General

AIL150-4/AIL150-8 insulation fault locator uses high-precision signal detection circuit with high sensitivity transformer. It detects ASG150 test signal generator' s signal which is injected into the system. It can accurately locate the insulation fault circuit. Among them, AIL150-4 insulation fault locator can locate insulation faults of four loops, AIL150-8 insulation fault locator can locate insulation faults of eight loops.


Function

* Insulation fault location in medical IT systems.
* 4 or 8 channels with measuring current transformer per AIL150.
* Up to 16 measuring channels can be combined by can bus in one medical IT system.
* Aresponse time of up to 2 s in medical IT system acc. to IEC61557-9.
