Kemo M048N Ultrasonic Generator 8-40 kHz 12 V DC Anti-Marten/Animal Repellent Module

The Kemo M048N is an ultrasonic generator designed to emit high-frequency sounds — normally inaudible to humans — useful for repelling animals, rodents, insects and pests.
The emission frequency is adjustable over a wide range — from approximately 8 kHz up to 40 kHz — allowing the signal to be adapted to the type of animal or pest to be deterred.

It operates on a 12–15 V DC power supply and consumes less than 50 mA, for economical and reliable operation. It can drive up to 5 piezoelectric speakers in parallel (speakers not included), allowing you to fill medium-sized rooms with effective ultrasonic sound.

The compact size makes the module easy to install even in small spaces, such as garages, basements, warehouses, campers, stables, gardens, sheds, or storage areas. Once connected, it offers continuous protection against unwanted animals or rodent and insect infestations, without the use of traps or chemicals.

Depending on the type and sensitivity of the animal, the frequency can be adjusted to maximize the effectiveness of the repellent — making the M048N a flexible and customizable solution for domestic, agricultural and industrial environments.
