Switching power supply 13.8V 5.4A SCP-75-12 UPS battery BACKUP

Switching power supply with 100-240V AC 50/60Hz input and 13.8V DC 5.4A output, ideal for powering cameras and video surveillance equipment, home automation systems, and low-voltage electronic devices. Switching technology ensures high conversion efficiency while ensuring low heat dissipation compared to traditional power supplies.

This power supply supports the installation of a 12V UPS lead-acid battery with FASTON connectors of various capacities to obtain a power supply with an integrated UPS Backup and capable of powering the connected devices even in the event of a blackout or power failure for a variable time depending on the capacity of the installed battery and the absorption of the load connected to the power supply.

Battery not included. You can request a quote for the supply of your preferred battery using the contact details, or it can be purchased separately.

BATTERY AH CALCULATION

To calculate the best battery capacity for your needs with this power supply, you need to perform this calculation:

Battery capacity (Ah) = load absorption (A) x time in hours without power supply (h)

For example, to power a load that draws 0.5A (500mA) for 14 hours in the absence of a 230V mains power supply, a 12V lead battery with a capacity of 7 Ah is required, i.e. a battery with the next highest commercial capacitive value: Lead 12V 7.2Ah.

To increase the capacity, it is possible to place several EQUAL batteries in parallel by adding their respective capacities.
