The Ag9900 series PD modules pushes the boundaries of POE miniaturisation further than ever before, yet still offers all the features expected from Silvertel’s POE. This is the smallest package size available that is designed to extract power from a Cat5 cable, fully conforming to the 802.3af Power-over-Ethernet (PoE) standard and includes 1.5kV isolation, PoE signature and an integral DC to DC converter. The module provides a Class 0 signature.
Ag9900 offers a simple, ultra-small PoE solution using minimal external low cost components. External bridge rectifiers enable the device to be powered from midor end-span PSE, accepting power from either the spare or data pairs of the cable. An integrated optimised DC/DC converter operates over a wide input voltage range with high efficiency (up to 87%). Built-in protection against overloads and shortcircuits is also provided. The regulated DC output nominal voltage is easily adjusted using a simple pull up/down resistor.
