Product description
Single-phase energy meter with electro-mechanical data displaying; particularly indicated for active energy metering and for cost allocation in applications up to 45 A (direct connection), especially when energy reading is necessary during power down. Housing for
DIN-rail mounting, with IP51 front degree protection.
The meter is provided with pulse output proportional to the active energy being measured.
MID
Certified according to MID Directive, Module B and Module D of Annex II, for legal metrology relevant to active electrical energy meters (see Annex V,
MI003, of MID). Can be used for fiscal (legal) metrology.
