The EPS30-4815AF is configured with one or two rectifier modules. When one rectifier
module is configured, the maximum output current is 15 A; when two rectifier modules
are configured, the maximum output current is 30 A.
NOTE
A filler panel must be inserted into an empty slot intended for a rectifier module.
Reserves an active and a standby RS232/RS485 communication interfaces for extended
real-time communication with the equipment in future, and a DB50 interface for
implementing the extended monitoring function in future.
Provides two load interfaces for outputting -53.5 V DC power to two PIUs, which provide
power to the ATN 950B.
Provides two load control fuses, that is, FU-1 with a fuse capacity of 10 A and FU-2 with
a fuse capacity of 20 A. These fuses enable/disable output of the load and provide overload
and short-circuit protection for the load.
Provides one interface for connecting to a group of storage batteries. When working
normally, the EPS30-4815AF is charging the storage batteries. When input of the 220 V
AC power stops, the storage batteries provide power to the ATN 950B. This ensures
uninterrupted power supply to the ATN 950B.
Figure 2-6 shows the appearance of a storage battery and
battery tray with storage batteries.
Provides a storage battery protection fuse, that is, FU-3 with a fuse capacity of 20 A. This
fuse enables/disables the storage batteries and provides overload and short-circuit
protection for the storage batteries.
