Voltage measuring instrument EMM-µD3h

currentdigitalmultifunction

The EMM-D... digital multimeters are made in DIN modular housing, 3 and 6 module. The TRMS measurements allow correct operation even in critical conditions. The main measurement parameters are: • Voltage (line and total) • Current (phase and total) • Power (active, reactive, apparent phase and total) Cosφ (phase and total) • Maximum instantaneous values of voltage and current active power, reactive power and apparent power • Peak values (max demand) • Average value (AVG) for powers and currents • Hour counter • Active, reactive and apparent energy meters (partial and total with programmable tariff functions) • Bidirectional active and reactive energy meters OPERATIONAL CHARACTERISTICS • voltage measurement range: 20...500VAC I-L 20...290VAC 1-N • Current measurement range: 0,02...5A • Operating frequency range: 45...65Hz • Programmable CT ratio: 1,0...2000 • Accuracy: Voltage: ±0,5% ±1 digit Current: ±0,5% ±1 digit Frequency: ±0,5% ±1 digit Active energy: Class 2 • Total hour meter • Max and AVG measurement storage • True RMS measurements • RS485 port • Modbus-RTU communication protocol • 2 pulses outputs • Modular housing, 3 module (EMM-wD3h only) • Modular housing, 6 module (EMM-D4h only) • Degree of protection: IP65 on front; IP20 at terminal
