Application of Acrel Medical IT Cabinets in Hospitals in Indonesia

1.Project Overview

Modern diagnosis and treatment, almost the most advanced medical equipment in various medical fields. With the widespread application of electronic devices, the threat to the lives of current patients is also increasing. Especially those that are critical, such as operating room and type 2 operating room, various patients in operating room or rest state, and other medical rooms, the sensor has some special people in the ICU, the tiny ward leakage current may cause the patient electrocuted. When the system suddenly loses power (such as baby ward, operating room or in the consultation room, childbirth ward), when the catheter patient of various health or treatment equipment suffers from the body, the threshold value of the somatosensory sensation is reduced to 10 microamps.

Acrel's medical monitoring isolation cabinet is equipped for the power supply demand of the system location. The power supply has the power distribution cabinet monitoring of the IT system, and the isolation cabinet equipment of the IT equipment monitors the isolation of the system. Hybrid protocol and hybrid chamber protocol.

Use the security management equipment to monitor the data display of the operating room and IT equipment control cabinet. Patient safety, real-time monitoring and visual management of premises.

Product name and type	Product picture	Description
AITR series medical isolation transformer		AITR series isolation transformer is specially used in medical IT system. The windings are treated with double insulation and have electrostatic shielding layer, which reduces electromagnetic interference between windings. The PT100 temperature sensor is installed in the wire bag to monitor the temperature of transformer. The whole body is treated with vacuum invasion paint, which increases mechanical strength and corrosion resistance. The product has good temperature rise performance and very low noise.
AIM-M200 medical intelligent insulation monitor		AIM-M200 medical intelligent insulation monitoring instrument adopts advanced microcontroller technology, which has high integration, compact size, convenient installation and integrates intelligence, digitalization and networking in one. It is ideal selection for insulation monitoring of isolation power system in Class 2 medical locations such as operating room and intensive care unit.
AKH-0.66P26 current transformer		The AKH-0.66P26 type current transformer is the protective current transformer supporting the AIM-M200 insulation monitor, of which the maximum measurable current is 60A and the transformation ratio is 2000:1. The current transformer is directly fixed inside cabinet by screwing, and the secondary side is leaded out by the terminal, which is convenient to install and use.
AIL150-4/AIL150-8 insulation fault locator		AIL150-4/AIL150-8 insulation fault locator adopts high sensitivity transformer combined with high precision signal detecting circuit, which detects the signal imported into the system from ASG150 test signal generator and accurately locates the circuits which have insulation faults. AIL150-4 insulation fault locator can locate the insulation faults of 4 circuits, and the AIL150-8 insulation fault locator can locate the insulation faults of 8 circuits.
AIL150-4/AIL150-8 insulation fault locator
ASG150 test signal generator		The ASG150 test signal generator adopts 32-bit microprocessor chip and high-precision signal generation circuit to realize the generation of specific test signal. When the monitored IT system has insulation faults, it can start up and produce test signal in time, working with the insulation fault locator to realize insulation fault location.。
HDR-60-24 power module		HDR-60-24 direct-current power supply can provide 24V DC power supply simultaneously for AIM-M200 medical intelligent insulation monitoring instrument, ASG150 test signal generator, AIL150 series insulation fault locator and AID150 centralized alarm and display instrument. The power supply is of high capacity, stable voltage output and convenient installation, which can meet the power-supply requirements of the above-mentioned meters and is the recommended power supply product.
AID150 centralized alarm and display instrument		AID150 centralized alarm and display instrument adopts the LCD liquid crystal display and achieves data exchange with AIM-M200 medical intelligent insulation monitoring instrument through RS485 communication interface, which can real-time monitor multi-channel data of AIM-M200 medical intelligent insulation monitoring instrument.
