Energy Management

Energy Analyzer

Type EM111

Product description

Single-phase energy

analyzer with backlit LCD

display with integrated touch

keypad. Particularly indicated

for active energy metering

and for cost allocation in

applications up to 45 A (direct

connection), with dual tariff

management availability.

It can measure imported

and exported energy or be

programmed to consider only

• Single phase energy analyzer

• Class 1 (kWh) according to EN62053-21

• Class B (kWh) according to EN50470-3

• Accuracy ±0.5% RDG (current/voltage)

• Direct current measurement up to 45AAC

• Backlit LCD display with integrated touch key-pad

• Energy readout on display: 7 digit

• Variable readout on display: 4 digit

• Energy measurement: kWh and kvarh (imported/

exported); kWh+ by 2 tariffs

• System variables, kW, kvar, V, A, PF, Hz, kWdmd,

kWdmd peak

• Self power supply

• Dimensions: 1-DIN module

• Protection degree (front): IP51

• Pulse output (optional, by open collector PNP)

• RS485 Modbus port (optional)

• M-bus port (optional)

• Digital input (for tariff management)

• Easy connection or wrong current direction detection

• Certied according to MID Directive (option PF only):

see “how to order” below

the imported one. Housing for

DIN-rail mounting, with IP51

front degree protection. The

meter is optionally provided

with pulse output proportional

to the active energy being

measured, RS485 Modbus

port or M-bus port.
