Voltage measuring instrument EMM-μD3VA

currentdigitalDIN rail

The EMM-... VA digital multimeters are made in a modular 6-module housing. The measu- rements made in TRMS (True Root Mean Square / true effective value) allow correct operation even in critical conditions. The main measurement parameters are: • Voltage (line and total) • Current (phase and total) • Frequency (frequency of the measured voltage) • Maximum instantaneous values of voltage and current • Peak values (max demand) • Average value (AVG) for voltages and currents OPERATIONAL CHARACTERISTICS • Voltage measurement range: 20...500VAC L-L 20...290VAC L-N • Current measurement range: 0.02...5A • Operating frequency range: 45...65Hz • Programmable CT ratio: 1,0...2000 • Accuracy: ±0,5% ±1 digit • Max and AVG measurement storage • True RMS measurement • Modular housing, 3 module • Degree of protection: IP65 on front; IP20 at terminal
