Bell transformer, 18VA primary 230-240V AC, 50Hz, secondary 8V, 12V AC with PTC fuse, 2TE++ Bell transformers for controlling bells, gongs, door openers or remote switches. The typical application of these bell transformers is short-term use, as occurs with bells, gongs, door openers or remote switches in residential buildings. The secondary rated voltages range from AC 4 V to 24 V. Siemens bell transformers are protected against short circuits or moderate overloads by a PTC resistor. Whether for infrastructure or industrial requirements, Siemens offers bell transformers for all applications and every area of use. The power supplies from Siemens are characterized above all by: 1. Convenient and simple installation and connection technology. 2. Reliable safety during installation thanks to touch protection as standard. 3. Integrated short circuit and overload protection. 4. Optimum technology for a secure power supply for your safety - only from Siemens. www.siemens.de/lowvoltage. Siemens offers a comprehensive portfolio of protection, switching, measuring and monitoring devices, distribution systems as well as switches and sockets for safe, efficient electrical infrastructure in buildings and industry.
