Audiotek AT-PS26 26A 13.8V DC Bench Power Supply

The Audiotek AT-PS26 is a regulated AC-to-DC bench power supply designed to provide 13.8V DC power from an AC wall source. It is intended for operating compatible 12V-class equipment without relying on a vehicle battery. With up to 26A of output current, it provides a dedicated stationary power source for workbenches, hobby setups, and equipment testing.

This supply is suited to users who need to power compatible CB radios, scanners, HAM radio equipment, cellular accessories, and other 12V devices from mains power. Its plug-in operation and switch-activated control simplify everyday setup. The fixed 13.8V DC output supports equipment designed around automotive-style DC power.

Rather than producing audio itself, the AT-PS26 supports audio and communications systems by supplying their required DC operating voltage. Its regulated design is specified to provide a constant DC voltage source. This makes it useful where a stable bench-power connection is preferred over temporary battery power.

The unit uses screw-type output terminals for hardwired positive and negative connections. This connection method supports secure attachment of compatible equipment leads and is practical for testing, servicing, or more permanent tabletop installations. Plug-in operation eliminates the need for an external battery as the power source.

For thermal management, the AT-PS26 includes an air-cooling fan and a heavy-duty heatsink. Electronic overload and short-circuit protection are specified to help protect the power supply and connected equipment during fault conditions. Its compact benchtop format fits well as a support component in a radio, car-audio testing, or electronics work area.

Key Features

• 13.8V DC Output: Provides a fixed DC source for compatible 12V equipment.
• Up To 26A Capacity: Supports equipment with higher current requirements within its rating.
• Regulated Conversion: Converts AC power to a constant DC voltage source.
• Screw-Type Terminals: Allows hardwired positive and negative device connections.
• Cooling Fan: Uses forced-air cooling to help manage operating heat.
• Protection Circuitry: Includes electronic overload and short-circuit protection.

Design & Installation

The AT-PS26 uses a rugged housing, integrated cooling fan, and heavy-duty heatsink for benchtop use. Its connection layout combines plug-in AC operation with screw-type DC output terminals. The compact enclosure measures 7.4 x 10.6 x 4.5 inches and weighs approximately 14.8 pounds.

Place the supply on a stable, dry surface with clear airflow around the fan and ventilation areas. Connect compatible DC equipment to the screw terminals with correct polarity, then connect the unit to a suitable AC source and use the power switch to operate it. Confirm that the connected device's voltage and current requirements are compatible before use.
