Why Choose the ABB TS401224C Safety Isolating Transformer?
The ABB TS401224C, type designation TS 40/12-24 C, is a compact safety isolating transformer designed to provide reliable extra-low-voltage power for electrical and electronic equipment. As part of ABB's TS-C transformer range, it provides galvanic isolation between the 230 V AC primary supply and its 12–24 V AC secondary circuit.
With a continuous rated power of 40 VA, the TS 40/12-24 C is designed for permanent supply applications including meters, auxiliary electronic equipment and safety extra-low-voltage (SELV) circuits. Its 12 V AC and 24 V AC secondary connections provide flexibility for a wide range of signalling, lighting, building-services and low-voltage auxiliary applications.
The transformer operates from a 230 V AC primary supply at 50/60 Hz and incorporates thermal overload protection that automatically restores operation after the transformer has cooled sufficiently. Its compact four-module DIN-rail construction makes it particularly suitable for installation within modular distribution boards and control enclosures.

Reliable Safety Extra-Low-Voltage Power
Safety isolating transformers provide electrical separation between the primary supply and extra-low-voltage secondary circuits, making them suitable for applications where SELV power is required. The ABB TS 40/12-24 C converts a 230 V AC supply into selectable 12 V AC or 24 V AC outputs while providing 40 VA of continuous rated power.
ABB's TS-C transformers are designed for permanent supply to meters, auxiliary electronic devices and safety extra-low-voltage circuits. Integrated thermal protection limits excessive temperature during overload or short-circuit conditions and automatically restores the supply once the transformer has cooled and the fault condition has been removed.
Typical Applications
- Safety extra-low-voltage (SELV) circuits.
- Meters and auxiliary electronic devices.
- Low-voltage lighting circuits.
- Video-entry and communication equipment.
- Building automation and auxiliary circuits.
- Bathrooms, showers and other applications requiring suitable SELV supplies.
- Fountains and low-voltage outdoor equipment.
- Electro-medical and similar low-voltage applications where the relevant installation requirements are satisfied.
