+===== General description =====
+The unit measures and displays the characteristics of three phase four wires(3p4w) supplies, including voltage, frequency, current, power, active and reactive energy, imported or exported.
+ Energy is measured in terms of kWh, kVArh. Maximum demand current can be measured over preset periods of up to 60minutes.
+In order to measure energy, the unit requires voltage and current inputs in addition to the supply required to power the product.
+The requisite current input(s) are obtained via current transformers (CT).
+This power sensor can be configured to work with a wide range of CTs with 0.33V output, giving the unit a wide range of operation. Built-in interfaces provide pulse and RS485 Modbus RTU outputs. Configuration is password protected.
+This power sensor can be powered from a separate auxiliary (AC or DC) supply. Alternatively, it can be powered from the monitored supply, where appropriate.
