FOREWORD

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

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

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

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

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

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

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

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

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

agreement between the two organizations.

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

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

interested IEC National Committees.

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

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

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

misinterpretation by any end user.

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

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

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

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

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

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

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

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

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

Publications.

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

indispensable for the correct application of this publication.

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

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

International Standard IEC 62952-3 has been prepared by subcommittee 65B: Measurement

and control devices, of IEC technical committee 65: Industrial process measurement, control

and automation. ISA-d100.18.01 provided the initial input.

This standard is to be used in conjunction with IEC 62952-1. Is it based on the first edition of

that standard (2016).
The text of this International Standard is based on the following documents:

4 Specific requirements for power sources with energy harvesting
4.1 General

IEC 62952-1:2016, Figure 1 shows the possible various types of power modules that can be

used as a power source within a WCD system level and architecture description.

Power modules are elements for WCD to provide power or supplementary power to the WCD.

4.2 GEHAM and energy harvester
Power Module Type C shall consist of GEHAM and energy harvester.

Annex A provides implementation options how the power source can be designed with the

energy harvester and GEHAM as separated or integrated elements.
GEHAM accommodates the following functions.

• GEHAM shall provide the necessary mechanical interface between the energy harvester

and WCD.

• GEHAM should include any power conditioning such as rectification and voltage control to

ensure that the GEHAM output conforms to this standard.

• GEHAM should provide the power management necessary to ensure that power is stored

in a suitable energy storage capacitor or secondary battery.
• GEHAM shall supply energy at a suitable voltage to WCD.

• GEHAM may include batteries (primary or secondary) as backup in case power from the

energy harvester is insufficient.

• GEHAM should ensure that power is used preferentially from the energy harvester before

using power from the backup batteries included in the GEHAM.

• When the energy harvester supplies voltage above the nominal voltage then the GEHAM

can provide intermediate energy storage capacity that is sufficient to power the device

during high-power cycles.
4.3 Mechanical requirements
4.3.1 Connector

Connection shall be downward compatible with respect to capability of connector options (2, 3,

4, 5-pin options).
Example

If a 2-pin male connector is plugged into a 4-pin female cable end between the energy harvester and GEHAM, the

connection shall work without the additional capability/information provided on the pins not connected.

In cases where a connector is used, IEC 61076-2-101 M12 A-Coded connectors shall be used.

Male connectors shall be on both devices, and cable ends shall be female on both ends.

4.3.2 Flying lead

This document shall accommodate flying lead on either end, connecting to a terminal strip or

similar on either or both devices.

If a flying lead is used to connect to the GEHAM/WCD, then the terminals shall be clearly

labeled with text, for example with + and –.
---------------------- Page: 11 ----------------------
– 10 – IEC 62952-3:2017 © IEC 2017
4.3.3 Cable specification

Cable colors shall be compliant with IEC 60304. In case of a flying lead connection, the cable

shall be between 5 mm and 10 mm in nominal outside diameter.

Wire shall be between 0,3 mm and 1,3 mm in nominal diameter depending on the conductors

in the cable.
4.3.4 Enclosure shape

Enclosed type GEHAMs provide additional mechanical protection through having to fit inside

the WCD similar to Type A and Type B defined in IEC 62952-1.
4.4 Electrical characteristics
4.4.1 General

GEHAM is an interface device between the energy harvester and the WCD. To ensure the

interchangeability, input and output rating of GEHAM shall be complied.
4.4.2 Input rating of GEHAM

Maximum input power (Pi) shall be restricted to the capabilities of the used cable and

connectors according to the regulations for electrical safety.
The maximum voltage (Vi) of the GEHAM shall be 30 V DC.
4.4.3 Output rating of GEHAM

The output voltage of GEHAM shall be DC, non-regulated and the ripple shall not exceed the

stated maximum output voltage.

The maximum output voltage provided may be 5 V DC (for a nominal single battery, 3,6 V

capacity) or 10 V DC (for a nominal dual battery, 7,2 V capacity).

The GEHAM shall be clearly labeled to identify whether it is 3,6 V or 7,2 V nominal.

4.4.4 Protections

It is recommended that WCD have over voltage input protection of >12 V DC for preventing

inadvertent connection of GEHAM.
It is recommended that GEHAM have over voltage input protection of > 30 V DC for

preventing inadvertent connection of harvester and disturbance as for example a surge.

This document does not override or replace the requirements of any hazardous area

certification.
4.5 Communication interface

Pin 2 (see Clause B.3) is available for digital communication interface to provide static and

dynamic information from an energy harvester.
5 Profile for power modules with energy harvesting

The general requirements for the power modules are specified in IEC 62952-1. Table 3

specifies general power module profile selection.

Mechanical options

This Annex A accommodates a variety of connection options including connectors on either or

both ends of the cable connecting external power source to WCD or a flying lead connection

to either or both end. These options for internal GEHAMs are described in Annex A.
