Description
TM transformers are suitable for use in combination with loads requiring a discontinuous supply at safety extra low voltage (SELV).
The most common application is to provide SELV protection for doorbells and bathroom buzzers in residential environments.
These bell transformers are suitable for loads that require a discontinuous power supply at very low safety voltage and are therefore mainly used in residential settings in combination with ringers and buzzers for the public and in the tertiary acoustic signalling sector.
