NFF Series
®
The World’s First Fanless modular power supply, the CoolX600 NFF Series is the
revolutionary new Convection-Cooled modular power supply from Excelsys. It provides an
incredible 600W in a compact 4.5 x 8.5 x 1U package with no fan.
The silent CoolX600 generates no acoustic noise and off ers system designers best in class
performance in effi ciency (>94%) and unrivalled reliability in addition to the most compre-
hensive feature set and specifi cations.
The series comprises two base models. The CX06S is certifi ed to IEC60950 2nd edition for
industrial applications as well as the upcoming IEC62368-1 standard. The CX06M carries
IEC60601-1 3rd edition & IEC60601-1-2 4th edition (EMC) for medical applications. The
CoolX600 can be populated with up to 4 CoolMods, providing up to 8 isolated DC outputs
ranging from 2.5V to 58.0V. Continuing the Excelsys tradition of fl exibility, the CoolX600
is completely user and fi eld confi gurable. Outputs can be adjusted to the required set
point voltages and can be confi gured in parallel or series for higher current and/or higher
voltages. CoolPacs can be paralleled for higher power and N+1 Redundancy applications.
There are a range of CoolMods available including medium and high power single outputs
and dual modules.
