Specification: Brand new Module Properties: non-isolated step-up module (BOOST) Input voltage: 8-60V Input Current: 20A Quiescent current: 15mA (12V liter 20V, the output voltage, the higher the current will increase too quiet) Output voltage: 12-80V continuously adjustable Output Current: 20A MAX Over 15A, please enhance heat diipation (input, output preure related, the greater the preure the smaller the output current) Constant Range: 0.5-20A Output 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 = 1200W If 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 diipation) Operating frequency: 150KHz Conversion efficiency: up to 95% (efficiency and input and output voltage, current, preure 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 neceary, please enter the string into the diode) Output Counter filling: Yes, for charging plus blocking diode is not required Installation: four 3mm screws Connection: solderle terminals output Module dimensions: approx. 130x 52 x 15mm Package included: 1 x step-up power supply module Note: Please allow 1-5mm errors due to manual measurement Item color displayed in photos may be showing slightly different on your computer monitor since monitors are not calibrated same
