6PCS TEC1-12706 Semiconductor Refrigeration Tablets TEC1-12706 12V 6A Heatsink Thermoelectric Cooler Cooling Peltier Plate Module 40x40MM

These Peltier coolers came packaged in a box and then bubble packed. Others I have received had one or more units that were cracked and didn't perform or failed quickly.These units were all pristine. Low power testing showed 1A current at 2 volts. Back EMF reduced current draw as the differential temperature increased. All units were virtually identical, showing good product consistency.Units are moisture sealed with silicone RTV. Seal is very consistent. Although quantitative testing has not been performed, emperical observation has shown fast cooling of the cold side (printed TEC12710 SR).Package includes six units instead of five. Excellent product. Recommended.

Unlike others which are falsely labeled, these are labeled accurately at 15A. Testing shows that they consume at least 160-180 Watts, which is maintained as long as the delta T is kept as close to zero as possible.
