APM800 Three Phase Multi-Function Energy Meter

The APM series meters are suited for measuring and displaying electrical quantities of electricity networks. The accuracy of active energy measurements corresponds to class 0.5S in accordance with the requirements of IEC62053-22. The APM series meters offers many high-performance capabilities needed to meter and monitor an electrical installation in a compact 96 x 96 mm unit.All models include an RS-485 Modbus communication port, two digital input, two digital output,and alarming on critical conditions.The model of APM810 is able to perform current/voltage harmonics for assessment of the power quality. In addition the model of APM801 can offer the active energy accuracy up to class 0.2S. Expand any model with field-installable option modules that offer a choice of additional digital inputs and outputs, analogue inputs and outputs, and Ethernet port.
