1800W 40A1. Using high-quality materials, the quality is guaranteed2. Fan blade heat dissipation is adopted, the heat dissipation effect is very good, and the output power is higher3. The temperature-controlled fan adopts hydraulic bearing fan, which has achieved a good balance in noise and heat dissipation. When the load is light, the fan does not turn. When the load temperature reaches about 60 degrees, the fan automatically rotates. Can effectively reduce noise and prolong service life4. The main power tube insulation board is made of high-quality alumina, and the thermal conductivity is 10 times that of ordinary insulation pads5. Oversized ferrosilicon aluminum magnetic ring, using four 1.2 pure copper enameled wires, low calorific value and high efficiency6. With constant current function, it can be used for car battery boost, battery charging, etc. parameter:Working characteristics:Output power: 1800WInput voltage range: 10V-60VOutput voltage range: 12V-90VInput current: 40AOutput current: 22AConversion efficiency: 48V to 60V 8A (98.1 %)48V to 72V 8A (98.1%)48V 84V 8A (97.6%)Charge Regulation: 10% to 50% charge (72V output)Temperature coefficient: 50% loadRipple and Noise: 20MHz bandwidth (48V-72V 4A) 100mVp-pSwitching frequency: VIN = 48V VO = 72V 4A (110khz)No-load current: VIN = 48V VO = 72V (18mA)Input reverse protection: yesStorage humidity: 95%Operating temperature: -20 65 CStorage temperature: -40 125 COperating Temperature Rise: 48V to 60V 5A (45 C)Overheating Protection: 60CWiring method: input, output (solderless, terminal block).Cooling method: strong air cooling Package list:Boost Converter*1/5/10 1200W 20ADescription:Input voltage: 8-60VInput Current: 20AQuiescent current: 15mA (12V liter 20V, the output voltage, the higher the current will increase too quiet)Output voltage: 12-80V continuously adjustableOutput Current: 20A MAX Over 15A, please enhance heat dissipation (input, output pressure related, the greater the pressure the smaller the output current)Constant Range: 0.5-20AOutput Power:Input voltage * 20A, such as: input 12V * 20A = 240W, input 24V * 20A = 480W,Enter 36V * 20A = 720W, input 48V * 20A = 960W, input 60V * 20A = 1200WIf you need more power, you can use two modules in parallel, such as the output to 30A, two modules can be used in parallel,The current per module can be adjusted to 15A.Working temperature: -40 to + 85 degrees (ambient temperature is too high, please enhance heat dissipation)Operating frequency: 150KHzConversion efficiency: up to 95% (efficiency and input and output voltage, current, pressure related)Overcurrent protection: Yes (with reduced flow adjustment, adjustable output current limit, current exceeds the current limit, the output current is automatically reduced to a minimum 5A, vary according to the nature of the load current will be.)Short circuit protection: Yes (input 20A fuse) double short circuit protection, the use of more security.Input reverse polarity protection: None, (if necessary, please enter the string into the diode)Output Counter filling: Yes, for charging plus blocking diode is not required.Installation: four 3mm screwsConnection: solderless terminals outputModule dimensions:116x52x15mmWeight: 300 g Package Included:1/5/10PC*1200W 20A DC Converter Boost Step-up Power Supply Module 8-60V to 12-80V
