This is a very comprehensive datasheet for the M-System KURE transducer. Here's a summary, broken down by sections and key takeaways:

1. General Description & Applications (Implied)

️· Function: The KURE transducer is designed to measure reactive power (likely from voltage and current inputs) and provide an output signal (DC voltage or current) proportional to this measurement. It seems geared toward power factor monitoring, reactive power measurement, and related applications in industrial settings.
️· Flexibility: The transducer supports both "Negative in lag, positive in lead" and "Negative in lead, positive in lag" measurement configurations.

2. Technical Specifications (Key Numbers)

️· Input:
- 3-Phase, 4-Wire System
- Accepts CTs and Uts for input signals
️· Output:
- DC Current (0-20mA) – Minimum Span: 1mA, Offset: Max. 1.5x span
- DC Voltage (-10 to +12V) – Minimum Span: 5mV, Offset: Max. 1.5x span
️· Power Consumption (Auxiliary):
- AC: 2 VA (rating -15/+10%, 50/60Hz)

️· Powering: The transducer *can* be powered from the input voltage under stable conditions.
️· Ripple: Output ripple increases with differences in input and power supply frequencies.
️· Mounting: Can be surface mounted or DIN rail mounted; allows for close unit spacing.

4. Connection Diagram & Terminal Assignments

️· Standard 3-Phase Connections: Clearly shows input (CTs, Uts) and output connections.
️· Terminal Details: Provides the terminal assignment for easy and correct wiring.

5. Dimensions:

️· Provides the dimensions of the transducer for physical installation.

Important Notes:

️· Configuration Flexibility: Understanding "Negative in lag/lead" is critical to correct interpretation of the output.
️· Safety: The impulse withstand voltage and insulation resistance specifications are important for safety in electrical environments.
️· Proper Wiring: Double-check all terminal assignments before powering up the transducer.
