Description

SPDCPOE03 is a power module specifically designed to provide an isolated, low-voltage

power source to a remote powered device (PD) in power over ethernet (PoE) applications.

SPDCPOE03 has full functional compliance with IEEE802.3af. It is designed to extract

power from Ethernet cable when sourced by power sourcing equipment (PSE) also

conforming to IEEE802.3af. SPDCPOE03 is rated 10 W and incorporate PD detection and

PD classification current signatures required for the PSE. The module is compatible with PD

classifications class 0. In addition to a fully integrated DC-DC converter, each SPDCPOE03

power module incorporates internal input diode bridges to support both data line and spare

line pair standard ethernet connections, a transient suppressor for input over-voltage

protection, and an EMI filter to ensure noise compatibility with Ethernet data signals. Other

features include: input under voltage lockout (UVLO), soft-start, over-current and short-

circuit protection.
