2PCS 3A 30W DC-DC Boost Buck Adjustable Step Up Down Power Converter M Description: 30W high power wide voltage automatic buck module performance than LM259, LM2577 Output voltage can be higher or lower than the input voltage is more flexible Product Performance Description: Weight: 12g Appearance Size: 48 * 26 * 13mm (L * W * H) Input voltage range: 5.0-25V Output voltage range: 0.5V-25V (Output voltage can be higher than can be lower than the input voltage, but follow the principle of conservation of energy) Continuous output current: 3A (max) long working hours within please ensure 2A Continuous Input Current: 3A (max) long working hours within please ensure 2A Input / Output Power: 30W (max) Input / Output Current: rated conditions of calculation of the input / output current based on power conservation (Uin * Iin * efficiency = Uout * Iout) Instructions and precautions: IN +: Enter positive IN-: Input Negative OUT: Output + OUT-: output negative Enabling switch: Disconnect shorting cap module stop output. • No input reverse polarity protection, reverse will burn, please note polarity when in use. • Output short circuit module will automatically stop output, re-plug the enable switch shorting cap can be restored. • Module at no load and off load easily start momentarily output voltage exceeds a preset voltage, it is not suitable for voltage sensitive equipment. Note that the input is negative, then the wrong direct damage Common voltage data test: Boost Efficiency Buck Efficiency 5.0V turn 12V / 1A transfer efficiency 86.3% 5V 3.3V / 3A efficiency of 74.2% 7.4V turn 12V / 1A efficiency of 88.7% 12V turn 5V / 3A efficiency of 83.8% 12V switch 18V / 1A efficiency of 88.3% 24V switch 12V / 2A efficiency of 86.4% 18V switch 24V / 1A efficiency of 87.3% 24V switch 18V / 2A efficiency of 87.6% Buck Mode Efficiency 12V switch 12V / 3A transfer efficiency 87.4% 5V 5V / 2A efficiency of 81.4% Package: 2 x 3A 30W DC-DC Boost Buck adjustable step up down Power Converter Payment Shipping Refund We accept PayPal only.
