Ag9924 and Ag5324
24V POE with Industrial Temperature

Spotlight Ag9900

Ag9924 and Ag5324 are the cutting edge in industrial temperature POE and ultra-miniaturisation from Silvertel. Ag9900 pushes back the boundaries for POE miniaturisation yet again at just 21.2 x 13.9mm in footprint area, and only 13.3mm high, Ag9900M is truly the smallest POE module in the world. Despite its' tiny footprint, Ag9924MT still packs a maximum 12W at 85°C of output power through improved efficiencies in design. Read more about Ag9924M or Ag9900M here. Meanwhile Ag5324 is a 24V output version of the successful POE+ Ag5300 module, capable of delivering 24W of power at 85°C. Samples are available, contact your local distributor for details. Ag5324, Ag9924M, Ag9912M, Ag9905M and Ag9903M are all released.

Ag9900 webAg9900 Series - Ultra-miniature POE

Ag9900 is now the smallest PoE module in the world, superseding the Ag9800. It is designed such that adding just two diode bridges and an electrolytic capacitor to this truly tiny module is enough to enable PoE functionality in a product. Ag9900 is fully compliant to the IEEE 802.3af PoE standard. It provides a POE signature, classification, isolation and DC to DC conversion options for 12V, 5V, 24V or 3.3V, while taking up minimal PCB space. It is ideal for space constrained PoE applications such as IP phones, wall mount appliances, IP cameras, thermostats, smoke detectors and room sensors, and is perfect for a whole range of new IoT and building automation sensors and devices.
