10.8 Powerconsum ptionofmainsconnectedmeter
Thegainedpowerofmetersconnectedto24VACor230VACappearsfromthemarkingonthemeter’sfront.The
markingstatesanaveragemaximumvalueforthemeter’sgainedpower,andoveraperiodoftime,thepowerwill
notexceedthemarking.Forinstanc eshortperiodswithdata
communicationrequireashort‐termincreaseofthe
energyconsumption,whereaslongerperiodswithoutdatacommunicationrequirelessenergy.Thetableshows
examplesofaccumulatedyearlyconsumptionforMULTICAL®603withvarioussupplytypes.Forbatterysupplied
meters,seeparagraph10.3aboutbatterylifetimes.

Thesupplymodulesfor24VACareadjustedforusewitha230/24VACsafetytransformere.g.Kamstruptype66‐99‐
403,whichismountedinacontrolpaneloranotherseparateencapsulation.Regardingpowerconsumptionusinga
safetytransformerinconnectionwith24VACsupplymodules,seeparagraph10.8about
powerconsumptionofmains‐
connectedmeters.
