28V/5A Desktop USB-C power supply

Ideal Use Cases

The Kramer PS-2805-C is a 140W desktop power supply intended for compatible USB-C devices. Its published output combinations are 5V/3.0A, 9V/3.0A, 15V/3.0A, 20V/5.0A, and 28V/5.0A. This range makes the model suitable for desktop equipment that accepts one of those specific voltage and current combinations through a standard USB Type-C connector.

This power supply is particularly relevant when a device requires more than a basic 5V USB source or calls for one of the higher listed outputs. It can address requirements ranging from 5V at 3.0A through 28V at 5.0A without changing the stated connector type. The connected device must be compatible with the applicable output, so its power requirements should be confirmed before the supply is used.

Why Choose This Model

The primary reason to select the PS-2805-C is its clearly defined set of five output combinations. The lower-voltage options provide 3.0A at 5V, 9V, and 15V. The two higher-voltage options provide 5.0A at 20V and 28V. This published information gives buyers concrete values to compare with the input requirements of their USB-C equipment.

Its 140W designation corresponds to the highest listed output combination of 28V at 5.0A. The standard USB Type-C connector provides a familiar physical interface, while the desktop configuration is suited to installations where the supply can remain near the powered device. No claims are provided for dimensions, weight, efficiency, protective functions, or certifications, so selection should be based on the documented connector and output specifications.

Installation and Integration

Integration begins by confirming two separate points: the device must use a compatible USB-C connection, and its accepted power input must match one of the five listed combinations. A USB-C connector alone does not establish electrical compatibility. Checking the powered device’s input information against the PS-2805-C output list is therefore an important part of product selection and installation.

The product is identified as a desktop power supply, making it appropriate for placement alongside compatible equipment in a desk, workstation, or other fixed setup. The supplied source data does not state the AC input range, cable length, physical dimensions, operating temperature, mounting provisions, or included accessories. Those details should be verified separately when they affect space planning or integration requirements.

Performance Highlights

• 5V output at 3.0A for compatible USB-C devices.
• 9V output at 3.0A for equipment accepting that combination.
• 15V output at 3.0A as an additional intermediate option.
• 20V output at 5.0A for devices requiring the listed higher-current profile.
• 28V output at 5.0A, representing the supply’s stated 140W maximum output.

The output list shows that current capacity rises from 3.0A across the three lower-voltage combinations to 5.0A at both 20V and 28V. These exact figures provide a more useful basis for compatibility checks than the 140W rating alone.

What Makes It Different

The defining feature of the PS-2805-C is the inclusion of a 28V/5.0A output alongside four lower-voltage combinations. It is not described merely as a generic USB-C adapter; the source identifies each available voltage and its associated current. That clarity helps distinguish the model when matching a supply to equipment with a specific USB-C power requirement.

The combination of a desktop format, standard USB Type-C connector, and outputs extending from 5V/3.0A to 28V/5.0A gives the product a focused role. It is designed to provide power to compatible USB-C devices while offering multiple stated electrical combinations within one model.

Final Assessment

The Kramer PS-2805-C is a strong match for buyers who need a 140W desktop USB-C power supply and have verified that their device accepts one of its published outputs. Its principal strengths are the standard USB Type-C connector and the precisely stated 5V, 9V, 15V, 20V, and 28V options. For a confident purchase, confirm the required voltage, current, connector, and any installation details not included in the available source data.
