KAOYI KTB-300A Electronic Transformer 50-300W 11.4V LV Halogen Transformer round 230-240V Replacement Transformer

KAOYI KTB-300A Halogen Transformer 50–300 W at a Glance

The KAOYI KTB-300A electronic transformer is designed for high-performance 12V low-voltage halogen lighting. It converts an input voltage of 220–240 V AC to 11.4 V AC and is particularly suitable for larger ceiling lights, multiple spot systems, and lighting tracks with a correspondingly high total halogen wattage.

With a power range of 50 to 300 W, a soft-start function, and integrated overload and short-circuit protection, this round halogen transformer offers a reliable solution for repairing and replacing compatible low-voltage lighting systems.

50–300 W for high-performance halogen systems

The 12V halogen transformer with 300 W is intended for lighting systems with a total power output between 50 and 300 W. This makes it particularly suitable for larger multi-light fixtures and spot systems with several low-voltage halogen lamps.

11.4 V AC output voltage

On the output side, the KTB-300A provides a voltage of 11.4 V AC. The transformer is therefore designed for suitable 12V low-voltage halogen lamps and corresponding halogen lighting systems.

Soft-start and integrated protective functions

The integrated soft-start function reduces the load on the connected halogen lamps when they are switched on. In addition, the transformer features SELV safety extra-low voltage as well as overload and short-circuit protection.

Round design for installation and ceiling mounting

With a diameter of 118 mm and a height of 38 mm, the transformer features a compact, round design. This makes it particularly suitable for installation in compatible ceiling lights and lighting systems with a corresponding housing.
