Medical Isolated Power Supply Systems for Hospitals — Monitoring, fault detection & IEC standards
A medical IT system isolates the supply and monitors insulation in operating theatres, ICU and emergency areas — so faults are found before they interrupt care.
Why a medical IT system
Group 2 medical locations — continuity is a patient-safety matter.A medical IT system is an unearthed distribution arrangement used in designated medical locations, combining an isolating transformer with insulation monitoring to keep power running after a first insulation fault and to limit leakage and touch current.
No interruption on first fault
Power stays on after an insulation fault; staff fix it on a planned schedule.
Leakage current limited
The isolating transformer keeps leakage and touch current within safe limits.
Fault found early
Monitoring + fault locator pinpoints the branch, so teams act on evidence.
System architecture
One continuous system, transformer to nurse station.
Isolating transformer
AITR decouples and limits leakage.
Insulation monitor
AIM — resistance · load · temp.
Fault locator
AIL — pinpoints the faulted branch.
Products — every component of a compliant system
Devices and tables, all to IEC 60364-7-710.
