2.3 EPS30-4815AF External AC Power Supply System
This section describes the EPS30-4815AF external AC power supply system in terms of the
appearance, functions, front panel, and technical specifications.
2.3.1 Structure and Functions
The EPS30-4815AF external power supply system inputs 220 V AC power and converts the
power to -53.5 V DC required by the ATN 950B. When input of the 220 V AC power stops, the
EPS30-4815AF automatically switches to the storage battery, which provides power to the
equipment. This ensures uninterrupted power supply to the equipment. The EPS30-4815AF
consists of the rectifier modules, monitoring module, and AC/DC power distribution frame.
