Powerful Transformers for PoE++

EPCOS transformers for PoE++ 60 W series are designed specifically for commercial and general use applications

Image of EPCOS' Powerful Transformers for PoE++EPCOS transformers by TDK Corporation are designed for an output of up to 60 W, which is suitable for PoE++ according to IEEE 802.3bt. These devices comprise four types with different turns ratios for output voltages of 3.3 V, 5 V, 12 V, and 24 V. The SMD components have dimensions of 30 mm x 22 mm x 11.4 mm. The electrical insulation of these transformers complies with UL 1446 class 130 (B) and can withstand a high-voltage test between the primary and secondary sides at 1500 VAC, 50 Hz for one second.

An increasing number of devices offer LAN connectivity for communication purposes. The obvious solution, therefore, is to power them via the LAN cable as well (Power over Ethernet), so that no separate power supplies are necessary. Existing systems with two pairs of cables compliant with IEEE 802.3af (PoE) and IEEE 802.3at (PoE+) are designed for outputs of 15 W and 30 W, respectively. The IEEE 802.3bt (PoE++) standard, which is designed for four pairs of cables, has been developed in order to supply devices with a higher power demand. The EPCOS transformers are designed specifically for this application segment.
