Description
48V 3kW Standalone Power Supply
Product Description
A Standalone DC Power Supply converts alternating current (AC) to direct current (DC) and provides the DC power necessaryto power on DC Loads and charge batteries. With a focus on continuously improving the total cost of ownership, Best PlusPower’s Standalone DC Power Supply, combined with advanced technology, help to reduce both capital and operationalexpenditure. Our Standalone DC Power Supply’s boast excellent power density while fulfilling space and weightrequirements. They leave plenty of room for other equipmentand create savings in packaging and transportation costs. Inaddition, their high efficiency lowers total energy consumptionand reduces carbon footprint.
The Standalone DC Power Supply has a wide input voltage range,which can work normally with 90VAC-280VAC input. The StandaloneDC Power Supply has input over-voltage and under-voltage protection,output short circuit protection, output overvoltage protection,over-current protection, over-temperature protection, battery charge and discharge management and RS485communication functions, and adopts natural cooling. The entire power supply is strictly designed according to safetyregulations and meets the safety standards for information technology equipment.The standalone DC power supply has different of mount type, includes wall mount and pole mount, according to theinstallation environments.
