??DJSF1352-RN Series DC Energy Meters

??DJSF1352-RN系列直流電能表是針對(duì)直流屏、太陽(yáng)能供電、電信基站、充電樁等應(yīng)用場(chǎng)合而設(shè)計(jì)的，該系列儀表可測(cè)量直流系統(tǒng)中的電壓、電流、功率、正向與反向電能。既可用于本地顯示，又能與工控設(shè)備、計(jì)算機(jī)連接，組成測(cè)控系統(tǒng)。同時(shí)它具有多種外圍接口功能可供用戶選擇：帶有RS-485通訊接口，采用Modbus-RTU協(xié)議；可帶繼電器報(bào)警輸出、開關(guān)量輸入/輸出。根據(jù)不同要求，通過儀表面板按鍵，對(duì)變比、通訊進(jìn)行設(shè)置與控制。

??DJSF1352-RN series intelligent DC energy meter is designed for applications such as DC panels, solar power,telecommunications base stations, and charging posts. This series of instruments can measure voltage, current, power,forward and reverse power in DC system. It can be used for local display, and connected with industrial control

??equipment, computers, form a measurement and control system. And it has a variety of external excuse functions for the user to choose: RS485 communication interface, Modbus-RTU protocol, relay alarm output, digital input/output. According to different requirements, through the instrument panel keys, you can set the ratio, communication parameters.
