Low-cost, high output sealed Thermoelectric Peltier element measuring 30mm x 30mm, Peltier elements are thermo-electric heating and cooling devices that feature solid state,reliable temperature control, Popular Uses include cooling elements for mini fridges,dehumidifiers and cooling hot running ICs and Cpus such as those used in Computers,basically when connected to a DC power supply they will pump heat from one side of the element to the other meaning one side will get very hot whilst the other side will get very cold,by adding a heatsink and fan to the hot side (a necessity) to dissipate the heat the cool side will remain very very cold,varying voltages from 5v to 16v can be used,Manufacturers technical specifications are as follows,Max Watts 37,Max Temperature Differential 75 degrees C,Max Amps 3.3,Max Volts 16vdc,Peltier elements can also be used to generate free electricity simply by heating one surface and cooling the other, With a sufficient temperature differential a cell can output up to around 1 Amp at 5V ,more than enough to charge small batteries or drive a small electric motor,these things literally have hundreds of different uses and are great for experimenting with,Please Note,the peltiers on offer are moisture sealed around the edges to prevent any corrosion over time.

Small but powerful 6v to 12v electric fence energiser for powering electric fencing either to keep small animals in or to keep them out, popular uses include protection of chicken runs and bantam enclosures though they are also great for dettering small animals such as cats and dogs from specific areas such as vegetable plots,allotments,garden borders and ponds,when used with a 12v battery these electric fence energisers will produce impulses of approx 1500volts,their current consumption however is incredibly small,typically less than 15 milliamps,with such a low current consumption its possible to run one of these from a small 12v 7ah battery for at least a couple of weeks before it will need recharging,a large car or leisure battery will of course last much much longer,by connecting a small 12v solar panel such as one of the 2watt or 3watt models in our store to the battery its very likely that the battery wont ever need to be recharged by a mains battery charger again,these energisers come complete with fused wiring harness with large battery clips for easy battery connection a mounting clip and full instructions, you just need to add a battery,fence wire,insulators,warning sign and an earth stake,please note these energisers need good insulation so insulators are a necessity,price includes uk vat and delivery
