Product Review

This ultrasonic generator produces pulsating and aggressive ultrasonic sounds like a siren which many animals perceive as extremely unpleasant and, therefore, try to avoid as far as possible. The generator should be used to keep away rodents, insects, crawling parasites, game and birds, etc. The frequency of the generator is adjustable between approx. 8 - 40 KHz. A special loudspeaker with vaulted aluminium dome membrane has been built in to achieve a better sound distribution. A stabilised power supply 12 V/DC (< 60 mA) is necessary for setting into operation. Operating voltage12 V/DC (10-13.8 V/DC) Current consumptionca. < 60 mA Adjustable frequencyca. 8 - 40 KHz (± 15%) Frequency deviation, ca. 2 x per secondapp. 2-3 KHz (automatic change of frequency, siren-like) Sound pressuremax. 100 dB (± 15%) (Ultrasonic devices should have a sound pressure level exceeding 100 dB (C) to avoid habituation (ADAC test results).
