Description

The BG CUB1-02 bell transformer provides a reliable low-voltage power supply for compatible wired doorbells, door chimes and signalling equipment. It converts the incoming 230–240V AC mains supply into a choice of 8V, 12V or 24V AC, allowing an electrician to select the correct output for the connected doorbell or chime system.

This makes the CUB1-02 a practical choice for wired doorbells that require a separate transformer rather than an integrated mains supply. Depending on the selected output, it provides up to 1A at 8V, 0.667A at 12V or 0.333A at 24V, with a total rated power output of 8VA.

The transformer has a compact two-module DIN-rail design and can be installed inside a compatible BG consumer unit or electrical enclosure. Locating the transformer inside the consumer unit creates a tidy, protected installation without requiring a separate external transformer enclosure near the doorbell.

Its standard 35mm DIN-rail fitting helps electricians install or replace the transformer quickly. The terminals accept conductors up to 16mm², while the unit is designed for continuous indoor operation and has an operating frequency of 50/60Hz.

FAQ's

What does the BG CUB1-02 do?

It reduces the mains voltage to a safer low-voltage AC output suitable for compatible hard-wired doorbells, chime units and signalling equipment.

What output voltages are available?

The transformer provides selectable outputs of 8V AC, 12V AC and 24V AC.

What is the transformer’s power rating?

The CUB1-02 has an 8VA rated power output.

What current does each output provide?

The official technical data lists:

8V output: 1A
12V output: 0.667A
24V output: 0.333A

The connected doorbell or chime must be compatible with the selected voltage and available current.

Is the CUB1-02 suitable for doorbells?

Yes. BG specifically identifies it for powering compatible wired doorbells and chime units that require a separate low-voltage AC supply.

Does it work with wireless doorbells?

It is intended for compatible hard-wired doorbell and chime systems. Battery-powered or fully wireless doorbells normally do not require a DIN-rail transformer.
