Product description

UPS-1228-12 is a high efficiency UPS DC power supply module, designed forapplications where DC backup power needs. The module supports a wide input voltage range, lead-acid batteries, lithium ion, lithium polymer, lithium iron phosphate battery as a backup battery, has perfect chargingmanagement function, at the same time onboard automatic lifting pressureregulator circuit, DC power supply voltage can be provided directly to the device after. Switch between the input power and battery, the output voltageis stable, the work load is not affected.

The input power supply electricity to charge the battery module, power supply,while the output voltage regulator after equipment. When the input power supply module, automatically switch to battery power supply, power supplyand voltage to the equipment, the switching time is zero, does not affect the work load. The battery power supply, onboard MCU real-time monitoring ofthe voltage of the battery, when the battery is discharged to the undervoltage threshold voltage setting, automatically turns off the output power, into a low power sleep mode. Only to input power or battery voltage recovery to start the threshold voltage, the power supply will start.

Please note that the charging part of this module for the buck charging,voltage input power must be less than charging rechargeable batteries to charge high cut-off voltage 1V. For example, the battery is lead-acid battery 12V, the charging voltage is 13.8V, then the input power to 14.8V ~ 28V DC power supply, we can choose common 19V or 24V power adapter as input power.

Module with automatic lifting voltage regulator circuit, regardless of inputpower or battery voltage V, the output voltage can be adjusted from 3V to 28V.


The scope of application

Provide backup power for a single 12V power supply computer

Access control, security backup power supply

Backup power supply for industrial control system
