Features: Semiconductor refrigeration is a kind of refrigeration technology which produces negative thermal resistance, which is characterized by non-moving parts and high reliability. Suitable for small space cooling, semiconductor refrigeration learning theory, research solutions developed cooling equipment planing. 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. It is characterized by no moving parts and high reliability. Specifications: Input voltage: 110V - 220V Plug: US plug Working voltage: 12V Working current: 6A Weight: 1190-1197g 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 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、Suitable for small space cooling, semiconductor refrigeration learning theory, research solutions developed cooling equipment planing 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、It is characterized by no moving parts and high reliability
