Product details






1. Product Overview:
Intelligent single phase digital ammeter tunes CT parameters and PT parameters through panel key, and display a running system visually, a row of 4 bits LED display single phase value clearly, It can replace traditional analog pointer meter. What is more, with RS485 interface, it is convenient for data exchange with microcomputer, PLC, etc. It is a kind of high-performance automatic meter which is suitable for industrial and mining enterprises, civil construction, building automation and some other modern distribution system.
And this kind of product has optional Configurations of RS485 communication interface (optical coupling isolation), Mod Bus RTU communication protocol, 1-3 road programmable analog output (C4-20mA DC0-20mA), and 1 road ad relay alarm upper and lower output.
Product fictures:
Adopting industrial grade DSP of high reliability. Data acquisition speed is fast, metering accuracy is high and processing speed is fast.
With powerful data acquisition and processing functions, they can achieve the metering of all electric parameters.
Small size and easy installation. They adopt self-locking panel installation structure and can be installed without the need of screw fixation.
Convenient and flexible wiring. They are commonly used in three-phase three-wire system and three-phase four-wire system meters.
With RS-485 digital interface, they adopt standard MODBUS-RTU protocol.
One channel of alarm output is optional for bound monitoring on the metered parameters.
One-channel analog output is available. Three-channel analog output is optional for three-phase current and voltage. The metered transmitting output can be selected and the output is DC4 ~ 20mA, DC0-5V. 0~12~20mA, etc. are optional
Real-time display with four digits of LED digital. The display value of the meter can be set through the panel buttons.
Standard CT input, standard PT input or direct input
