Product Parameters

Performance characteristics

The device has compact structure, sealed chassis, maintenance-free design, good anti-interference performance, and is suitable for poor operating environment.

 

 

Technical parameters

1. Using the international popular high-speed processor, the main frequency is 200 MHz, the built-in resources are rich, the peripheral circuit design is simple, and the manufacturing quality and stability of the product are guaranteed. Sufficient hardware resources, 8M bytes of Flash Memory memory.

2. Measure three-phase current and zero-sequence current (Ia,Ib,Ic,Io), three-phase or line voltage (Uan,Ubn,Ucn,Uab,Ubc,Uca), active power P, reactive power Q, power factor cosφ, frequency f, active power kWh, reactive power kVarh.

3. The measured values of current, voltage, power and electric degree not only reflect the fundamental wave, but also correctly reflect the 2~13 harmonics, and the frequency is 45~60HZ adaptive, so that the measurement results are consistent with the special measuring meter.

4. It has a 4 ~ 20mA DC analog output (which can be customized as current, voltage or power) to replace the AC acquisition transmitter.

5. Up to 15 users can customize the name of the open interface.

6. The export mode of the protection element can be set through the trip matrix to facilitate the user to select the relay to be operated. All relay outlet contacts can be selected as trip contacts (automatic return) or signal contacts (return after reset).

7. With its own operation circuit, it can adapt to 0.5A ~ 5A switch tripping current, and the operation circuit is common to AC and DC.

8.GPS timing can be based on network timing, and B code timing (RS485 interface) is also supported.

9. Differential protection has a criterion to prevent TA saturation from causing misoperation of differential protection when equipment is started or out-of-zone fault.

10. Effective and reliable TV disconnection criterion, effectively prevent the motor low voltage components malfunction.

11. Two 100M Ethernet communication interfaces, one RS485 communication interface, support IEC60870-5-103,Modbus and other protocols.

There are 12.16 fault records, and the sampling point record contains up to 13 analog quantities (interval is 1mS), and the record adopts standard Comtrade format.

13. The static power consumption of the whole machine is low (about 6W), and the liquid crystal module adopts new technology, which greatly improves the service life.

14. High anti-interference performance, through 10 electromagnetic compatibility testing certification, fast transient, electrostatic discharge, surge anti-interference performance has reached the highest level (level IV) standards.

15. Working environment temperature range:-25 ℃ ~ +55 ℃ (liquid crystal without fuzzy, slow phenomenon).
