Negative or Positive ION generator

Mains powered ion generator which may be made into a negative or positive ion generator depending on the orientation of the 30 diodes. A neon light indicates whether the kit is on or off. The kit must be built into a box for routine operation. The use of this circuit will greatly benefit your health and will give you a feeling of comfort. It helps clean the air from dust, pollen, smoke and pollution. The increased concentration of negative ions in the air makes it feel fresher, brings a feeling of well being, helps in reducing stress and effectively reduces the severity of symptoms in some respiratory troubles. PCB size: 108mm x 50mm. (4.25"x1.97")
Supply voltage: 120 VAC (CPS57)

Peltier Effect Module (Out of Stock)

When current passes through two different conductors, heat is produced in one and absorbed in the other. Peltier first described this in 1834. Modern semiconductor materials can make p-n junctions which produce large temperature differences. This 4cm x 4cm x 4mm thick module contains 127 p-n junctions connected electrically in series but thermally in parallel. Maximum temperature difference = 59 deg C at 30 deg C ambient with no heat load. Maximum ratings = 13.5V, 4.4A, 36W.(CPS66)
