The FNP1800 front-ends are power-factor corrected (PFC) which (depending on model type) provide a 12 VDC or 48 VDC (1500 or 1800 watt)output and can be used in hot-swap redundant systems. Their very small dimensions allow configuration of up to three units in a 1U rack. The FNP front-ends have a front-mounted AC receptacle. The highly efficient thermal design with internal-fan cooling permits their use over wide temperature ranges and provides very high reliability. Status information is provided with front panel LEDs, logic signals and via an I2C management interface. In addition, the I2C bus can enable the power supply, set high fan speed, adjust the output voltage and set the output current limit. The FNP1500/1800's meet international safety standards and display the CE-Mark for the European Low Voltage Directive (LVD).
