APM series power meters of ACREL are ac digital multifunction meters that are designed according to IEC standards and synchronized with international advanced technology. APM series three phase energy meters have full power measurement, energy statistics, analysis of power quality and network communications and other functions, and 3 phase digital energy meters are mainly used for comprehensive monitoring of the quality of power supply network.
This series of 3 phase energy meter use a modular design, with a rich function of the external DI / DO module, AI / AO module, event recording (SOE) module with T-Flash (TF) card, network communication module, temperature and humidity measurement module, can achieve full power measurement of electrical circuit and monitoring of switch status, dual RS485 with Ethernet interface can realize data copying of RS485 master station, eliminating the need for data switching exchange. PROFIBUS-DP interface can realize high-speed data transmission and networking function. Acrel can provide multifunction meter with rs485 in good price.
