Why Choose the Lovato CTRS25VA Modular Safety Transformer?
The Lovato CTRS25VA is a compact 25 VA modular safety transformer designed to convert a 230 V AC supply to low-voltage 12 V AC or 24 V AC outputs for electrical control, signalling and auxiliary circuits. As part of the Lovato Electric CTRS series, it provides a practical DIN rail solution for installations requiring a dedicated safety transformer within a distribution or control panel.
With a rated output power of 25 VA, the CTRS25VA provides selectable 12/24 V AC secondary voltages from a 230 V AC primary supply. This makes it suitable for supplying compatible low-voltage bells, signalling devices, control equipment and other auxiliary loads requiring an isolated low-voltage AC source.
The CTRS25VA occupies 3 DIN modules and is designed for straightforward installation on a standard DIN rail. Its robust terminal arrangement accepts conductors from 0.5–10 mm², while compliance with IEC/EN 61558-2-8 provides assurance that the transformer is designed specifically for safety-transformer applications.

Safety transformers such as the Lovato CTRS25VA are used to step down mains voltage to a lower AC voltage for compatible auxiliary equipment. By converting a 230 V AC primary supply to 12 V AC or 24 V AC, the transformer provides a convenient source for low-voltage control, signalling, bell and similar electrical circuits.
The modular CTRS design allows the transformer to be installed alongside other DIN rail equipment within an electrical enclosure. The CTRS25VA combines a 25 VA output rating with a compact three-module footprint, making it particularly useful where both 12 V AC and 24 V AC secondary voltage options are required within a modular installation.
Typical Applications
- Low-voltage bell and chime circuits.
- Electrical signalling and notification systems.
- 12 V AC and 24 V AC auxiliary circuits.
- Residential and commercial distribution boards.
- Industrial control panels.
- Building automation and control systems.
- DIN rail installations requiring a 230 V AC to 12/24 V AC safety transformer.
