overview

Suitable for large charging stations, high-power charging piles, communication base stations, photovoltaic power generation and other occasions that require DC metering;

main features

DJSF1778-SThe dual circuit DC energy meter adopts high-performance metering chips and rich LCD displays, manufactured using advanced microelectronics technology and SMT production processes. It has the characteristics of independent dual circuit metering, high accuracy error, stable performance, rich functions, and strong anti-interference ability, which can meet the stable operation of long-term network connection;

major function

Ø It can independently measure the voltage, current, and power of two circuits, and can independently measure the positive and negative active energy of each circuit. It can be stored for up to 12 months and has power direction recognition and indication functions;

Ø Dual circuit independent design, independent operation of metering and storage, without interference with each other;

Ø The optional time division rate electricity metering function allows for the modification of time period rate parameters through parameter setting software;

Ø Equipped with LCD display, supporting commonly used voltage, current, power, battery level, and prompts;

Ø Equipped with two independent RS-485 communication interfaces that do not interfere with each other and support DL/T645-2007 or Modbus protocols;

Ø 485The default baud rate is 2400bps, which can be modified to 1200-9600 through parameter setting software;

Ø It has rich self checking, error correction, alarm and security prevention functions;
