UPS Salicru SPS 500 ONE BL Line-Interactive 0.5 kVA 240 W

The Salicru SPS 500 ONE BL is a Line-Interactive UPS in a mini tower format that provides 0.5 kVA (240 W) of backup power and overload protection. It delivers a pseudo-sine wave inverter output and includes automatic voltage regulation (AVR) to correct small voltage fluctuations without using the battery, extending battery life. The unit offers USB (Type-B) communication with HID protocol for parameter configuration, safe shutdown or hibernation of connected computers and is compatible with Windows, Linux and Mac operating systems. The internal lead-calcium battery is designed for long service life and recharges in approximately 6 hours.

Advantages

The SPS 500 ONE BL combines compact tower design with Line-Interactive topology to provide reliable battery backup and surge protection for home and small office equipment. AVR reduces unnecessary battery use during minor voltage variations, while the USB HID interface enables straightforward UPS monitoring and controlled shutdowns across major operating systems. Two AC outlets and a lightweight 3.5 kg chassis make it easy to deploy where space is limited.

Suitable for

• Home desktop computers and workstations
• Small office equipment (modems, routers, VoIP phones)

How to use

Place the UPS on a flat, stable surface near the equipment to be protected. Connect critical devices to the AC outlets and link the UPS to a computer using the USB Type-B cable to enable communication and automatic shutdown functions. Configure shutdown parameters and monitoring using the operating system-compatible software or via the USB HID interface. Ensure the battery is fully charged before relying on backup power for extended outages.

Recommendations

For reliable operation, perform periodic battery tests and replace the battery according to the manufacturer’s guideline or when runtime noticeably decreases. Keep the UPS in a ventilated, dry environment away from direct heat sources and avoid overloading the unit beyond its 240 W rating.
