V-TAC Meter DFUN Three Phase Bidirectional Counter 3*230V/400V RS485 for Accurate Measurement and Advanced Energy Control

V-TAC SKU 11513 is a 3-phase smart meter produced by DFUN , used to measure energy consumption in low voltage AC systems (110V, 120V, 220V, 230V, 240V AC). The device features a 7+1 digit LCD display (999999.9 kWh) and two LEDs indicating pulse output (settable for kWh or kvarh). It can measure voltage, current, active power, reactive power, apparent power, power factor, frequency, active energy, reactive energy and multi-tariff energy value.

The device has a rated current of 5(63)A with Class 1.0 accuracy and 5(6)A with Class 0.5s accuracy. It is designed to operate efficiently and safely, and can tolerate current spikes of up to 63A for short periods of time. This can be useful in situations where there are brief increases in power consumption, such as switching on a large appliance.

The DFPM93 three-phase meter can be easily installed on a DIN rail and is suitable for house construction, commercial buildings, switchboard rooms, power distribution boxes, etc. It is equipped with an RS485 communication interface with MODBUS or DL/T 645 protocol (selectable). It has 3 keys for programming and is mounted on a 35mm DIN rail , in compliance with the DIN ED5002 standard.

The 3-phase smart meter has advanced functions, including freezing energy recording for every 15 minutes/day, support overvoltage timing, undervoltage timing, overload timing, and LCD display recall for phase sequence error. In addition, it records historical energy for the last 31 days and last 12 months.

The meter can operate in an operating temperature range of -20°C to 55°C, with a storage temperature of -25°C to 70°C. The permissible humidity is 5% to 95%, non-condensing. The device weighs 200 grams.
