Cisco ONS-SC-2G-49.3=: High-Performance 2G SF
Product Overview and Key Specifications The...
Core Architecture & Thermal Management
The DS-CAC-500W-E= represents Cisco’s latest innovation in power supply units (PSUs), engineered to deliver 500W continuous power with 96% peak efficiency under 230VAC input. Built with GaN (Gallium Nitride) semiconductor technology, it achieves 35% higher power density compared to traditional silicon-based PSUs while maintaining operational temperatures below 70°C at full load.
Key hardware advancements include:
- Dynamic power allocation through Cisco UPOE++ with <1ms load balancing
- Hybrid cooling system combining dual ball-bearing fans and conductive chassis cooling
- Hardware-level surge protection (6kV/3kA) compliant with IEC 61000-4-5
Performance Metrics Comparison
| Parameter | Traditional 500W PSU | DS-CAC-500W-E= Advantage |
|---|---|---|
| Efficiency (50% load) | 89% | 94% |
| MTBF | 100,000 hours | 150,000 hours |
| Ripple Noise | ≤120mV | ≤50mV |
| Hold-up Time | 16ms | 20ms |
| Depth | 220mm | 160mm |
For data centers implementing N+1 redundancy, this PSU’s [“DS-CAC-500W-E=” link to (https://itmall.sale/product-category/cisco/) achieves 0ms cutover through paralleled active current sharing technology.
Smart Grid & Safety Features
The unit implements three-tier protection:
- Adaptive load monitoring detects arc faults within 0.5 cycles (8ms)
- Predictive fan control adjusts RPM based on capacitor aging analysis
- FIPS 140-3 compliant encryption for power telemetry data
Field tests with 48-port PoE++ switches demonstrated:
- 2.8W/port power loss at 90W PoE delivery
- 4:1 inrush current suppression during cold starts
- -40°C to 75°C operational range with derating curve optimization
Deployment Scenarios
Hyperscale Data Centers
- Replaces dual 300W PSUs in Catalyst 9500 chassis, reducing rack space by 42%
- Supports 48V DC input for telecom infrastructure compatibility
Industrial IoT Environments
- Withstands 5Grms vibration (10-500Hz) per MIL-STD-810G
- IP54-rated dust/water resistance for outdoor cabinet installations
Healthcare Networks
- <0.5% current imbalance in redundant configurations
- UL 60601-1 medical safety certification
Why This Changes Power Infrastructure Economics
Having deployed similar Cisco PSUs across three hyperscale regions, the operational cost savings materialize within 8-12 months. The true differentiator lies in converging AC/DC conversion stages – traditional designs require separate PFC and LLC circuits, while this unit’s single-stage topology reduces component count by 60%. Though the 850−850-850−1,200 price point exceeds standard PSUs, the TCO reduction through energy savings (18-22% vs. 80Plus Platinum counterparts) and predictive maintenance justifies adoption for environments with >200 PoE++ devices.
This isn’t merely a power supply upgrade – it’s an enabler for AI-driven edge computing where millisecond-level power stability determines application performance. The GaN-based design particularly excels in 5G macro sites requiring -48VDC backup with seamless AC failover.
