NHR-3900 series power quality analysis and recorder is an analysis and recorder that integrates voltage/current true RMS measurement, power quality analysis, power demand analysis, harmonic analysis, and power analysis.
Apply digital sampling technology to measure AC current/voltage, active power, reactive power, apparent power, power factor, power frequency cycle, harmonics, active energy, reactive energy, four-quadrant energy, and peaks in three-phase electrical lines.
Real-time measurement and display, record analysis and control of coefficient and unbalance degree, etc.
, diversified communication methods, and centralized management of data can be realized by networking
.
NHR-3900 series power quality analysis recorder adopts new integrated circuit and digital sampling technology.
The analyzer adopts 3.
5-inch 320*240 dot matrix TFT high-brightness color graphic liquid crystal display, LED backlight, clear picture and wide viewing angle
.
This machine has the functions of analog output, communication output and cumulative pulse output, supports RS232/485 communication interface, Ethernet interface, micro printer interface and USB interface, Micro SD card, supports dry contact digital signal input, powerful functions and high cost performance
.
Products are widely used in distributed power monitoring systems, substation integrated automation systems, unattended substations, low-voltage intelligent power distribution systems, intelligent switchgear/distribution panels, intelligent box-type transformers and data acquisition of building automation systems
.
The main product features of NHR-3900 series power quality analysis recorder: •Support USB data backup and SD card memory expansion, and use with data management software to realize data query and analysis
.
•For measurement and metering functions, it is equipped with 2 groups of energy accumulative pulse output and various communication interfaces; the communication interface adopts RS485 or RS232 interface of MODBUS RTU protocol and Ethernet interface of MODBUS TCP/IP protocol
.
•4-channel digital input, 4-channel analog output, 2-channel relay alarm output to achieve powerful data remote transmission and control functions
.
• The software has its own rate setting, which can display the billing value of peak, peak, flat and valley
.
• Using high-performance ARM microprocessor as the core, the product has the characteristics of low power consumption, fast response, strong function and high cost performance
.
• The overall appearance is streamlined, with 96*96 and 120*120 dimensions available
.
Touch the silicone button to operate, the man-machine operation effect is good
.
•Isolation between input-output-power supply, adopt reliable protection and anti-interference design for input, output and power supply
