High Voltage PoE Transformers

Eaton Electronics High Voltage PoE Transformers include four kinds of transformers: POEA1FB, POEA2FB, POEB3FB, and POEB4FW. Each of these transformers has 1500V_AC isolation between primary and secondary, low leakage inductance, and ferrite core material. These transformers also have an IEEE 802.3xx and a moisture sensitivity level (MSL): 1. Eaton Electronics High Voltage PoE Transformers applications include lighting, industrial automation, security systems, VoIP phone systems, network and BLUETOOTH® access points, network routers, repeaters, uninterruptible power supplies (UPS), retail point-of-information (POI) systems, vending and gaming machines, and remote cameras.
