Inission Power SFA160 - 160 W AC/DC Power Supply
High-Efficiency Power in an Industry-Standard 2" × 4" × 1" Format
System designers working on industrial computers, networking infrastructure, video and broadcast equipment, and automation systems share a common requirement: a reliable, space-efficient AC/DC power supply that fits within standard form factor constraints without sacrificing efficiency or thermal performance.
The Inission Power SFA160 addresses this directly. Delivering 160 W of regulated DC output within the industry-standard 2" × 4" × 1" (51 × 102 × 27 mm) package, it combines high efficiency with a broad operating range and comprehensive protection features - making it a strong fit for a wide variety of industrial and infrastructure applications.
Designed for Industrial, Networking, and Infrastructure Applications
The SFA160 is suited for use across a range of application areas, including:
- DSL, Wi-Fi, and WiMAX base stations
- Networking and communications infrastructure
- Video and broadcast equipment
- Test and measurement systems
- Industrial computers and embedded platforms
- LED industrial displays and monitors
- Automation, drives, and industrial control systems
Technical Characteristics
The SFA160 is engineered to deliver reliable, efficient performance across demanding operating conditions:
- Industry-standard 2" × 4" × 1" form factor for straightforward integration into existing system designs
- Universal AC input range of 90-264 V AC, covering global grid voltages without input switching
- Output voltages of 12 V, 24 V, or 48 V DC as standard
- 12 V / 0.5 A auxiliary fan output for system cooling control
- Output power of 160 W with forced-air cooling; 100 W with natural convection up to 50 °C ambient
- Efficiency greater than 90%, reducing heat generation and improving long-term reliability
- Active Power Factor Correction (PFC) meeting EN 61000-3-2 harmonic current limits
- Operating temperature range of -20 °C to 70 °C (with derating above 50 °C)
- Altitude operation up to 4,000 m without derating, thanks to PCB creepage and clearance values above 8 mm
- Low earth leakage current
- Protection features: fuses on both AC lines, output overcurrent, output short-circuit, output overvoltage, and overtemperature protection
- EN 55032 Class B EMC compliance for conducted emissions
- IEC/EN 61000-3 harmonic content compliance and EN 55024 EMC immunity
- Safety certified to IEC/EN 60950-1, IEC/EN 62368-1, CAN/CSA 60950-1, and CE marked
Efficiency That Supports Better System Design
At over 90% efficiency, the SFA160 generates significantly less heat than lower-efficiency alternatives at the same power level. This directly improves thermal management within the system enclosure, reduces the load on cooling arrangements, and supports longer component lifetimes. For designers working within tight space budgets, the compact footprint and reduced thermal output allow more functionality to be integrated without increasing system volume.
The ability to deliver 100 W continuously under natural convection - without forced airflow - also provides flexibility for fanless or sealed enclosure designs where acoustic performance or ingress protection is a priority.
