The active power transducer WMU350 is used for 3 or 4conductor measuring or monitoring of power in power supply units, emergency power supplies and interconnected networks. The output of the power is +/20mA (+/10V) or 420mA (210V). The internal measuring is done by three 4quadrant 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.

This unit is used for the recording and onephase measuring of active power of consumers connected in mains and generator systems. The power values measured are output at the +/ 20mA (PMU150) / 420mA (PMU154) output. Measurement and evaluation are carried out via a 4quadrant multiplier, so the correct active power is indicated in each case, even if there is distortion of the currents and voltages fed in.

This unit is used for the rapid recording of the frequency in AC networks and for analog output as a 020mA or 010V signal. The 3way 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 selfheating, the transducer can be used up to an environmental temperature of 55°C.

DC measuring transducer PDM500 calculates the real power of a DC voltage source, i.e. of a solar cell plant and transduces the voltage and current values into impulses / kWh to its output. The pulses will be counted and calculated by succesive units. The current value will be taken from a suitable power shunt resistor with a rated voltage of 60mV. The maximum voltage range is 500V, but will be reduced to the customers specification to achieve maximal possible accuracy.

The PDM measuring transducer records the power of a DC power supply and sends the value measured to the optocoupler output with potential separation in the form of pulses per kWh. Normal output pulse values are 1000 or 10,000 pulses per kWh. The voltage input receives the measuring and supply voltage, whereas the current input receives the maximum measuring voltage of 60mV from a shunt resistor. Current and voltage are at one and the same potential here. Depending on the shunt resistor used, any desired currents can be measured. Maximum current, calibrating voltage and pulse rate are required for calibrating the unit.
