Satisfying the low common-mode noise requirement of the IEEE specification, the Powerstax H201 series has an input voltage range of 35 to 75V and provides a precisely regulated 52.5V output.
The very high efficiency of up to 92.5% at full load minimises power dissipation and helps simplify thermal management.
Operating on a fixed frequency with adjustable output voltage, the open frame module has a comprehensive range of features, including overtemperature protection, input undervoltage lockout and output overcurrent protection.
Other functions incorporate output overvoltage protection and remote sense and remote on/off.
An operating temperature range of -40 to +85C and calculated MTBF of 2Mh (80% of full load, 40C case temperature) means that the Powerstax H201 modules are ideal for a wide variety of power-over-Ethernet applications.
Designed to meet UL60950, EN60950 and CE mark requirements, Advanced Power Conversion reckons the Powerstax H201 represents another leading edge DC/DC convertor developed to meet the emerging power-over-Ethernet market.
