Obsolete Product(s) - Obsolete Product(s)Description SPDCPOE05 1 Description SPDCPOE05 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. SPDCPOE05 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. SPDCPOE05 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 SPDCPOE05 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. Table 2.
