EM21-72D is an innovative, cost-effective and compact
energy meter: it is the first on the market to have a
detachable display allowing it to be mounted either on a
panel with just 72x72 mm or on a DIN-rail in only 4
modules with neither any adaptor or external accessory.
Certifications on request:
• EC Type examination, Annex B of MID (option"P")
• MID Annex B+F (option "PF") for legal metrology
The main advantages:
• Detachable display allowing three installation modes:
DIN-rail energy meter, panel mounting energy meter and
transducer.
• Space saving on panel boards by means of its compact
housing.
• Energy measurement fulfilling both the new European
standard EN50470-3 and the international standards
IEC62053-21 and IEC62053-23.
• Time saving installation system exploiting self-power
supply, automatic phase detection and application
oriented programming procedure.
• Pulsing output for easy and quick data transmission to
PC/PLC for full load control.
• RS485 communication port for full BMS integration.
