Set.counter LE-01MQ&INTEGR wi-modbus-d

LE-01MQ is a single-phase electronic energy meter with bidirectional measurement and network parameter analysis. The device records active and reactive energy (import/export), instantaneous values (voltage, current, power, apparent power, reactive power, power factor), frequency, and maximum power demand. It is equipped with two pulse outputs and an RS-485 communication port with Modbus RTU protocol support, enabling remote reading and integration into the measurement network.

Electrical and functional parameters

• Measurement system: 1P2W – single-phase 2-wire (230 V + N).
• Reference voltage: 230 V AC (range 176–276 V AC).
• Frequency: nominally 50 Hz (accepted 50/60 Hz ±2%).
• Current: Ib = 5 A, Imax = 100 A, Imin = 0.25 A, start current 0.4% Ib.
• Active / reactive / apparent power: measurement of active (W), reactive (Var) and apparent (VA) power with an accuracy of ±1% of the maximum range (for power) and ±1% IEC 62053-21 for active energy.
• Accuracy class: class B (detailed accuracies: voltage 0.5% of max range, current 0.5% of nominal, frequency 0.2% mid-range, cosφ 1% unity).
• Energy: records imported/exported active energy and reactive energy import/export; total energy available in registers.
• Pulse outputs: 2 x OC (open collector) 27 V DC / 27 mA; output 1 programmable for kWh/kVarh with pulse constant selection (1/10/100/1000) and pulse width (60/100/200 ms); output 2 fixed for kWh (3200 pulses/kWh) with a width of 200 ms.
• Communication: RS-485 with Modbus RTU; network address 1–247; transmission speeds 1200/2400 (default)/4800/9600 bps; parity NONE/ODD/EVEN; stop bits 1/2.
