Ag5324 Silvertel

V1.10 March 2021 Datasheet Ag5300 Silvertel Power-over-Ethernet Plus Module Features IEEE802.3at and IEEE802.3af compliant Maximum 30W peak output power* Small Single In-Line (SIL) package size 57.3mm (L) x 14mm (H) Overload, short-circuit and thermal protection Adjustable output voltage Minimal (low cost) external components Low output ripple & noise High efficiency DC/DC converter 1500Vdc isolation (input to output) Silvertel design-in assistance Description The Ag5300** Power-over-Ethernet (PoE+) module is designed to extract power from a conventional twisted pair Category 5 Ethernet cable, conforming to the IEEE 802.3at PoE standard. The Ag5300 has been designed to extract power from Power Sourcing Equipment (PSE) over a conventional twisted pair Category 5 Ethernet cable. The module input conforms to the IEEE803.2at standard for signature recognition and class programming. The high efficiency DC/DC converter operates over a wide input voltage range with a low ripple and low noise output. The DC/DC converter also has built-in output overload, output short-circuit and over-temperature protection and provides a 1500Vdc (input to output) isolation barrier. *For Ag5300 and Ag5324 only. **All references to the Ag5300 also apply to the AG5305 and Ag5324 Silver Telecom 2021 Ag5300 V1.10 March 2021 Power-over-Ethernet Plus Module Datasheet Table of Contents 1 Ag5300 Product Selector
