Why Choose the ABB TS88SW Bell Transformer?
The ABB TS88SW, type TS 8/8SW, is a compact 8 VA bell transformer designed to provide safety extra-low voltage (SELV) power for doorbells, chimes and other loads requiring a discontinuous supply. Part of the ABB System pro M compact TS series, it converts a 230 V AC primary supply to an 8 V AC secondary output.
The TS 8/8SW provides electrical isolation and separation between its primary and secondary circuits and incorporates a thermal protection device in the secondary. This makes it a non-inherently short-circuit-proof transformer designed to withstand short-circuit currents while providing a safe isolated low-voltage supply.
With a rated secondary current of 1 A, an integrated 0-1 switch for controlling the connected secondary load and a compact two-module DIN-rail format, the TS 8/8SW is well suited to residential, commercial and building-control distribution boards where a dependable 8 V AC supply is required.

Reliable SELV Power for Bell and Signalling Circuits
Bell transformers reduce mains voltage to a safety extra-low voltage suitable for compatible signalling equipment. The ABB TS 8/8SW converts a 230 V AC supply to 8 V AC, providing an isolated secondary circuit for doorbells, chimes and other intermittently operated low-voltage loads.
The TS series incorporates thermal protection in the secondary circuit to provide resistance to short-circuit currents. On the TS 8/8SW, ABB also provides an integrated 0-1 switch for convenient control of equipment connected to the secondary, while the modular DIN-rail construction enables straightforward integration alongside other electrical protection and control devices.
Typical Applications
- Doorbell and door-chime circuits.
- Low-voltage acoustic signalling equipment.
- Building entrance and notification systems.
- Residential and commercial distribution boards.
- SELV circuits requiring an 8 V AC discontinuous supply.
- Building control and signalling installations.
- DIN-rail-mounted low-voltage power supplies.
