The PSR250-12A and PSR250-12A1 power modules support AC and high-voltage DC inputs. They can provide a
maximum output of 250 W. The PSR250-12A provides power module-side intake and port-side exhaust
airflows, and the PSR250-12A1 provides port-side intake and power module-side exhaust airflows.

The PSR250-12A and PSR250-12A1 power modules support AC and high-voltage DC inputs. They can provide a
maximum output of 250 W. The PSR250-12A provides power module-side intake and port-side exhaust
airflows, and the PSR250-12A1 provides port-side intake and power module-side exhaust airflows.

Protection against over-current input, under-voltage input, over-voltage output,
output current limiting, output short circuit, and over-temperature.

When you install two power modules on a device, the two power modules
support 1+1 redundancy and load sharing.
You can install or remove a power module when the switch is operating properly.

Provide output overvoltage, short-circuit, overcurrent, and overtemperature protections.
Two power modules can be connected in parallel to achieve 1+1 redundancy and load sharing.
Hot swappable. When you hot swap a power module, make sure
the device can operate correctly with the remaining power modules.

The PSR150-A1 is an AC-input and DC-output power module. The PSR150-D1
is a DC-input and DC-output power module. Both power modules provide
an output voltage of 12 V and a maximum output of 150 W.

PSR75-12A is a DC-output power module that supports both AC and DC input.
It provides a maximum output of 75 W.

The power module supports 1+1 redundancy and load sharing and is removable.
It also provides overcurrent, undervoltage, overvoltage, short circuit, overtemperature,
and output current limiting protections.
