General

APM series power meters of ACREL are power meters that are designed according to IEC standards and synchronized with international advanced technology. APM series meters have full power measurement, energy statistics, analysis of power quality and network communications and other functions, are mainly used for comprehensive monitoring of thequality of power supply network.

This series of meters 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, 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.

Q: What’s the storage capacity, storage format and data storage interval of SD card?

A:The meter is equiped with standard 4G SD card while saving the data of electricalparameter, energy, event, SOE, alarm. Also, the setting of storage interval could bechanged. (1 min interval for electrical parameter and 1 hour interval for energy)


Q: How should I select the expanded modules of APM8xx?

A:Our users can select 3 of the optional modules at will even repeatly except forcommunication module. Also, the order of module installation could be random.


Q: The features of APM8xx?

A:Except for wave record and SD card storage function, 0.2S measuring accuracycan also be a option. Besides, APM8xx can serve as reverse display meter (whichmeans 3-phase electrical parameters measuring plus 8-channel reverse display)Also, users can measure the data through browser by using Ethernet auto WEB.


Q: As for the auxiliary power supply of APM8xx?

A:AC/DC 85~265V or 115~415V is both optional. Also, 380V line voltage can alsoserve as power supply.
