General description Get ice cold in minutes or heat to boiling by simply reversing the polarity. This thermoelectric heatsink cooling plate is ideal for various CPU cooler applications and can be used for custom car heating or cooling systems. Technical specifications Model: TEC1-12706 Size: 40mm x 40mm x 3.8mm Voltage: 12V Maximum Voltage (Umax): 15V Current (A): 5.8A Maximum Power (QMax): 65W Power cord length: 300mm Net weight: 22g Color: White Material: Ceramic Installation Installation is straightforward: find a battery and connect it to the two wires of the cooler. You will notice that one end becomes cold while the other becomes hot, depending on the polarity. Note that the hot side requires a heatsink at all times. Usage Experiments show that using two refrigeration units is significantly more effective than a single unit. You can choose from three different conditions, provided you have adequate power supply support. Other information Package includes: 4 x TEC1-12706
