Single phase ammeter （with RS485 communication）
Brand : Zhongrui
Product origin : Yangzhou,China
Delivery time : 7-10 days
Supply capacity : good
☆ Overview
● Single phase ammeter with communication applicable to power grid, automatic control system, the main measurement of the current grid parameters, in accordance with its additional functional division, we have A, S, K, B four series of digital instrumentation.
● A series intelligent digital current instrumentation, is through direct AC sampling, and the use of true RMS algorithm for measuring current, and by digital tube (LED) or liquid crystal(LCD) directly displayed instrument directly.
● S series intelligent digital explicit ammeter is in the A series based basically increase all the way RS-485 communication interface output (using Modbus protocol) to facilitate the network of digital instrumentation.
● K series intelligent digital explicit ammeter is in the A series basically increase of 2-way relay alarm output function (to achieve the upper and lower alarm).
● B series intelligent digital explicit ammeter is in the A series basically increase to increase the 4-20mA analog output transmission function.
