The active power transducer WMU350 is used for 3 or 4-conductor measuring or monitoring of power in power supply units, emergency power supplies and interconnected networks. The output of the power is +/-20mA (+/-10V) or 4-20mA (2-10V). The internal measuring is done by three 4-quadrant multiplicators, with that the reverse power (negative output) will be exactly monitoring and in case of sigal harmonics always the real power will be output. To lower the storekeeping the customer can change the maximum power value ( i.e. 3000W ) by himself below a flap of the housing.

The power values measured are output at the +/- 20mA (PMU150) / 4-20mA (PMU154) output. Measurement and evaluation are carried out via a 4-quadrant multiplier, so the correct active power is indicated in each case, even if there is distortion of the currents and voltages fed in.

Rapid Frequency Measuring Transducer FMU100 40 - 70 Hz

	• Three-way separation (input-output-auxiliary voltage) • Digital transducing with microcontroller • Input 100 - 264VAC, auxiliary voltage 11 - 33VDC • Output 0 - 20 mA or 0 - 10 V • Accuracy class 0,2 • Updating of the output value every 20 ms
Download data sheets (.PDF) FMU100 / 100-264VAC 40-70Hz	This unit is used for the rapid recording of the frequency in AC networks and for analog output as a 0-20mA or 0-10V signal. The 3-way separation allows the unit to be operated at different potentials / reduces possible disturbances between measuring and output circuit. The supply is with 11 - 33VDC. Due to the low self-heating, the transducer can be used up to an environmental temperature of 55°C.

AC Current Transducer (True RMS)AMU150

	• Three-way separation (input-output-auxiliary voltage) • Input AC Current 1A or 5A • Output 0/4-20mA, 0/2-10V simultaneous • Accuracy 1.0%, Auxiliary voltage 11 - 33VDC
