Product details

Main feature：

●AC sampling function: The measurement and control management terminal has an AC sampling module, which can collect and calculate three-phase voltage, current, power, demand, active and reactive power, etc.

●Meter reading function: read the positive and negative active power, four-quadrant reactive power, voltage, current, active power and reactive power of the electric energy meter, freeze the power, etc.

●Control function: Powerful load control function, which can perform power control, electronic control and other over-predetermined load and peak avoidance control for users. The terminal provides four-wheel control and four remote signaling interfaces.

●Data reading and storage function: The terminal can read and store different data.

●Power consumption abnormality detection and alarm function: The terminal monitors the power measurement and control in real time, and supports abnormal alarms for the status of the meter, terminal status, metering loop status and various processing and analysis.

●Communication function: The communication between the terminal and the main station supports the "Data Transmission Protocol of Power Load Management System-2004", supports GPRS/CDMA, and has a local maintenance interface.

●Clock management: The clock error is £0.12S/h, and the clock is maintained for more than 10 years.

●Remote upgrade: The terminal supports the remote online upgrade function.

The main technical parameters：

1、Power supply: Power supply mode: Rated voltage: 220/380V, can work normally within the range of ±20% deviation. Frequency: 50Hz, can work normally within the range of deviation -6% to +2%.

2、Power consumption:

（1）In the non-communication state, the three-phase power supply terminal, the active power of each phase is not more than 5W, and the apparent power consumption is not more than 10VA.

（2）The power consumption of the current input circuit is less than or equal to 0.25VA (single-phase); the power consumption of the voltage input circuit is less than or equal to 0.5VA (single-phase).

3、Adopt built-in hardware clock circuit with temperature compensation function; in the temperature range of -25～+60℃: clock accuracy ≤ ±1s/d; under reference temperature (23℃), clock accuracy ≤ ±0.5s /d.

4、RS232 interface: 1 standard RS232 interface with a communication rate of 4800bps, which can be used for on-site communication and management.
