Diitao 4Pcs Tec1-12703 Semiconductor Refrigeration Tablets Heatsink Thermoelectric Cooler Cooling Plate Cooler Module 12V 6A Pel

Model: Tec1-12703;Voltage: 12V.Umax (V): 15.5V;Max Current (A): 3A.Cooling Power: Qcmax 18Wresistance: 4.0-4.3O?Tmax(Qc=0): Up To 60Coperates Temperature: -55C To 83Cpower Cord: 29Cmrefrigerator Test Method: Hold The Sides Of The Cooling Chip With One Hand, And Press The Wires Of The Cooling Chip Against The Poles Of The Battery With The Other Hand. The Red Wire Is Pressed On The Positive Electrode, And The Black Wire Is Pressed On The Negative Electrode. If One Side Is Slightly Cold And The Other Side Is Slightly Warm, It Means That The Cooling Plate Can Work Normally.Tip: The Working State Is Heating And Cooling. When The Cooling Part Begins To Work, The Hot Surface Must Dissipate Heat Well. The Heat Sink Cannot Be Powered On For More Than 2 Seconds. The Power Supply Of The Hot And Cold Exchange Should Be Carried Out When The Hot And Cold Side Is Restored To Room Temperature, Which Is Generally Greater Than 5 Minutes, Otherwise It Is Easy To Cause Damage To The Refrigeration Chip Circuit And The Ceramic Plate.
