The Bel Power Solutions FNR-3-48G is a power shelf accessory designed to complement the FNP Series of power supplies. This unit is built for high-density applications, offering a power density range of 15.2 to 18.3 W/in3. It supports a wide input voltage range from 85 to 264 VAC, making it suitable for various global power grids.
The FNR-3-48G provides essential system management and power distribution functions. It features an I2C interface for status monitoring and control, allowing for voltage and current limit settings. Protection features include overtemperature, output overvoltage, and output overcurrent protection to ensure system reliability. The power shelf is designed for hot-swap redundant systems and can be configured with up to three AC-DC front-ends in a 1U rack.
This power shelf is compatible with FNP1500 and FNP1800 series front-ends. It is suitable for applications in telecom, datacom, servers, and distributed power systems. The unit is supplied in bulk packaging.
The input voltage range is 85 to 264 VAC.
It provides a 12 V standby voltage and 1A standby current.
It uses an I2C interface for status and control.
It includes overtemperature, output overvoltage, and output overcurrent protection.
The ORing circuits are for true redundant operation, with Vo1 using ORing FETs and Vo2 using ORing Diodes.
The status LEDs include AC OK, DC OK, and Fan Fail/Overtemperature Fail.
The FNR-3-48G is RoHS compliant.
