Custom Order Type Uninterruptible Power Supply Device 'REQSTAR-CS'

Custom Order Type Uninterruptible Power Supply Device 'REQSTAR-CS'

DC/AC type, single-phase output model. Typically used in combination with a DC power supply.

"REQSTAR-CS" is a custom-order type of AC uninterruptible power supply (UPS) that operates on a direct current (DC) input. Since it requires DC power for input, it is typically used in combination with a DC power supply. The DC power supply converts three-phase AC from commercial power sources into DC power using a rectifier, supplying the necessary power to DC loads while charging a battery to prepare for any accidents with the commercial power source. The DC/AC inverter utilizes this DC power as input and converts it back into AC power to supply AC loads. Additionally, during a power outage, it converts direct power from the battery into AC power to supply AC loads. 【Features】 ■ DC/AC type, single-phase output Commercial synchronous constant inverter power supply method ■ Output capacity: 1–30 kVA Output voltage: 100V, 105V, or 110V ■ Standard equipped with an intelligent panel ■ Ideal coupling with computers ■ Flexible response ★ Yamato Kiko provides careful support from equipment installation to after-sales service, ensuring you can use it with peace of mind even after installation. *For more details, please refer to the PDF materials or feel free to contact us.
