The specifications state that PoE supports 30 W and each channel can withstand 720 mA DC balance current. 30 W corresponds to IEEE 802.3at, also known as PoE+. The original text is given by channel. When making a port power supply budget, please understand it according to the original text. Do not multiply the number of channels to convert to the total port current. This paragraph does not apply when the port is to be powered according to 802.3bt Type 3/Type 4. Tell us the target current per port, and VOOHU will confirm the applicable scope based on current controlled data.
Two. There are 8 `1CT:1CT` inside, forming 8 channels and 4 pairsets - each Gigabit port occupies 2 pairsets, so it is a dual Gigabit port. The Chip Side (1–24 pins) and Cable Side (25–48 pins) are clearly marked on the schematic diagram. The same 48-pin 100Mbps device will have four ports, because each 100Mbps port only needs 2 channels; when inferring the number of ports based on the number of pins, you must first determine the speed range, otherwise the difference will be doubled.
Operating temperature -40 °C to +85 °C, covering common temperature ranges in outdoor and industrial sites. The WHDG48209PG has 40 °C more cold end than most 0 °C to +70 °C plug-in Gigabit parts in this catalog. It should be noted that this is the operating temperature range of the device itself. The actual temperature inside the chassis plus the self-heating of the device must fall within this range. Therefore, the device temperature point should still be measured at the highest planned internal temperature of the whole machine and the most unfavorable air duct. The isolation withstand voltage is 1500 VAC/1 mA/60 seconds. The package is plug-in type and is wave soldered.
