Insulation monitor, AC networks AAL-2
The AAL-2 is used to supervise insulation resistance between an isolated AC voltage distribution network and an earth/safety cable.
The insulation monitor is applicable with single-phase and 3-phase networks with/without neutral for voltages up to 440 V AC.
The AAL-2 has a built-in relay output and an adjustable warning set point.
- Insulation monitoring of AC networks of up to 440 V AC
- 10 M or 1 M ranges
- Adjustable warning set point
- Delay to prevent unwanted warnings
