Design-in Guide - Philips Xitanium LED Xtreme SR driver
Adjustable Output Current (AOC)
Flexibility in luminaire design is ensured by the adjustable output
current (AOC). The adjustable output current enables operation of
various LED configurations from different LED manufacturers whilst
also ensuring the solution remains "future proof" for new LED
generations. The output current can configured with the Philips
MultiOne Software and the SimpleSet interface. More information
about AOC and how to set the output current can be found in the
section "Electrical design-in". Information about configuring drivers
with SimpleSet can be found in the section "Configurability".
LED Module Temperature Protection (MTP)
Adjustable limitation of thermal stress on the LED module is
made
possible by the Module Temperature Protection (MTP)
feature combined with an NTC resistor integrated in the
LED
module. More

resistor can be found in the Section "Thermal design-in".
Driver Temperature Limit (DTL)
Adjustable limitation
of thermal stress on the driver is
made possible
by
the
NTC
resistor integrated in the driver. Depending on luminaire
design, DTL can also be used as alternative for MTP. More details
about DTL can be found in the Section "Thermal design-in".
Dimming interfaces
Interfacing with the Xitanium LED Xtreme SR drivers can be done
via the SR interface.
Amplitude Modulation (AM) dimming
Philips Xitanium LED Xtreme SR drivers dim the output to the
LEDs by means of continuous Amplitude Modulation (AM)
dimming of the DC output current. No Pulse Width Modulation
(PWM) is applied across any part of the entire output
current range. AM

components are specified in the driver datasheet.

that power is turned off before doing so.
DC mains operation
Xitanium LED Xtreme SR drivers support operation in a DC power
grid (e.g. central emergency system). The driver behavior once
switched to DC input voltage can be programmed via MultiOne
software. More details about DC input voltage suitability can be
found in the driver datasheet.
