with 5A CT connection
Carlo Gavazzi introduces the EM330 3-phase energy meter with 5A CT input. As with all meters in EM300 Series, the EM330 utilises touch screen technology making standard user operations such as page scrolling, programming and parameter checks not only simpler but faster; as well as, easier to read avoiding any mechanical issues normally associated with using traditional keypads.
EM340 is housed in a 3-DIN module and offers outstanding ease of use, performance and measuring of imported and exported energy.
The EM330 3-phase energy meter with 3×8 digit backlit LCD data display and integrated touch keypad; suited to active energy metering, cost allocation and dual tariff management. The meter is optionally provided with pulse output as an alternative to the serial communication via RS485 Modbus port or M-bus output.
A selection of variables can be programmed to display providing for active and reactive energy measurement, options include: system variables such as kW, kvar, kVA, VLL, VLN, PF, Hz, kWdmd, kWdmd peak; phase variables including kW, kvar, kVA, VLN, A, PF. Energy measurement: kWh and kvarh (imported/ exported); kWh+ by 2 tariffs; kWh per phase.ENDS
