Energy Meter รุ่น EM10-DIN
คุณลักษณะ
Carlo Gavazzi is proud to introduce its compact EM10 and EM11 Series Energy Meters. The EM10 Series is an innovative single-phase energy meter which monitors 120 or 230VAC. It provides a cost effective solution for most metering applications, allowing an effective energy measurement without the need for an external current transformer. This ultra-compact device can easily be interfaced with a PLC, thanks to its optional pulse output (1 Wh resolution). It is ideal for use in public buildings, offices, condominiums, apartments and in most facilities that require energy cost sharing and the metering of common loads. The main technical features of the EM10 Series include:
- Self power supply: One-phase 120 or 230VAC Class B, in compliance with EN50470-1-3
- Readout: 5+1 digit
- Direct connection up to 32A
- 90 x 67.5 x 17.5mm (HxWxD mm) 1-DIN module
- 1 pulse output on request (1000 pulses/kWh)
- IP40 protection degree
