Module DC-DC 1-OUT 12V 0.85A 10W 13-Pin DIP Module

The PTB48540 series of power modules is specifically designed to provide an isolated, low-voltage power source to a remote Powered Device (PD) in PowerOver-Ethernet (PoE) applications. These modules are rated 10 W and incorporate all the necessary interface requirements to comply with IEEE Std. 802.3af, for managing the input power to the PD from the PoE Power Sourcing Equipment (PSE). This includes PD detection and PD classification current signatures required for the PSE. The modules are compatible with PD classifications, class 0 through class 3.In addition to a fully integrated DC/DC converter, each PTB48540 power module incorporates internal input diode bridges to support both Data Line and Spare Line pair standard Ethernet power connections, an integral transient suppressor for input over-voltage protection, and an EMI filter to ensure noise compatibility with Ethernet data signals.
