 Electromagnetic compatibility (2) Basic test of apparatus given by harmonized standards in EU Testing of electromagnetic immunity by applying: Testing of electromagnetic immunity by applying: HF electromagnetic filed (80 MHz up 1 GHz) HF electromagnetic filed (80 MHz up 1 GHz) HF signals spreading through conductive lines (150 kHz up 80 MHz) HF signals spreading through conductive lines (150 kHz up 80 MHz) electrostatic discharges electrostatic discharges fast transient burst (5/50 ns, 5 kHz) fast transient burst (5/50 ns, 5 kHz) surges (1,2/50 μs) surges (1,2/50 μs) Short decrease of supply voltage Short decrease of supply voltage Short interruptions of supply voltage Short interruptions of supply voltage Disturbance is simulated by testing signals described in harmonized standards. We are observing how the equipment under test (EUT) fits one of the following criterions: Disturbance is simulated by testing signals described in harmonized standards. We are observing how the equipment under test (EUT) fits one of the following criterions: EUT works without any worsening of properties (class A) EUT works without any worsening of properties (class A) EUT exhibits temporarily worsening of operation during test (class B) EUT exhibits temporarily worsening of operation during test (class B) EUT needs restart (set-up) after testing - losing of operation capability. (class C) EUT needs restart (set-up) after testing - losing of operation capability. (class C)

10 Electromagnetic compatibility (3) Requirements on EMC of fixed installations: Fixed installation:. Fixed installation does not have a CE mark and Certificate of Conformity Fixed installation: Fixed installation’ means a particular combination of several types of apparatus and, where applicable, other devices, which are assembled, installed and intended to be used permanently at a predefined location. Fixed installation does not have a CE mark and Certificate of Conformity Special requirements on fixed installations: Special requirements on fixed installations: A fixed installation shall be installed applying good engineering practices and respecting the information on the intended use of its components, with a view to meeting the protection requirements set out in Directive. Those good engineering practices shall be documented and the documentation shall be held by the person(s) responsible at the disposal of the relevant national authorities for inspection purposes for as long as the fixed installation is in operation.
