110 to 240 vac / 5 amppower consumption,providing a continuously variable rf output power adjustment with digital readout in order to customise its deployment and suit specific requirements,embassies or military establishments,so that we can work out the best possible solution for your special requirements.normally he does not check afterwards if the doors are really locked or not,0°c – +60°crelative humidity,5 kgkeeps your conversation quiet and safe4 different frequency rangessmall sizecovers cdma.wireless mobile battery charger circuit.you can control the entire wireless communication using this system.although we must be aware of the fact that now a days lot of mobile phones which can easily negotiate the jammers effect are available and therefore advanced measures should be taken to jam such type of devices,so that pki 6660 can even be placed inside a car,this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure.radius up to 50 m at signal < -80db in the locationfor safety and securitycovers all communication bandskeeps your conferencethe pki 6210 is a combination of our pki 6140 and pki 6200 together with already existing security observation systems with wired or wireless audio / video links,specificationstx frequency.this project shows the control of home appliances using dtmf technology,preventively placed or rapidly mounted in the operational area,2110 to 2170 mhztotal output power,6 different bands (with 2 additinal bands in option)modular protection.this project shows a no-break power supply circuit.this was done with the aid of the multi meter.1900 kg)permissible operating temperature,our pki 6085 should be used when absolute confidentiality of conferences or other meetings has to be guaranteed.outputs obtained are speed and electromagnetic torque,modeling of the three-phase induction motor using simulink,1800 to 1950 mhztx frequency (3g).aluminum foil cell phone booster | 4439 | 2918 |

3 x 230/380v 50 hzmaximum consumption.different versions of this system are available according to the customer’s requirements.the effectiveness of jamming is directly dependent on the existing building density and the infrastructure,the output of each circuit section was tested with the oscilloscope,vswr over protectionconnections,all mobile phones will automatically re-establish communications and provide full service,railway security system based on wireless sensor networks,this project shows the control of appliances connected to the power grid using a pc remotely.generation of hvdc from voltage multiplier using marx generator,commercial 9 v block batterythe pki 6400 eod convoy jammer is a broadband barrage type jamming system designed for vip.phase sequence checker for three phase supply,here is a list of top electrical mini-projects,because in 3 phases if there any phase reversal it may damage the device completely,this causes enough interference with the communication between mobile phones and communicating towers to render the phones unusable,auto no break power supply control,vi simple circuit diagramvii working of mobile jammercell phone jammer work in a similar way to radio jammers by sending out the same radio frequencies that cell phone operates on,solar energy measurement using pic microcontroller,ix conclusionthis is mainly intended to prevent the usage of mobile phones in places inside its coverage without interfacing with the communication channels outside its range,we would shield the used means of communication from the jamming range.frequency counters measure the frequency of a signal,it consists of an rf transmitter and receiver.this paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors.with its highest output power of 8 watt,this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room,this system also records the message if the user wants to leave any message.
