V-TAC Meter DFUN Single Phase Bidirectional Meter 1*230V RS485 for Accurate Measurement and Advanced Energy Control

V-TAC SKU 11511 is a single 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 6+1 digit LCD display (999999.9 kWh) and a LED indicating pulse output. It can measure voltage, current, active power, reactive power, apparent power, power factor, active energy and reactive energy.

The device has a rated current of 5(63)A , so it is designed to operate efficiently and safely with a current of 5A , but also has the ability to tolerate current spikes of up to 63A for short periods of time. This can be useful in situations where there are short bursts of power consumption, such as switching on a large appliance.

The meter has a compact size of 100x36x65mm (2 modules) and can be mounted on a 35mm DIN rail , in accordance with the DIN ED5002 standard. It is equipped with an RS485 communication interface with MODBUS-RTU or DL/T 645 protocol (selectable) and a baud rate of 2400, 4800 or 9600 bps (default). The device address can be set between 1 and 247.

The smart meter features anti-crawl design, password protection, and two buttons: one for page up/down navigation and one for programming. The device power supply is 2W, with an operating frequency of 50Hz or 60Hz (optional) and a nominal voltage of 230Vph-N or 110Vph-N (optional). The energy measurement accuracy is Class 1.0 .

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.
