💡 Product Description

Three-phase Insulation Monitoring Device for Isolated Power Supply

Insulation Monitoring Device

The medical isolation power supply cabinet is a power distribution cabinet with a local IT system designed for the power supply requirements of medical Class 2 places. The IT system is equipped with an insulation monitoring device to monitor the insulation status of the system.

Each output circuit adopts a circuit breaker with short-circuit protection function; other system output circuits use circuit breakers with leakage protection function. Products include GGF-O series for operating rooms and GGF-I series for ICU/CCU, ensuring compliance with IEC60364-10:2002 standards for power safety and reliability.

Facility Overview
Frequently Asked Questions
What is a medical IT system?
A medical IT system is an ungrounded power distribution system designed for Class 2 medical locations. It ensures that a single insulation fault does not cause the power to trip, maintaining continuous operation of life-support equipment.
Why is insulation monitoring required in operating rooms?
It provides real-time detection of insulation degradation between the power system and the ground. This prevents electric shocks to patients and staff and avoids unexpected power failures during critical surgeries.
What parameters can the AIM-M100 monitor?
It monitors ground insulation resistance, transformer load current, and transformer winding temperature, providing early warning alarms via relay outputs.
Does the system support remote monitoring?
Yes, the device features an RS485 interface with Modbus-RTU protocol support, allowing it to connect to remote annunciators like the AID150 or central monitoring software.
What is the difference between GGF-O and GGF-I series?
The GGF-O series is specifically tailored for operating rooms, while the GGF-I series is optimized for ICU/CCU environments, both ensuring compliance with IEC standards.
Is the enclosure protected against dust and moisture?
Yes, the systems offer protection levels of IP31 or IP34D, making them suitable for the controlled environments of modern medical facilities.
