The meter is equiped with standard 4G SD card while saving the data of electrical parameter, energy, event, SOE, alarm. Also, the setting of storage interval could be changed. (1 min interval for electrical parameter and 1 hour interval for energy)
Our users can select 3 of the optional modules at will even repeatly except for communication module. Also, the order of module installation could be random.
Except for wave record and SD card storage function, 0.2S measuring accuracy can also be a option. Besides, APM8xx can serve as reverse display meter (which means 3-phase electrical parameters measuring plus 8-channel reverse display) Also, users can measure the data through browser by using Ethernet auto WEB.
AC/DC 85~265V or 115~415V is both optional. Also, 380V line voltage can also serve as power supply.
