power & energy monitoring meter
The power meter is designed for the power monitoring needs of power systems, industrial and mining enterprises, public facilities, and smart buildings. It can measure all common power parameters, such as three-phase current, voltage, reactive power, electrical degrees, etc.
Feature
Direct access to signals from current and voltage transformers
PT/CT change can be set arbitrarily
The instrument display can be scrolled and set
I/O switch quantity, relay alarm output, 4~20Ma, 0~5V, 0~20Ma analog quantity and other functional modular design
Multiple meters can be set with different addresses
It can communicate with SCADA, PLC system, and can communicate with various software in the industry (Intouch, Fix, Citec, configuration network, etc.)
LED or LCD display, high visibility
Easy installation and simple wiring
The instrument adopts a special power-loss protection circuit. In the event of a power failure, the data will not be lost. After the power is restored, the instrument will continue to run.

Functions
Kc900 power & energy monitoring meter is designed with microprocessor technology and AC sampling technology. Each meter can measure various parameters. As the front end of remote monitoring system (SCADA), it can be used in the network or alone. The network power & energy monitoring meter adopts the asynchronous half-duplex RS485 communication interface and the MODBUS-RTU communication protocol to meet your automated communication system. A single and reliable communication network can be constructed by using low-cost shielded twisted pair wiring. . No matter in weak illumination, or in the case of king power system, the high-brightness LED display will provide you with clear data display.
KC900 power & energy monitoring meter can realize high-precision four-quadrant energy measurement. The measured energy includes active energy absorption, active energy release, inductive reactive energy, and capacitive reactive energy.
