module-side exhaust airflows.
The PSR250-12A1-D provides the following features:
•
Protection—Provides protection against input overcurrent, output current
limiting, input undervoltage, output overvoltage, output short circuit, and
overtemperature conditions.
•
Redundancy—Two power modules can be connected in parallel to achieve 1+1
redundancy and load sharing.
•
Hot swapping—You can install or remove a power module when the device is
operating correctly.
