CTRB15VA Lovato BELL/BUZZER TRANSF 15VA (230VAC/12VAC)

Why Choose the Lovato CTRB15VA Bell Transformer?

The Lovato CTRB15VA is a compact bell and buzzer transformer designed to provide a safe low-voltage AC supply for signalling and control applications. Part of the Lovato modular equipment range, it converts a 230 V AC primary supply to 12 V AC and provides a rated apparent power of 15 VA.

Designed for installation in electrical distribution boards and control panels, the CTRB15VA provides galvanic separation between the mains input and low-voltage output. Its modular DIN rail format allows straightforward integration alongside other modular protection, control and signalling devices.

With its 230 V AC input, 12 V AC output and 15 VA rating, the CTRB15VA is suitable for supplying bells, buzzers and similar low-voltage signalling circuits where a dedicated step-down transformer is required.

Reliable Low-Voltage Supply for Signalling Circuits

Bell transformers reduce mains voltage to a safer low AC voltage suitable for signalling equipment such as bells and buzzers. The Lovato CTRB15VA provides a dedicated 12 V AC secondary supply while electrically separating the low-voltage circuit from the 230 V AC mains input.

Its modular construction makes the transformer easy to incorporate into modern electrical distribution equipment. The 15 VA output capacity provides a practical power source for compatible low-voltage signalling and auxiliary circuits in building and industrial installations.

Typical Applications

• Electric bells and doorbell circuits.
• Low-voltage buzzers and audible signalling devices.
• Building signalling and notification circuits.
• Commercial electrical distribution boards.
• Industrial control and signalling panels.
• Low-voltage auxiliary AC circuits requiring a 12 V AC supply.
