Input voltage = equipment operating voltage = battery charging voltage = battery full voltage<br />2.Utilizing the working voltage on the lithium battery 0 differential pressure complete full, very suitable for electronic professionals<br />3. Ordinary switching power supply can be charged, comes with a constant current circuit, does not require a special charger for lithium batteries<br />4.0 switching time, seamless switching, this product is the true meaning of the uninterruptible UPS<br />5. Comes with charging status display, simple and intuitive, very suitable for product matching<br />6. High efficiency = (11.1V-0.3V)/11.1V*100%=97.3%; the higher the voltage of the battery series discharge efficiency will be infinitely close to 100%!</p> <p>Parameter:<br />Charging red light, full off<br />Capacity: Battery capacity: 3*3.7V*3400mah=37 watt-hours (batteries user-provided)<br />Rated output power: 12V2A=24W<br />Whether voltage stabilization: not voltage stabilization, 3 batteries in series direct output, full 12.6V, low voltage protection 8V, voltage increases or decreases with the amount of electricity Application type: for unattended, need to automatically charge and discharge management scenarios, fiber optic cats, routers, monitoring, fish tank pumps, etc.<br />Battery type: 3.7V flat 18650 battery<br />Charger type: built-in 0.4A current limiting module, can use 12-13V power supply charging, 12.7V is recommended.<br />Charging power: 12V0.4A=4.8W; input power&gt;=(load power+5W)<br />Protection circuit parameters: overcharge protection 4.25V * 3; low voltage protection 2.75V * 3; overcurrent detection voltage 0.1V +-0.025V<br />Using temperature range: -20~60℃<br />DC interface standard: DC5.5*2.1mm (inside positive and outside negative)<br />Warm tips: UPS function protection board do not do short-circuit protection test, may break through the diode. When the diode is broken down only after the short-circuit protection will be generated</p> <p>Package include:<br />UPS battery box * 1<br />Wire *1<br /></p></div></div>
