描述

A82-10100 is a true RMS AC current metering transformer designed to convert AC current inputs into standardized DC current outputs for easy integration with PLCs and monitoring relays. The device features a 0–20 mADC source output with ±2% tolerance at 50 Hz, operating across a current range of 0–100 AAC with a maximum continuous rating of 600 AAC and overload capability of 3000 AAC for 30 seconds. It provides 1000 VAC rms rated insulation voltage between input and output, dielectric strength of 6 kVAC rms, and impulse withstand voltage of 12 kV (1.2/50 µs), ensuring robust isolation and safety in industrial environments. The transformer operates with a power supply range of 10–40 VDC, frequency range of 40 Hz to 1 kHz, and temperature variation of ±400 ppm/°C, with a reaction time under 200 ms. This device is ideal for current monitoring applications in industrial automation, energy management systems, and protective relay schemes where accurate AC current measurement and PLC connectivity are required.
