DescriptionSPDCPOE122/6 Rev 11 DescriptionSPDCPOE12 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. SPDCPOE12 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. SPDCPOE12 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 SPDCPOE12 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 Features Input voltage range: 38.5 V to 60 V10 W output Based on ST devices integrating standard PoE interface and current mode PVM controllerIEEE 802.3af compliant (PoE standard)Class 0 (zero), 0-12.96 W inputOutput voltage 12 VOutput current 0.8 AOutput voltage 5 %Ripple 1 % rmsTransient response 5 %, load to full load Operating temperature range -40 C to 70 CInput transient suppressorUnder voltage lockoutSoft-startShort circuit protection 1500 VDC input/output insulation Input and ouwithin SELV limitVery compact size, about 86x24.2x17 mm Vertical THT packageRoHS compliantUL 94V-0 flammabilityApplications The target applications are small low power Security system, doors access, cameras, alarms Displays Public address systems Wireless access pointEnvironmental controlTelemetry Remote environmental monitoringTable 1.Device summaryOrder code Nominal input voltageNominal output voltageMax efficiencyNominal power SPDCPOE1248 V12 VTBD %10 Wwww.st.comDescriptionSPDCPOE122/6 Rev 11 Descript specifications, grade definitions and product
