Product Description

Customer First is our aim, sincerely welcome new and old customers  letter,we are ready to serve you!Our advantage is: a good reputation, good price, good quality Direct supply of inventory, fast delivery.   

 

UPS-0528-11 is a DC on a lithium battery, lead-acid battery charging and the design of the UPS power module. When the input DC power supply, the output voltage is the input voltage. When the input DC power supply (or below the battery voltage) is powered by the battery, the battery voltage output =, seamless handoff, realize uninterrupted power supply function. Module output is not constant, the output voltage will vary with the battery voltage (input voltage) changes.

 

Does not support the 220V AC input

 

Product features

 

The input supply voltage range: 5 ~ 28V dc. Please ensure that the input supply voltage is higher than the charging battery cut-off voltage of 1V, otherwise not charge.

 

The maximum input current: 15A, load current and charging current is greater than 15A, the charge current will be reduced, so that the input current total of not more than 15A

 

The maximum switching current (output): 15A

 

Power supply switching time: seamless handoff. Input power down automatically switches to the battery output, and no switching time. When the input voltage is restored, restored automatically to the input power supply

 

The output does not have the voltage stabilizing function. The output voltage of the voltage stabilizing need, please the other module

 

No-load input current: 30mA (not connected with the battery and load)

 

Battery powered the no-load current: 100uA (input power, output no-load)

 

Rechargeable battery type: lithium battery (1 ~ 6 Series), lead-acid batteries (6V, 12V)

 

Charging mode: High Efficiency Synchronous Step-Down charging, the charging efficiency higher than 95%

 

Charging stages: trickle charge (for had put the battery), constant current, constant voltage, full stop, prevent overcharge. For the excessive discharge battery using small current charge to activate the battery, and then to the current charge

 

Charging voltage: adjustable (must be 1V lower than the input voltage), onboard multi ring precision potentiometer adjustment

 

The charging current: 0.5-8A adjustable, the default delivery 2A. Onboard multi ring precision potentiometer adjustment

 

Charging cut-off current: 0.3-1A adjustable, the default delivery 0.3A. Onboard multi ring precision potentiometer adjustment

 

Powered by battery input and output isolation, electrical feedback to the input without battery

 

Optional battery undervoltage protection and the power indication module

 

Working temperature: 20 ~ +85 degree

 

 

Pin definition:

 

1:Vout, output positive, with power load

 

2:GND, output, with power load

 

3:GND, the input, the input power supply negative

 

4:Vin+, the input cathode, the anode input power

 

5:Bat-, connected with the cathode of the cell

 

6:Bat+, is connected with the battery anode

 

Potentiometer:

 

VR1: charging cut-off current regulating potentiometer

 

VR2: charging voltage adjustment potentiometer

 

VR3: the charging current regulating potentiometer

 

The indicating lamp:

 

D1: green input power indicator. The input power supply is normal light, the input power is too low (and battery voltage differential pressure within 1V) when the input power is removed or flicker, than the battery voltage is low arc.

 

D2: dual color charge indicator lamp. When charging the green light, red light is bright. The input power is removed or not connected with the battery not bright
