Medical IT Isolation Power System

In critical healthcare environments such as Operating Theaters (OT) and Intensive Care Units (ICU), power continuity is not just a technical requirement—it is a life-critical necessity. The YCIT Series Medical IT Isolation Power System by Sichuan Yachen Electricity Co., Ltd. is engineered to meet the rigorous safety standards of IEC 60364-7-710 and GB 51348. Unlike standard TN/TT grounding systems, the YCIT system utilizes a high-precision isolation transformer and an advanced 32-bit ARM-based insulation monitor to detect leakage currents as low as 10μA. By ensuring that the power supply remains uninterrupted even during the first insulation fault, this system provides a "safety wall" for life-support equipment, effectively eliminating the risk of micro-shocks to patients while maintaining operational stability for medical teams.

Product Specification: Medical IT Isolation Power System

1. System Overview

In the specialized environment of a hospital, leakage currents pose a potential life-threatening risk to patients. The Medical IT System, also known as the Medical Isolated Power Supply System, is specifically engineered to provide a safe and reliable power source for critical locations. These include operating theaters (OT), intensive care units (ICU), and cardiac surgery rooms.

The primary objective is to ensure that all live conductors within the protected area are isolated from the ground, thereby preventing dangerous micro-shocks caused by insulation failures. The system utilizes an isolation transformer in conjunction with an insulation monitor to continuously track the resistance and current between the secondary side live conductors and the earth

2. Technical Standards & Compliance

Smart Management: RS485 communication allows for central monitoring via PC or building management systems (BMS)

2. Medical IT Isolation Power System

System Overview

In sensitive hospital environments (Operating Theaters, ICU, Cardiac Surgery), leakage currents pose life-threatening risks. The Medical IT System ensures a safe, reliable power supply by isolating all live conductors from the ground, preventing micro-shocks.

Classification of Medical Locations:

Group 0: No medical electrical equipment used on patients (e.g., waiting rooms).
Group 1: Equipment used externally or non-critically (e.g., wards, X-ray rooms).
Group 2: Life-support equipment or intracardiac procedures (e.g., OT, ICU, CCU). IT systems are mandatory here to ensure the leakage current does not exceed 10μA and power is not interrupted during the first insulation fault.

Compliance Standards

GB/T 16895.24 / IEC 60364-7-710: Special installations for medical locations.
GB/T 19214 / IEC 62020: Residual current monitors.
GB 50333: Building technical code for hospital clean operating departments.
GB 51348: Electrical design standards for civil buildings.
