The GBC 46.0400.25 is a linear stabilized voltage reducer for use in 24 V vehicle electrical systems. It accepts an input voltage of 20 to 30 Vdc and delivers a regulated output of 13.5 ±0.5 Vdc at a maximum continuous load of 10 A, corresponding to 130 W output power.

It is intended for connecting 12 V devices — such as laptops, electric razors, and similar accessories — to the on-board electrical systems of trucks, campers, and boats that operate at 24 V. The metal construction with black finish is suited to the physical demands of vehicle installations.

Key Features

• Input voltage range: 20–30 Vdc
• Stabilized output: 13.5 ±0.5 Vdc
• Maximum load: 10 A
• Output power: 130 W
• Linear regulation technology
• Metal construction, black finish

Product Benefits

• The 20–30 Vdc input range accommodates the voltage variation typical of a 24 V vehicle electrical system under different load and charging conditions
• The stabilized 13.5 V output (rather than a fixed 12 V) matches the correct operating voltage for 12 V devices that expect a charging-level supply
• Linear regulation ensures a clean, ripple-free output appropriate for sensitive electronics such as laptop power supplies
• The 130 W power capacity covers laptop adapters and other high-draw accessories commonly used in professional vehicle cabins
