TEC1-12707 12V 7A Car Refrigerator Semiconductor Refrigeration Plate 1. Chip model: TEC1-12707 SR 2. Temperature difference: 62 degrees Celsius62-63 degrees Celsius65-67 degrees Celsius67-69 degrees Celsius 3. Voltage: 15.8V (MAX) 4. Recommended voltage: 12V 5. Assembly pressure: 85Ncm2 6. Refrigeration capacity: 51W (MAX) 7. Current: 6A (MAX) 8. Working environment: Temperature range -55~83 degrees Celsius (excessive ambient temperature will directly affect the refrigeration efficiency) 9. Packaging process: 704 silicone rubber seal or epoxy resin seal 10. Storage conditions ambient temperature -10~40 degrees Celsius 11. Device characteristics: red line positive electrode, black line negative electrode (literally the refrigeration surface, non-literally the heat dissipation surface) 12. When testing without heat dissipation, there will be a cooling effect. If the power is turned on, the power supply should be unplugged immediately within 1 second, otherwise the refrigeration plate will be easily burned. 13. A radiator or water-cooled heat dissipation device must be installed on the heat dissipation surface, otherwise it will burn. 14. Note: no matter whether it is water-cooled or air-cooled, thermal silicone grease must be applied 15. Single weight: 21g 16. Wire specification: lead length 200-380mm 17. Dimensions: 40x40x3.6mm
