UPS (Uninterruptible Power System) is the cornerstone of ensuring uninterrupted power for critical equipment, leveraging energy storage and conversion circuits to provide seamless backup power during mains anomalies. Leading industrial-grade UPS solutions from HIGHIDEA utilize online double-conversion technology to deliver ultra-reliable power protection for data centers, telecom base stations, and other mission-critical applications.
1. Core Working Principle: Double-Conversion Technology
Online UPS systems achieve zero-transfer-time power continuity through two energy conversion stages:
1.1 Rectification & Charging Phase
The AC mains input (e.g., 220V) is converted to DC by a rectifier, which simultaneously charges the battery bank and supplies stable DC power to the inverter.
- HIGHIDEA D3K Online UPS employs high-frequency PWM rectification, supporting an input voltage range of 170V–285V to accommodate grid fluctuations.
1.2 Inverter Power Supply Phase
The DC power is inverted back into a pure sine wave AC output with voltage regulation accuracy of ±1% and frequency stability of ±0.1Hz.
- HIGHIDEA H1K-110 Rack-Mounted Inverter provides 110V/60Hz output, ideal for marine radar and aviation systems.
1.3 Static Switch Transfer
In case of inverter failure or overload, the static switch automatically transfers the load to bypass mains within 4ms, ensuring uninterrupted operation.
- HIGHIDEA MT1000 Standby UPS offers a cost-effective solution for home PCs with a slightly longer transfer time (8–10ms).
2. Key Technical Modules
Energy Storage Unit: Lithium iron phosphate (LiFePO₄) or lead-acid batteries are commonly used. HIGHIDEA’s external 48V Li-ion battery pack supports over 2 hours of runtime with 2,000+ charge cycles.
Filtering & Voltage Stabilization: EMI filters eliminate surge interference at the input, while LC filtering ensures output harmonic distortion <3%.
Intelligent Monitoring: Remote management via RS485/SNMP protocols is supported. HIGHIDEA Power Monitoring Software provides real-time insights into battery health, load levels, and fault alerts.
