Product Introduction
Features:
1. Input voltage = equipment operating voltage = battery charging voltage = battery full voltage
2.Utilizing the working voltage on the lithium battery 0 differential pressure complete full, very suitable for electronic professionals
3. Ordinary switching power supply can be charged, comes with a constant current circuit, does not require a special charger for lithium batteries
4.0 switching time, seamless switching, this product is the true meaning of the uninterruptible UPS
5. Comes with charging status display, simple and intuitive, very suitable for product matching
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%!
Parameter:
Charging red light, full off
Capacity: Battery capacity: 3*3.7V*3400mah=37 watt-hours (batteries user-provided)
Rated output power: 12V2A=24W
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.
Battery type: 3.7V flat 18650 battery
Charger type: built-in 0.4A current limiting module, can use 12-13V power supply charging, 12.7V is recommended.
Charging power: 12V0.4A=4.8W; input power>=(load power+5W)
Protection circuit parameters: overcharge protection 4.25V * 3; low voltage protection 2.75V * 3; overcurrent detection voltage 0.1V +-0.025V
Using temperature range: -20~60℃
DC interface standard: DC5.5*2.1mm (inside positive and outside negative)
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
Package include:
UPS battery box * 1（Not included Battery）
Wire *1
