ITEM NAME:1200W DC-DC Boost Converter Power Supply 8-60V 12V Step up to 12-83V 24V 48 Product Description Description: Features: Large heat sink design. Supports a wide input voltage 12-60V, 12- 83V wide adjustable output voltage, low dropout voltage. Specification: 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 dissipation(input, output pressure related, the greater the pressure the smaller the output current) Constant Range: 0.5-20A Working temperature: -40℃~85℃ Operating frequency: 150KHZ Conversion efficiency: up to 95% Overcurrent protection: Yes Short circuit protection: Yes Input reverse polarity protection: None Output Counter filling: Yes Installation: four 3mm screws Connection: solderless terminals output Product size: approx. 130 x 52 x 49mm/5.11 x 2.04 x 1.92'' Net Weight: approx. 258g Gross Weight: approx. 262g Note: 1. The input power supply voltage must be above 8V. 2. Do the input power supply switching power supply, the case load of the first connected input source and regulate voltage. Then pick up the load. (Must ensure that the switching power supply has been working), or regulate the first no-load voltage, then switch the power supply open the case. When the voltage is lower than 8V, the chip has not been working. It is easy to MOS tube breakdown. 3. When a constant voltage to constant-current mode have to ensure a constant voltage must be higher than the input voltage. 4. Please allow 1-3mm differs due to manual measurement. 5. Due to the different display and different light, the picture may not reflect the actual color of the item. Thanks for your understanding. Included: 1 x Converter Boost Power Supply Module.Large heat sink design. Then pick up the load. It is easy to MOS tube breakdown. Gross Weight: approx. Short circuit protection: Yes. Output Counter filling: Yes. Constant Range: 0.5-20A. Installation: four 3mm screws.
