The power analyzer APM/2D can measure 24 electrical variables simultaneously on all types of networks (single or three-phase with three or four wires) and with any type of load (balanced or unbalanced). Yhe TRMS measurements taken (V, I, cos-fi, kW, kVAr, kWh, kVArh) are shown in succession on a highly legible back-light LCD display, with the possibility of manual or automatic scanning between totals or system data and partial or phase data.
With the optional RS485 interface, APM/2D can also transfer the measurements to a supervision and control system, using the market standard Modbus as the communication protocol. A programmable pulse output provides the capability of totalising the energy consumed externally on a pulse counter or a PLC. The operating parameters like, for example, the type of system, the ratio of the step-down transformers or the intervals between automatic scanning of measurements are easily programmed by means of a procedure protected by password.
