Description

The ST305 is a 16VA bell transformer with 230V AC input and 8V or 12V AC output, providing the highest output of the Hager bell transformer range. It delivers up to 2A at 8V or 1.33A at 12V, suitable for large signalling installations with multiple call points, extended cable runs, or higher-powered chime units.
DIN rail mounted in 3 modules, the ST305 is suitable for commercial installations, larger residential properties, or applications where a single transformer powers multiple doorbell circuits.
Part of Hager’s modular signalling product range, the ST305 complements the ST301 and ST303 for a full range of bell transformer options covering 4VA to 16VA output.
