Infomart PEM9300BT Series Power over Ethernet (PoE) IEEE802.3bt 85W PD Module

PEM9300 Series IEEE802.3bt 85W PD Module

The PEM9300BT is the world’s smallest 85-watt IEEE802.3bt PoE Powered Device (PD) module solution in its class. It is a low-cost solution compliant with the IEEE802.3bt Power over Ethernet (PoE) standard, which includes backward compliance with IEEE802.3at and IEEE802.3af standards. It presents a Type 4, Class 8 signature and supports output power up to 85 watts when sourced from an IEEE802.3bt compliant Power Sourcing Equipment (PSE) capable of providing the required power.
The PEM9300BT provides advanced features not found on most PoE PD modules. These include Maintain Power Signature (MPS) to maintain connection to the compliant PSE under low-power conditions, Auto Class to enable automatic power budgeting, and in-built support for automatic switchover to an external DC power source, such as a wall adapter. The PEM9300BT provides indications for the power class on which the module is functioning, and the type of PSE connected. It has a well-regulated, low-noise, and low-ripple output, with overload, output short-circuit, and in-rush current protections.
The PEM9300BT is available in output voltage variants of 12V, 20V, and 24V. The module features a low-EMI, highly efficient DC-DC converter, which achieves up to 93% efficiency and maintains 1500V isolation between input and output.
