Digital ammeter ELM-4

flush-mountmeasurement

Ammeter for measuring residual or residual currents (up to four at the same time) using a suitable external toroidal reducer or for measuring line currents (possibly even lines separated from each other) using special external CTs. The main measurement parameters are: • Current (phase) • Differential currents • Maximum instantaneous current measurement • Peak values (max demand) for current measurement • Average value (AVG) for current measurement OPERATIONAL CHARACTERISTICS • Current measurement range: - input 0-1k 1+999 mA - input 0-5k 0,05+5 A - input 0-50k 0,50+50 A - input CT../IA: 1+999 mA - input CT../5A: 0,05+5 A • Accuracy: Current: ±0,5% ±1 digit • Max and AVG measurement storage • RS485 port • Modbus-RTU communication protocol • 2 pulses outputs • Housing: flush-mount 96x96mm • Degree of protection: IP65 on front; IP20 at terminal
