High Isolation PoE Transformer Security Camera Systems

Product Overview

The EP7 PoE Transformer is a high-performance flyback-type magnetic component exclusively engineered for PoE PD applications, serving as the core device for power conversion and isolation in Ethernet-powered systems. This isolated PoE power transformer specializes in step-down DC voltage conversion and galvanic isolation for DC power transmitted via Ethernet cables, delivering regulated and stable isolated power to meet the strict power supply requirements of various end-user PoE devices. With a wide input voltage range of 36 V to 57 V DC (compatible with the core voltage requirements of IEEE 802.3af/at PoE standards), it supports switching frequencies from 200 kHz to 500 kHz and maintains reliable operation in an extreme temperature range of –40 °C to +125 °C. Boasting a galvanic isolation rating of up to 2400 VAC for 60 seconds, the EP7 flyback PoE transformer provides robust electrical safety protection for PoE systems, making it a staple component for network equipment manufacturers and industrial IoT solution providers.

Core Advantages

Wide Operating Range for PoE Compatibility

The EP7 PoE Transformer features a 33-57V DC wide input voltage range, perfectly matching the voltage drop characteristics of Cat5e/Cat6 Ethernet cables over 100-meter transmission distances, and is fully compatible with IEEE 802.3af/at PoE standards. Its 200-500 kHz switching frequency adaptability supports high-frequency power conversion designs, reducing the size of PoE PD modules and optimizing circuit layout.

High Galvanic Isolation & Industrial-Grade Reliability

With a standard isolation rating of 1500 VAC (up to 2400 VAC for specific models) for 60 seconds, the transformer effectively isolates the power supply side and the load side, preventing electrical interference and surge damage. It operates stably in -40°C to +125°C, adapting to harsh outdoor and industrial environments such as outdoor surveillance and industrial access control systems.

Versatile Output Configurations

Offering multiple inductance values (44μH to 521μH) and output voltage/current combinations (3.3V/0.91A, 5V/2.3A, 12V/0.25A), the EP7 PoE Transformer can be flexibly matched with different low-power and medium-power PoE devices, eliminating the need for custom magnetic component development and shortening product R&D cycles for customers.

Compact Design for High Integration

The transformer’s optimized structural design features a small footprint, suitable for high-density integration in PoE PD modules of IP cameras, wireless LAN access points and other compact devices, meeting the miniaturization trend of modern network equipment.
