The AIM-T500 is a high-performance insulation monitoring device designed for continuous, real-time monitoring of ungrounded (IT) power systems. With multiple monitoring functions including insulation resistance, temperature, voltage, leakage current, and alarm history, the AIM-T500 provides early detection and comprehensive diagnostics to prevent electrical accidents. It features a clear LCD display, relay alarm outputs, and RS485 communication for centralized data logging and remote alerts. Ideal for use in hospitals, railways, substations, and petrochemical industries, it ensures electrical safety and system stability under critical operational conditions.
