MAVOWATT® 50 Energy and Power Disturbance Analyzer
■Eight Mutually Isolated Measurement Inputs
▲The MAVOWATT 50 is equipped with | eight isolated measuring circuits (4 each for voltage and current) for simultaneous measurement of phase and neutral conductor voltage and current. By connecting a suitable measuring transducer, the fourth channel can be used alternatively for acquiring other physical quantities, e g. the temperature of a motor or transformer, or wind speed at a wind power turbine. Mutual isolation of the measuring channels provides for enhanced operating safety and prevents circulating currents, or allows for simultaneous measurement in two separate electrical circuits, e g. at the input and the output of a rectifier.
◆Four analog voltage measurement inputs, namely Uli, Uu, Ul3 and Ul4, for direct or alternating voltages of up to 900 V @ measuring category III or 600V@CAT IV. Measurements in medium-voltage systems can be performed by means of voltage transformers at the system side Their transformation ratios can be set individually for each input.
◆Four analog current measurement inputs, namely In, Il2, lu and Il4, laid out as voltage inputs (see Technical Data for measuring ranges) for connecting shunts or (clip-on) current transformers with voltage output. If flexible current sensors are utilized (Rogowski coils), a 9 V voltage output can be used to supply them with power. The transformation ratio can be set individually for each input.
■Eight Digital Status and Control Inputs
▲Four binary status inputs, namely a, b, c and d. for displaying and recording ON/OFF statuses, for example the operating states of machines, equipment and alarm devices. The inputs are equipped with a common floating reference point, and are S〇 compatible (max. 30 V).
▲Four binary control inputs, namely e, f, g and h. for controlling device functions, for example starting / stopping recordings. These are also floating inputs, and are TTL compatible.
