Features:This is a nonisolated DC power converter module with long service life.High power and stable output, it converts 1060VDC to 1297VDC.High quality components ensures high conversion efficiency, up to 97%.Designed with smart temperature control fan, which will automatically work when temperature reaches about 60, and stop when temperature drops below 60.Widely used for high power solar street lamp driving, various LED lighting CV driving, vehiclemounted and mobile device power supply, DIY adjustable CV CC power supply, solar power charging, and various batteries charging.Specification:Name: 1500W step up constant current moduleType: Nonisolated stepup module (BOOST)Input Voltage: DC10V to 60VInput Current: 10V30V input voltage, maximum current is 35A40A; 3160V input voltage, maximum current is 30A35AQuiescent Current: 15mA(when convert 12V to 20V, higher output voltage will increase quiescent current)Output Voltage: 1297V continuously adjustable (cannot be used to step down voltage)OutputCurrent: 22A (related to the input and output voltage difference, the greater voltage difference is, the smaller output current will be. please enhance heat dissipation when current is over 15A)Constant Current Range: 0.822A(+/0.3A)Reverse Input Protection: Yes (150A power MOS reverse protection)Input Low Voltage Protection: Yes (10V50V adjustable, selfrecovery)Operating Temperature: 40 to 85(if temperature is too high, please enhance heat dissipation)Frequency: 150KHzConversionEfficiency: 92% to 97% (Efficiency is related to input/output voltage, current and voltage difference. The smaller difference is, the higher efficiency will be)Input Over Current Protection: Yes (automatically protect when input is more than 40A, and power supply voltage will not increase)Short Circuit Protection: Yes (input 60A fuse) please operate carefully, try not to cause short circuit.Reverse Input Protection: Yes ((150A power MOS tube, can be connected reversely for long time)Installation Method: Four 3mm standoffsWiring Method: Terminal blocks (Please use large current copper wire)Output Power: Maximum Output Power = Input Voltage*30A(If input 12V, the maximum output power=12V*30A = 360W)(If input 24V, the maximum output power=24V*30A = 720W)Weight: 372g / 13.1oz (approx.)Package list:1 x ModuleNote:Please note that the fan of this product will be sent randomly, and make sure you will not mind before ordering.Instructions:Moduleoutput should not short circuit or measure current directly with multimeter short circuit, short circuit will burn out module.Under voltage adjustable range:DC10V50V (clockwise to increase, counterclockwise to reduce), firstly adjust undervoltage to the minimum, then adjust input voltage to required undervoltage protection value, slowly adjust undervoltage value clockwise to increase; when theundervoltage light is on, adjust counterclockwise of one circle, then power on again. Input undervoltage protection mainly used to prevent battery from overdischarging when input power source is battery. Low battery voltage will damage power module and battery. When input is switching power supply, it also need to set the low voltage protection.Constant voltage adjustable range:DC1297V(clockwise to increase, counterclockwise to reduce), first adjust voltage to the required voltage and then connected to the load.Constant current adjustable range:0.822A (clockwise to increase and counterclockwise to reduce), first disconnect load, then adjust output voltage to required voltage, adjust current to the minimum (counterclockwise turn CC potentiometer about 30 circles), connect an ammeter in series to the output, then slowly adjust current.(booster module cannot directly adjust current by short circuit)Input voltage should not be lower than 10V or higher than 60V, (when input voltage is lower than 12V, please properly reduce the load).Make sure the input voltage is at lease 2V lower than output voltage. Ifuse switching power supply or other secondary power supply, please makesure that power is 1.3 times greater or more than the power supply module's power.During over current or undervoltage protection, output will still have voltage that is close to the input voltage, protection means no boosting voltage..
