Hospital Isolated Power Supply

The medical IT system is mainly used in medical locations such as operating room, ICU/CCU intensive care unit, providing safe, reliable and continuous power distribution for the important equipment at these locations.

The products can realize the real-time monitoring of insulation, load and temperature of isolation transformer in IT system, and have the functions of system insulation fault loop positioning and centralized monitoring by multiple pieces of systems. 

Products are certificated with IEC 61326,IEC61557,IEC61000 and CE by TUV.

Product Fuctions

AITR series medical isolation transformer

Ratio between the primary and secondary windings is 1:1;

It is with PT100 temperature sensor monitoring temperature of isolation transformer;

Used for transformation of TN system into IT system (ungrounded system) after isolation transformer;

AIM-M200 medical insulation monitoring device

Real-time monitoring and fault alarm of ground insulation resistance, transformer load current and transformer winding temperature of the monitored IT system

Used together with insulation fault locator,it can remotely locate fault and display fault locations

Real-time monitor disconnection fault, temperature sensor disconnection fault and the functional grounding disconnection fault in monitored system, and alarm within 2s after when the fault occurs

2 field-bus communication technologies are used to commnicate with remote alarm and display indicator, test signal generator, insulation fault locator and upper computer  management software respectively and it can real time monitor IT system operation status.

With event record function,it can record alarm occurrence time and fault type

ASG150 test signal generator

Data can be exchanged with other device by CAN BUS communication

With fault locator,it can generate fault location signal to the system when fault occurs in the IT system

When L1 or L2 is disconnected, it can be indicated by LED

AIL150-4 or AIL150-8 insulation fault locator

Data can be exchanged with other device by CAN BUS communication

With ASG150 test signal generator,it can realize fault locating function.AIL150-4 can locate up to 4 circuits insulation fault locations and AIL150-8 can locate up to 8 circuits insulation fault locations.Positioning circuit is indicated by LED.

AID150 remote centralized alarm indicator

It can remotely monitor operation status of up to 16 systems and it can display whether the access system communication is intact

It can remotely set alarm value of insulation resistance,load current and transformer temperature.And it can remotely start self-check of insulation monitor device

When insulation failure,overload,transformer excessive temperature rise or wiring faults occur in any of monitored systems,it can alarm by sound and sound can be eliminated manually

With events record function,it is convenient for the operator to analyse system operation status and eliminate faults timely,and up to 20 latest records can be saved.
