POWER MEASURING TRANSDUCER (WATT & VAr)

POWER MEASURING TRANSDUCER (WATT & VAr)

Product catalog summary

Overview: The document details the specifications and applications of the MPxWx/MPxRx power measuring transducers, designed for precise monitoring of active (W) and reactive (VAr) power in balanced or unbalanced load systems. These transducers are ideal for systems requiring fast response and precision, such as those regulating and controlling loads on generators, motors, and inverters.

Specifications:

Precision: True RMS class 0.5 for kW and class 1 for kVAr, unaffected by waveform distortion.
Response Time: Very fast analogue output response time of less than 50 milliseconds.
Isolation: 1500V galvanic isolation.
Current Input: Compatible with 1A or 5A current transformers.
System Voltage and Auxiliary Supply: 100-120, 200-240, 380-415, or 440-460VAC at 40-70Hz; optional auxiliary voltage of 18-36 or 36-160VDC.
Analogue Output: Various configurations including -1/0/+10mA, 0-10V, and 4-20mA.
Temperature Range: Operates between -20 to +70ºC.
Protection: Front protection rated at IP54, with an optional upgrade to IP65.
Compliance: Meets IEC60092-504, IEC60068/60092, and IEC61000/60533 standards.

Applications: Suitable for use in systems that require fast response and precision monitoring of active/reactive power, particularly in the regulation and control of loads on generators, motors, and inverters.

Designations: Available in various circuit configurations including single-phase and three-phase systems, both balanced and unbalanced.

Ordering Example: An example configuration includes type MP2W3E with a 24VDC auxiliary supply, 690:230V system voltage, 1500/1A input current, and an analogue output range of -150/0/+1500kW.

Ideal for systems for regulation and control of the load on generators, motors and inverters. The MPxWxE is a high precision power transducer for balanced or unbalanced load system active (W) or reactive (VAr). The unit has ONE very fast response analogue output signal, with amplitude proportional to the measured active power (W) or reactive power (VAr) level. The noise-immune mAoutput is isolated from both the C.T. and voltage inputs and auxiliary power. Agreen "Supply On" LED indicates the auxiliary supply presence.
