Overview
This manual describes the PSR300-12A, PSR300-12A1, and
PSR300-12A2 AC-input and DC-output power modules, and the
PSR300-12D1 and PSR300-12D2 DC-input and DC-output power
modules. These power modules provide 12 VDC and a maximum output
of 300 W.
Table 1 Features of the power modules
Feature Description
Protection
Output over-voltage protection, output
short-circuit protection, output current-limiting
protection, and over-temperature protection.
Redundancy
The power modules can be connected in
parallel to implement 1+1 redundant load
sharing.
Hot swapping
When a device is operating, you can switch off
a power module of the 1+1 redundant power
system and remove it from the device.
