HUNT ELECTRONIC MOSQUITO QUARTZ 9 230 Volts AC Volts DC
SCHEMA HUNT ELECTRONIC MOSQUITO QUARTZ 230 Volts AC Volts DC 9:
The emit signal by the buzzer BZ is very unpleasant for I'ensemble insects and especially mosquitoes.
Its waveform that many harmonics. and therefore ultrasound SONL generes.La frequency of the signal is at the limits of human hearing threshold, the Q quartz can keep it constant. The system can be powered by AC or 230 volts with a single 9-volt battery. The maximum current consumption is 15 mA. The lighting of the LED ensures perfect functioning of the device. CAUTION! When batlerie is inserted, DO NOT connect the device to the mains voltage. WARNING! When the device is connected to the mains voltage 230 Volt AC, it must be very careful when handling. During assembly of the components, you must be very careful to insert the diodes in the right direction. A reversal in recent irreparably damage the assembly.
Given the signal strength (particularly with a supply of 230 Volts AC), the BZ buzzer can generate noticeable vibrations by a loud and unpleasant hiss. This disadvantage can be eliminated by insurant between the buzzer and the circuit will print a thick cardboard or foam rubber.
