Equipment Description
The CHP Max AC power supply (P/N CHP-PS/AC1) can no longer be purchased; it has been
replaced by the P/N CHP-PS/AC1-Q power supply with identical specification but uses a
dual-speed fan to allow operation at a reduced noise level and P/N CHP-PS/AC1-SW high
wattage power supply. The low noise power supply operates in the low speed mode when
the ambient temperature surrounding the power supply is less than 31°C and operates in
the high speed mode when the ambient temperature is above 31°C. To achieve full noise
reduction, the chassis with eight quieter dual-speed fans (CHP-CHASSIS-19Q) must also be
used. The CHP Max AC power supplies (P/N CHP-PS/AC1-Q and CHP-PS/AC1-SW) are efficient,
switched-mode modules that accepts AC input from 85 to 264V
AC. This hot-swappable
module produces 246 watts (P/N CHP-PS/AC1-Q) or 475 watts (P/N CHP-PS/AC1-SW) to
provide the DC power required to operate one fully-loaded chassis of application modules.
