A82-20250

Current Sense Transformers Overview

The Carlo Gavazzi A82-20250 is a single-phase industrial current transformer designed for AC current measurement. It features a primary current rating of 250 A and provides a built-in 4-20 mA transducer output for direct integration with control systems. The device supports True RMS AC current conversion, ensuring accurate readings across a frequency range of 40 Hz to 1 kHz. Designed for panel mounting, it operates within a temperature range of -20 °C to +50 °C. The unit weighs approximately 0.24 kg and utilizes wire leads for connection.

Current Sense Transformers Feature Summary

• Integrates a 4-20 mA transducer output directly into the current transformer assembly
• Provides True RMS AC current conversion for high accuracy
• Supports wide frequency operation from 40 Hz to 1 kHz

Current Sense Transformers Applications

• Industrial automation monitoring systems
• Electrical energy management and power analysis
• Integration with PLCs or data acquisition systems via 4-20 mA signals

Current Sense Transformers Procurement Notes

Verify that the required primary current does not exceed 250 A and that the load circuit accepts a 4-20 mA input signal. Confirm panel mounting compatibility and operating temperature requirements fall within the specified -20 °C to +50 °C range. Ensure the application frequency is between 40 Hz and 1 kHz. Cross-reference the datasheet for terminal wiring details and burden resistance specifications to guarantee signal integrity.

Current Sense Transformers Selection Notes

Select this model when a combined current sensing and signal transmission solution is needed for single-phase AC circuits up to 250 A. It is suitable for applications requiring isolated measurement with standard industrial analog outputs. Consider the physical dimensions and weight constraints for panel installation. Compare with other A82 series variants if different primary ratings or output types are required.

Current Sense Transformers Part Context

The A82-20250 belongs to the Carlo Gavazzi A82 series of industrial current transformers. This series is characterized by integrated signal conditioning, allowing direct interfacing with control equipment without external transmitters. The component serves as a bridge between high-current electrical lines and low-current control signals in industrial environments.

Current Sense Transformers Replacement Considerations

The A82-20250 is functionally similar to the A82-2050, which shares the same 4-20 mA output architecture but differs in primary current rating (50 A vs 250 A). Verify that the higher capacity of the A82-20250 does not compromise precision at lower load currents if substituting downwards.
