Single-phase electric energy meter QE-POWER-M

DIN railRS-485Modbus

The QE-POWER-M is the single-phase version of the QE-POWER-T, the smallest single-phase power meter which is able to manage any current sensor (1 / 5 A, 333mV, Rogowski probes). It is ready to be incorporated into monitoring and data logging systems. RS485 Modbus RTU output and configurable digital contact available (window alarm threshold). Universal input for current transformers with two versions (STD and PLUS) available to meet all measurement needs. MAIN FEATURES: -POWER SUPPLY: 10…40 V DC or 19…28 V AC – 50/60 Hz -VOLTAGE INPUT: Direct connection up to 500 V RMS max (40…70 Hz) -Configurable transformation ratio for CT and VT -OUTPUTS: RS485 Modbus RTU and SPST digital contact (< 40 V, <100mA) -AVAILABLE MEASUREMENTS (STD and PLUS): Irms, Vrms, Ipk, Vpk -Active power (W) -Reactive power (VAR) -Apparent power (VA) -Frequency -Power factor (inductive/capacitive) -Energy (kWh) -Bidirectional energy (kWh), positive and negative -Active and reactive energy (kVARh), inductive/capacitive -Crest factor -Tanφ per phase and average (inductive/capacitive) -Power factor average -Power factor distortion (inductive/capacitive) and average -THD (V, I ) -Min, average and max power measurements -Max demand over 15 minutes -Time of max demand (monthly) (month, day, hour, minutes) -Time above a threshold.
