Verified Safety Design Solution
Insulation Detection
Many times,you are unsure whether the insulation monitoring
device you purchased is functional or whether the IT isolated
power supply system is operating normally,yet you have no way to verify t.We have ntegrated a test circuit internally;simply
connect it to easily confirm that the system is working safely,cor- rectly,and effectively,giving you full confidence.
Grounding System
In the clean operating room isolated power supply system, the primary and secondary sides of the isolation transform- er adopt different grounding systems:the primary side uses the TNS or TT system,and the outgoing circuit employs an A-type residual current operated protective device;the sec- ondary side adopts the IT system.For ICU/CCU ward isolat- ed power supply systems,only the IT system is used.
Audible and Visual Alarm
The IT system outputs the following signals to the audible and
visual alarm indicator:”IT System Operating”signal,”Insulation Monitoring Alarm”light signal,”Insulation Monitoring Alarm”audi- ble signal,”Transformer Overload Alarm”signal,”Transformer
Over-temperature Alarm”signal,and transformer load indicator value.It also collects the buzzer mute signal simultaneously.
Incoming Power Mode
The clean operating room isolated power supply system is configured with two selectable incoming power modes:
single incoming power and dual incoming power automatic switching mode.The automatic switching time for dual in- coming power is less than 0.3 seconds.

DM08-CX Medical IT Insulation Monitor
Test
Many times,you may be unsure whether the insulation monitor you
purchased is functional or whether the T isolated power supply system is operating normally,and feel frustrated that you cannot verify it.We have integrated a test circuit internally.With a simple connection,
you can confirm whether the system is working safely,correctly, and effectively with confidence.
Functions
In the IT circuit isolated by the medical transformer,when the insulation resistance to ground is generated by equipment or other means,the
isolated circuit will not form a loop.At this time,an insulation monitor must be installed to monitor in real time whether the isolated circuit has a fault,issue an alarm,and link with other safety devices.
High Performance
Military-grade components are the foundation for ensuring trouble-free operation.With optimized circuit design,all products have undergone tests such as voltage withstand,high and low temperature,aging,and impact drop simulation,fully complying with medical safety standards.
Safety
It will not affect the power supply under any extreme conditions.
The circuit and housing are filled and manufactured with fre-resistant materials,and all ports are designed with double protection circuits.
New Technology
It uses the most advanced measurement technology in the industry,
which will not generate ripple and interference in any medical equipment. Different from the currently commonly used voltage return measurement method,only two companies in the world master this technology,and
Deweimin is one of them.
