The DOLD AN5892.11/800 is a high-performance insulation monitoring device designed for IT systems operating on AC, DC, or mixed voltages. Engineered to ensure safety and operational continuity, the device continuously monitors insulation resistance and triggers an integrated relay if the resistance falls below a preset threshold of 50 kΩ.

Capable of measuring insulation in systems up to 1500V DC, the AN5892.11/800 operates on a 230V AC power supply and supports a frequency range of 40–400 Hz. This makes it ideal for critical infrastructure, industrial power distribution, and medical or renewable energy systems where insulation failure can lead to safety hazards or downtime.

🔧 Key Features:

✅ Continuous insulation monitoring for AC/DC IT systems
✅ Max measurable voltage: up to 1500V DC
✅ Trip threshold: 50 kΩ (fixed)
