Digital power meter NR30IoT

three-phaseDIN rail

Destined for direct (up to 63A) and indirect measurements in 3 phase 4 wire/3 wire balanced and unbalanced systems in IoT applications. -Measurement and recording of 54 power network parameters in 1-phase 2-wire or 3-phase 3 or 4-wire balanced and unbalanced systems. -Harmonics up to 63rd for current and voltage -MQTT protocol - ideal for IoT applications -Backlight LCD screen, fully configurable by a user -22 pages, 3 parameters in each -1 page with harmonics presentation -Indications include the values of programmed ratios -Memory of minimum and maximum values. -2 configurable alarm outputs. -Mode of supervisory relay for alarm outputs - additional function -To make function active, please order appropriate licence key – details in ordering code. Function can be also activated on the devices which have been alredy installed on the facility after softwate upgrade. -Supervisory relay mode enables detection of following events: -voltage drop or growth -current drop or growth -phase loss -current or voltage unbalance -phase sequence User can specify: -the thresholds of monitored events -monitoring of phase relay -memory of relay state -delay of switch-on/off relay -relay state after the event has occured. -Optional: with additional module of analog outputs - S4AO type (4 current or voltage outputs) -RS-485 digital output - MODBUS protocole -Logging of up to 32 measured parameters in the internal memory 8 GB
