KEMO M 175 - High-performance ultrasonic animal repeller

"This ultrasonic generator generates very loud siren-like pulsating, aggressive ultrasonic sounds that are perceived by many animals as extremely unpleasant, and therefore are largely avoided (very frequently, not always the case though!). The generator should be used to keep rodents, insects, crawling parasites, game and birds away. If larger areas are to be covered, up to 2 additional loudspeakers No. L020 can be connected (not included). The tone frequency is adjustable between ultrasound (not audible for the human ear) and loud and high tones that can be heard by the human ear. Technical data Operating voltage 12 - 14 V/DC via stabilized power supply or 12 V battery > 12 Ah (not supplied) Power consumption max. 150 mA Adjustable frequency range approx. 7 kHz - 38 kHz. Siren-like pulsing LED displays one LED for ""Power On"" and ""acoustic"" each Connections for up to 2 additional loudspeakers L020 (not included) Acoustic range 100 m, can be extended with additional L020 speakers Sound pressure up to 135 dB (±30 %) (ultrasonic devices should have sound pressure level of over 100 dB(C), in order to prevent habituation (result: ADAC test).
