Product Specifications

Technical details and manufacturing context for Emergency Power System

Definition
An emergency power system is a critical component of clean room environment systems that provides uninterrupted electrical power during utility power outages or fluctuations. It ensures continuous operation of essential equipment such as HVAC systems, air filtration, pressure controls, monitoring systems, and safety devices, preventing contamination risks and maintaining controlled environmental conditions. This system is designed for integration into clean room facilities where power continuity is paramount. It monitors the main power supply and, upon detecting a failure, voltage drop, or frequency deviation, automatically switches to backup power sources, typically generators or UPS systems, within milliseconds. The system is available in output power ratings from 10 to 100 kVA, with transfer times of 10 milliseconds or less, ensuring seamless transition. Output voltage is three-phase at 220/380 V AC, with voltage regulation of ±1% and frequency regulation of ±0.5%, meeting the stringent requirements of sensitive equipment. Battery backup time ranges from 15 to 120 minutes at full load, depending on configuration. The system operates in temperatures from 0 to 40°C, with derating above 40°C, and relative humidity from 20% to 90% non-condensing. Ingress protection ratings range from IP20 to IP54, suitable for clean room environments. Noise level is 65 dB(A) or less at 1 meter. Typical dimensions for a 10 kVA unit are 600×800×1200 mm (W×D×H), and weight ranges from 150 to 300 kg depending on battery capacity. Materials include copper wiring, steel enclosures, electronic components, and battery cells. The system complies with relevant standards such as IEC 62040 for uninterruptible power systems, IEC 60038 for voltage, and ISO 3744 for noise measurement. It is essential to verify model-specific values and standards with the legal manufacturer or supplier before procurement.
Working Principle
The system continuously monitors the main power supply. When a power failure, voltage drop, or frequency deviation is detected, it automatically switches to backup power sources (typically generators or UPS systems) within milliseconds to maintain power continuity to critical clean room loads. This ensures that essential equipment such as HVAC, filtration, and monitoring systems continue to operate without interruption, preventing contamination and maintaining controlled environmental conditions.

Risk, maintenance & compliance

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Battery Sulfation
Cause: Prolonged undercharging or inactivity leading to lead sulfate crystal formation on battery plates, reducing capacity and increasing internal resistance.
Fuel System Contamination
Cause: Water ingress, microbial growth, or particulate accumulation in diesel fuel tanks and lines, causing injector clogging, corrosion, and combustion issues.
Maintenance Indicators
  • Extended cranking time or failure to start during weekly/monthly testing
  • Unusual exhaust smoke (white/blue/black) or abnormal engine noise during operation
Engineering Tips
  • Implement automated battery monitoring with temperature-compensated charging and regular load testing to prevent sulfation
  • Establish fuel polishing procedures with scheduled tank inspections, biocide treatments, and water separation to maintain fuel integrity
