Velleman SV1 Summer with Continuous and Pulsed Operation, 12V

Velleman SV1 Summer – 105V Sounder with Continuous and Pulsed Operation

The Velleman SV1 Summer is a compact 1V sounder designed for electronic circuits and DIY projects. It delivers a loud 1 dB output at 12 mA draw, making it suitable for alarms, notification systems, and prototype builds.

• 105 dB sound output at 12V ensures high audibility in noisy environments
• Continuous and pulsed operation modes provide flexible alert signalling
• Compact design with wire connectors for straightforward PCB mounting
• Low current draw of 30 mA keeps power consumption minimal in battery-powered circuits

What sets the SV1 Summer apart

The dual-mode operation (continuous and pulsed) distinguishes this sounder from single-mode alternatives. The integrated wire connectors eliminate the need for soldering, enabling quick prototyping and easy replacement in existing designs.

Ideal for...

Electronics hobbyists, makers, and students working on alarm circuits, timer projects, or any application requiring an audible signal. The 12V operating voltage makes it a natural fit for Arduino, Raspberry Pi, and other common development platforms.

Application of Velleman SV1 Summer

Connect the sounder to a 12V DC supply and a control signal line. Use the continuous mode for sustained alerts and the pulsed mode for intermittent warning signals. Mount on a breadboard or PCB using the integrated wire connectors.
