Description
The ABB TM4012 modular safety transformer (TM40/12 series) is designed to power SELV safety-low voltage devices, such as doorbells, buzzers, or acoustic signals. The primary is 230 V~ while the secondary supplies 4 V, 8 V, or 12 V AC, managing up to 40 VA.
Suitable for installation on a 3-module DIN rail, it guarantees double insulation between the primary and secondary windings, compliance with IEC/EN 61558-2-8 standards and IMQ certification.
Ideal for residential and commercial environments where intermittent power supply is required in complete safety.
