The FNP1500/1800 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
2
LEDs, logic signals, and via an I C management
2
interface. In addition, the I C 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
RoHS compliant for all six substances standards and display the CE-Mark for the
European Low Voltage Directive (LVD).
