Features: Semiconductor refrigeration is a kind of refrigeration technology which produces negative thermal resistance, which is characterized by non-moving parts and high reliability. It can be used in DIY small refrigerators, pet refrigerators, small air conditioners, semiconductor experiments and so on. The cooling effect depends on the size of the cooling space, ambient temperature, adiabatic, sealing etc. Surface large fins design, and straight tube radiating, quick heat dissipation. Simple operation, strong practicability. Specifications: Input voltage: 110-240V Plug: US plug Refrigerator:12V 72W Power supply driver: 12V 10A Size: 120 x 100 x 195 mm / 4.72 x 3.94 x 7.68in Weight: 1340g Wiring method: V+: All red wire (any V+ is ok) V-: All black wire(any V- is ok) L N: Power cable Package included: 1 x Semiconductor refrigeration 1 x power supply 1 x US plug Note: Please kindly make a note if you need any adapter. 1、Semiconductor refrigeration is a kind of refrigeration technology which produces negative thermal resistance, which is characterized by non-moving parts and high reliability 2、It can be used in DIY small refrigerators, pet refrigerators, small air conditioners, semiconductor experiments and so on 3、The cooling effect depends on the size of the cooling space, ambient temperature, adiabatic, sealing etc 4、Surface large fins design, and straight tube radiating, quick heat dissipation 5、Simple operation, strong practicability
