DC Power Supply

Each DC power supply weighs approximately 3.8 lb (1.7 kg) and consists of one DC
input (–48 VDC and return), one 40 A (–48 VDC) circuit breaker, a fan, and LEDs to
monitor the status of the power supply. Figure 19 on page 30 shows the power
supply. Each DC power supply has a single DC input (–48 VDC and return) that
requires a dedicated facility circuit breaker.
