Carlo Gavazzi Energy Meter EM330 3-phase via CTs

Carlo Gavazzi Energy Meter EM330, 3-phase via current transformers. Three-phase energy analyzer for DIN rail mounting with illuminated LCD screen and integrated touch keypad. The meter is connected via current transformers with a 5 A output and measures active and reactive energy, with input and feed-in separated or summed. Communication via RS485 Modbus RTU. Applications: As soon as the main current exceeds the range of a direct-measurement meter, you measure via current transformers — and then you want a meter built for that. This analyzer reads on-site on an illuminated screen, tracks two tariffs, and transmits the data via Modbus. For cost allocation in commercial buildings, multi-tenant buildings, and industrial installations, this is the workhorse solution. * Heavy three-phase connections where direct metering is not possible * Cost allocation and chargeback per department, tenant or process * Installations with dual tariff management * Two- and single-phase systems, in addition to three- and four-wire three-phase systems * Metering setups in which both working and reactive power must be recorded Metering * Current input 5 (6) A via current transformers; CT ratio adjustable * Suitable for three-phase 3- and 4-wire, two-phase 3-wire, and single-phase 2-wire systems * Active and reactive energy * Input and feed-in can be recorded separately or summed to a single total * Measures input only if desired Tariffs and outputs * Two tariffs, controllable via the digital input or via a Modbus command * Digital input: contact open is tariff 1, contact closed is tariff 2 * Optionally a pulse output proportional to the measured active energy Communication * RS485 with Modbus RTU via screw terminals * Up to 247 devices on the same bus * For cable lengths exceeding 1000 m, a signal amplifier is required; only the last device in the line is terminated * Also available in an M-Bus or pulse version; Please check which version you need when ordering. Version * DIN rail housing * Illuminated LCD screen with integrated touch keypad * Protection class IP51 on the front * Auxiliary power supply 90 to 260 V AC/DC * Available in a MID-certified version for statutory metrology Can be ordered directly with this * Carlo Gavazzi measuring coil 100 A solid core (https://shop.top.systems/installatie/energiemeters/carlo-gavazzi-meetspoel-100a-vaste-kern.html) (REL200201330).
