The M9428A is a 1-phase watt transducer that multiplies voltage and current in real-time to measure real power ("Watt"). It features a 2-pole low-pass filter, signal isolation amplifier, and outputs a bipolar current signal. The device measures unlimited current values with X:5-current transformers and can measure reactive power ("VAR") with an option. Its primary application is in industrial controls, process control computers, and programmable controllers. The transducer has a CE conformity, EMC compliance, and a 2-year warranty. Technical specifications include voltage ranges (100V, 115V, 230V, 400V), input impedance (1.56MW at 400V), and current ranges (0...1, 0...2, 0...5 AC/DC). The output options are 0...1V, 0...10V, 0...20mA, and 4...20mA, with adjustable zero and gain settings. The device has a maximum rise time of 400ms, galvanic isolation, and an accuracy of ±0.1%.
