Description

The PM100A modules are designed to extract power over Ethernet (PoE+) from a Power Sourcing Equipment (PSE) through a Category 5E Ethernet cable, to provide Power Device (PD) a stable DC voltage in compliant with the IEEE 802.3at PoE+ standard.

The PM100A series have two pairs of power inputs pins: VA1&2 and VB1&2, to accommodate IEEE 802.3at allowing for two power options with Category 5E cables as the following figure. The PM100A modules provides the PoE compatibility detection and power classification required by the Power Sourcing Equipment and up to 25W power to the Powered Device (PD).

With non-isolated regulation, PM100A provides low ripple and low noise output. In addition, PM100A implements protections for output overload, output short-circuit, and thermal shut-down. The modules also provide selections for PoE Class 0 to Class 4 equipments. The high efficiency DC/DC converter operates over a wide input voltage range from 43V to 57V.
