17. 1 11 Power Supply The supply voltages for the meter are obtained from the three phase net work whereby the phase voltage may vary over the entire voltage range without the power supply having to be adjusted As the power supply even works with only one phase voltage available single phase voltage dips do not affect the operation of the meter A voltage monitor ensures correct operation and reliable data recovery in the event of an all phase voltage interruption and correct restarting when the voltage is restored 1 12 Additional Power Supply Because the three phase network can be switched off in grid metering applications the meter is equipped with an additional power supply in order to prevent the meter from switching off The additional power supply supplies its voltage in parallel to the normal network supply and ensures an uninterrupted operation of the meter so that the meter can be read at any time In a special mode the meter may also be powered by the additional power supply only optional depending on parameter settings As a result there is no load on the line between transformer and meter and voltage drops on the line are prevented 1 13 Transmitting Contacts Module The transmitting contacts module is fitted inside the meter and is therefore secured by verification seals It features up to four changeover contacts or up to eight normally open contacts solid state relays The contacts are used to transmit energy puls
