Description

The KPM5900 is the world’s smallest 85 watts 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, with full backward compatibility to IEEE802.3at and IEEE802.3af standards. The module presents a Type 4,Class 8 PD signature and supports output power of up to 85W when powered by an IEEE802.3bt compliant Power Sourcing Equipment (PSE) capable of delivering the required power.

The KPM5900 is designed with Kinetic’s KTA1142 and provides advanced features typically not available in standard PoE PD modules. These include Maintain Power Signature (MPS) to maintain connection to a compliant PSE during low-power operation, Auto-class for automatic power budgeting, and in-built support for automatic switchover to an external DC power source, such as a wall adapter. The module also provides power class and PSE type indications for system monitoring and control. It delivers a well-regulated, low-noise, and low-ripple output, and includes overload protection, output short-circuit protection, and inrush current protection.

The KPM5900 is available in 12V and 24V output voltage variants. It features a low-EMI, highly efficient isolated DC-DC converter achieving efficiencies of up to 93%, while maintaining 1500V safety isolation between the input and output.
