AC input power connection
The Multioutput Asterion DC Series power source is designed to operate from 1-phase
or 3-phase input power, having 2 wire/3-wire plus ground, with nominal AC input
voltage (Refer Table 2-3), and 50/60 Hz input frequency. The AC input voltage range
is automatically selected by the unit at power-up; no user setup is required. Power
factor correction (PFC) provides high power factor, minimizing the required input
apparent power and current harmonic distortion. Refer to the specifications of Section
1.2 for AC input current requirements, and derating of output power as a function of
AC input voltage.
2.8.1
AC input overcurrent protection
The Asterion DC Multioutput Series power source has fuses at the AC input for fault
protection. These fuses are internal to the chassis and are not user accessible. They
provide fault isolation in case a failure occurs of internal components or wiring. A
suitable overcurrent protection device must be provided externally, within the system
installation, to protect the external wiring and interconnects.
