Solution Overview
Medical power security directly determines patient life safety and the accuracy of clinical diagnosis. Operating rooms, ICUs, radiology equipment, hospital HIS/PACS servers and laboratory instruments cannot tolerate grid surges, voltage fluctuations or power outages. Any power abnormality may trigger suspended surgery, distorted CT/MRI images, lost patient medical data, and even fatal risks for critically ill patients.
Consnant CNG310 (3Ph Input / 1Ph Output) & CNG330 (3Ph Input / 3Ph Output) Low Frequency Online UPS series delivers a full-spectrum medical-grade power protection solution, covering 10–800KVA power tiers as specified in the official product brochure. Adopting online double-conversion (VFI) topology with built-in output isolation transformer, IGBT power devices and full DSP microprocessor control, the series is certified by ISO, IEC and CE, fully complying with global medical electrical safety standards. It is widely deployed in community clinics, general hospitals and tertiary medical complexes to build an all-round stable power barrier for electro-medical equipment.
1. Core Power Challenges Faced by Medical Institutions
- Zero-switch power backup for life-support equipmentVentilators, anesthesia machines, extracorporeal circulation devices and multi-parameter monitors require 0ms transfer time. Even millisecond power interruption will cut off real-time vital sign monitoring. Ordinary UPS with transfer delay cannot meet ICU and operating room standards.
- Anti-inrush & anti-interference protection for high-precision imaging equipmentCT, MRI, DR and linear accelerators generate massive instantaneous inrush current during startup, while grid harmonics and leakage current cause image artifacts. Built-in isolation transformer of low-frequency UPS suppresses common-mode noise and withstands 300% instantaneous overload, avoiding equipment shutdown and blurred scanning images.
- Leakage current isolation for patient contact zonesIEC medical electrical codes mandate galvanic isolation for wards where patients directly touch medical equipment. Transformerless high-frequency UPS cannot eliminate residual leakage current, bringing hidden electric shock risks.
- Complex unstable grid environment in medical buildingsHospital grids mix air conditioners, elevators, medical devices and industrial loads, resulting in ±20% wide voltage swing and high harmonic distortion. The CNG series features ±20% ultra-wide input voltage range and built-in EMI filters to adapt to aging hospital power distribution systems.
