Siemens Transformer with buzzer 230/12V AC 4VA DIN 4AC00412R

Compact and efficient Siemens transformer for the Electrical Panelboard

The Siemens transformer with built-in buzzer is the ideal solution for residential and tertiary applications where it is necessary to safely, quietly and efficiently reduce voltage from 230V to 12V. With a power rating of 4VA, it is perfectly suited for small loads such as doorbells, buzzers or low-voltage devices.

230/12V AC Voltage and Integrated Buzzer

Designed to work with alternating current, this transformer accepts a standard 230V AC (50Hz) input voltage and provides a stable 12V AC output, perfect for low-voltage systems. The presence of the built-in buzzer also allows its use as a buzzer in call systems or condominium entrances.

Easy DIN-Rail Installation

The compact 2-DIN-module body allows for quick and neat installation inside electrical panels. Standard DIN rail mounting makes it compatible with most civil and industrial distribution boxes. In addition, connection is quick and easy, with robust and secure terminals.

Typical Applications

This Siemens transformer is perfect for:

• 12V intercom and doorbell systems

• Horns for condominium entrances

• Small low-voltage automations

• Installations in modular electrical panels
  
  

High-quality plastic construction ensures insulation, protection and long life, even in heavy-use environments such as entrances and technical rooms.
