67 FOREWORD

68 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

69 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

70 international co-operation on all questions concerning standardization in the electrical and electronic fields. To

71 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

72 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

73 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

74 in the subject dealt with may participate in this preparatory work. International, governmental and non-

75 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

76 with the International Organization for Standardization (ISO) in accordance with conditions determined by

77 agreement between the two organizations.

78 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

79 consensus of opinion on the relevant subjects since each technical committee has representation from all

80 interested IEC National Committees.

81 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

82 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

83 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

84 misinterpretation by any end user.

85 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

86 transparently to the maximum extent possible in their national and regional publications. Any divergence

87 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

88 the latter.

89 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any

90 equipment declared to be in conformity with an IEC Publication.

91 6) All users should ensure that they have the latest edition of this publication.

92 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

93 members of its technical committees and IEC National Committees for any personal injury, property damage or

94 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

95 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

96 Publications.

97 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

98 indispensable for the correct application of this publication.

99 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

100 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

121 ELECTRICAL INSTALLATIONS FOR LIGHTING
122 AND BEACONING OF AERODROMES –
123 PARTICULAR REQUIREMENTS FOR SERIES CIRCUIT POWER SUPPLIES
124
125
126 Introduction

127 This standard introduces an open specification for power electronic converter systems

128 (PECS) to be used in aeronautical ground lighting (AGL) series circuit systems. The aim of

129 this open specification is to enable various new technologies to be used within AGL systems

130 while ensuring the safe operation and function of the AGL system based on specific items in a

131 series circuit topology.

132 To clarify the distinction between different series circuit power supplies, a new classification

133 system is introduced in clause 4 of this standard. A base class divides the power supplies into

134 PECS and CCRs. Therefore, within this standard, the term PECS refers to series circuit power

135 supplies belonging to the class General PECS for AGL systems and the term CCR refers to

136 series circuit power supplies belonging to the class CCR for 6.6. ampere systems. The term

137 PECS/CCR refers to both device classes. The class CCR for 6.6 ampere AGL systems

138 corresponds to the traditional series circuit power supplies as defined by the previous version

139 of this standard.

140 In addition to the base class, classes for voltage ranges and construction mechanics are

141 introduced. Where a part of this standard only refers to one or more specific AGL systems,

142 the systems in question will be clearly indicated.

143 The PECS may be non-interoperable with the 6.6 ampere system, but they shall be operated

144 within an AGL circuit with a series circuit topology. Here the degree of interoperability of

145 CCR's and PECS is defined by a reference to a specific primary AGL series circuit system.

146 This version also revises the definitions for the 6.6 ampere system.

147 The maintained version may be partially applicable to PECS dedicated to converting power

148 from a mains supply to power suited for AGL other than series circuit topology. The

149 maintenance work of 61822 into 61820-3-2 started before the writing of the related subparts

150 61820-3-1 and 61820-3-3 had started. This updated version may therefore be partially

151 applicable to PECS dedicated to converting power from a mains supply to power suited for

152 AGL systems with other than series circuit topology.
153 1 Scope

154 This part of the IEC 61820 specifies the requirements for power electronic converter systems

155 (PECS) dedicated to powering aeronautical ground lighting (AGL) circuits with series circuit

156 topology. An example of a traditional implementation is an AGL circuit with 6.6 A RMS

157 nominal current, powered by a constant current regulator (CCR). In addition to revising the

158 requirements for 6.6 A CCR setups, this standard introduces requirements for general PECS

159 for new AGL systems including ones specifically designed for LED based luminaires.

258
259 4 Classification
260 4.1 Base classes
261 The PECS or CCR shall be classified into one of the following base classes:
262 • General PECS for AGL systems

263 o The General PECS for AGL systems may control the AGL fixture brightness via

264 stabilized series circuit primary effective current. The General PECS for AGL

265 systems may also be used in combination with information controlled AGL

266 fixtures. In information controlled AGL systems the AGL fixture brightness level

267 may be independent of the effective current in the primary series circuit.
268 • CCR for 6.6 A AGL systems

269 o The 6.6 A system CCR shall control the brightness levels of the AGL fixtures

270 via stabilized series circuit RMS current with precisely defined maximum
271 current. The 6.6 A CCR category closely follows the definitions from IEC
272 61822:2009 and is capable of operating both halogen bulb and LED based
273 AGL Systems.
274 4.2 Voltage classes

275 The PECS/CCR shall be classified into one of the following categories based on the maximum

276 available output voltage:
277 • Low voltage PECS/CCRs
278 o The maximum output voltage of a low voltage PECS/CCR shall not exceed
279 1 000 V AC
280 • High voltage PECS/CCRs
281 o The maximum output voltage of a high voltage PECS/CCR shall not exceed
282 5 000 V AC

283 NOTE Within this standard the term high voltage refers to voltages greater than 1 kV. In other contexts, this

284 voltage range is often referred to as medium voltage.

285 NOTE For Safety Electrical Low Voltage and Protective Extra low voltage circuit refer to the dedicated standard

286 IEC 61820-3-4.
287 4.3 Construction classes

288 The PECS/CCR shall be classified into one of the following categories based on the

289 mechanical construction:

oSIST prEN IEC 61820-3-2:2023
IEC CDV 61820-3-2 © IEC 2022 10 97/248/CDV

291 A self-contained PECS/CCR is defined as a unit with all its components integral to one

292 individual and purpose-built housing. The self-contained unit takes an input power supply

293 and converts this to a series circuit primary current to power and control AGL fixtures. The

294 complete process of power conversion takes place within the housing of the PECS/CCR

295 with the input and output defined within this document. Self-contained PECS/CCR are

296 typically delivered at the end user in its final form.
297 • Switchgear assemblies

298 A Switchgear assembly is defined as a PECS or CCR consisting of an assembly of sub-

299 parts or modular parts. The complete assembly takes an input power supply and converts

300 this to a series circuit primary current to power and control AGL fixtures. These

301 assemblies consist of parts or modules that perform a subtask of process of the power

302 electronic conversion. The switchgear assembly maybe used to separate low voltage and

303 high voltage parts physically in different enclosures or rooms. Switchgear assembly parts

304 or modules are typically connected and mounted by the end user to finalize the assembly.

305 The degree of interoperability of CCRs and PECS is defined by a reference to a specific

306 primary AGL series circuit system. The 6.6 ampere AGL system is an example of such

307 system.
308 5 Requirements
309 5.1 General

310 The following requirements are grouped into five categories: environmental, functional,

311 performance, and design requirements and protection against electric shock.
312 5.2 Environmental requirements

313 The environmental condition classifications follow the definitions given in IEC 60721-3-3.

314 5.2.1 Environmental conditions

315 A PECS/CCR designed for continuous indoor operation without derating, shall follow the

316 provisions for environmental condition of either E20 or E21, as defined in IEC 61820-1 and

317 under one of the following temperature ranges:
318 • Indoor temperature range: from +5 C to +40 C (3K3);
