The WM40-96 Smart Modular Power Analyzer has an application adaptive display and allows up to 16 freely configurable virtual alarms with OR/AND logic.
A recent energy meter provides a way to measure electrical variables — current, voltage, power, energy, and harmonics. – in applications that demand accurate parameters analysis, control, data stamping, and retransmission. The WM40-96 Smart Modular Power Analyzer comes in a streamlined modular basic unit and plug in modules, so it can be used in almost any application. What’s more, this compact modular power analyzer uses little space in the back side of control doors and switchgears.
The smart power analyzer has an advanced keypad and display that includes five rows of measurements and bar-graph, power-demand indicator. An optional front optical-communication port makes for quick access to measurements and easy programming. Optional hardware expansion modules include serial, Ethernet, and BACNet communication with or without onboard storage for data logging, digital inputs, static, relay and analog outputs. The unit is also capable of temperature and process signal measurements. Tech specs include:
