Power over Ethernet (PoE) technology continues to play a key role in modern networking equipment by delivering both power and data through a single Ethernet cable. To meet the increasing demand for compact, efficient, and thermally robust power solutions, SHINHOM offers a range of PoE flat transformers designed for high-performance isolated power conversion in networking and IoT applications.
Optimized for High Power Density
SHINHOM PoE flat transformers support power levels of up to 150W with a wide input voltage range of 36V to 57V, making them well suited for IEEE-compliant PoE and PoE+ systems. The low-profile mechanical design, with a height as low as 10.5 mm, allows easy integration into slim and space-constrained electronic enclosures, such as access points, IP cameras, and communication terminals.
Flexible Topologies and Wide Frequency Support
These transformers are compatible with multiple converter topologies, including forward converters, half-bridge, full-bridge, and active clamp designs. With an optimized switching frequency range from 200 kHz to 700 kHz, they help designers achieve higher efficiency and reduced transformer size while maintaining stable performance across varying load conditions.
Reliable Isolation and Thermal Performance
Electrical isolation is a critical requirement in PoE systems. SHINHOM PoE flat transformers provide an isolation voltage of up to 1500VDC, ensuring safe separation between primary and secondary circuits. Designed for demanding environments, they support an extended operating temperature range from –40°C to +125°C, including self-heating, making them suitable for outdoor and industrial installations.
Low DCR windings and controlled leakage inductance contribute to reduced power loss and improved thermal management. This enables higher efficiency operation and supports long-term reliability even in continuous-duty applications.
Surface-Mount Design and Compliance
Most models feature a surface-mount device (SMD) structure, supporting automated assembly and consistent manufacturing quality. The transformers are lead-free and RoHS compliant, meeting environmental regulations for global markets. Selected models also comply with IEC 60950 safety requirements, further enhancing their suitability for commercial networking equipment.
Versatile Application Coverage
SHINHOM PoE flat transformers are widely used in:
PoE power sourcing and powered devices
IP phones and VoIP terminals
Surveillance cameras and network video systems
Wireless access points and routers
IoT gateways and edge devices
Multiple part numbers with different turns ratios, inductance values, and output configurations allow designers to select the most suitable transformer for specific voltage and current requirements.
Conclusion
With a combination of compact flat design, wide input range, high isolation strength, and flexible topology support, SHINHOM PoE flat transformers provide a reliable foundation for modern PoE power systems. Their thermal robustness, compliance with international standards, and adaptability across networking applications make them an ideal choice for OEMs seeking efficient and space-saving power solutions.
