SAI Salicru SPS 500 ONE BL IEC Line-Interactive 0,5 kVA 240 W

The Salicru SPS 500 ONE BL IEC is a Line-Interactive UPS in a compact tower format that delivers 0.5 kVA (240 W) of output power. Designed for home and small office use, it provides battery backup with a pseudo-sine wave inverter and overload protection. The unit includes automatic voltage regulation (AVR) to correct small voltage fluctuations without draining the battery, extending battery life. It also offers a USB Type-B communication port using the HID protocol for parameter configuration, controlled shutdown or hibernation of connected computers, and is compatible with Windows, Linux and Mac operating systems.

Advantages

The UPS provides uninterrupted power during outages to allow orderly shutdown of computer systems and protection against data loss and equipment damage. AVR corrects minor voltage variations automatically, reducing unnecessary battery cycling. USB HID communication enables integration with operating systems for automatic shutdown and monitoring. The compact tower design and four AC outlets allow easy placement and connection of multiple devices while keeping the unit relatively lightweight.

Suitable for

• Home desktop computers and peripherals
• Small office workstations and network devices
• Point-of-sale terminals and cash registers
• Router/modem and small network equipment

How to use

Place the UPS on a stable, flat surface with adequate ventilation and connect required equipment to the AC outlets. Plug the UPS into a grounded mains outlet and switch it on. For computer integration, connect the USB Type-B port to the computer and install compatible UPS monitoring software if automatic shutdown or advanced monitoring is needed. During normal mains operation the AVR will stabilise small voltage variations; on mains failure the unit supplies power from the battery to allow safe shutdown of connected devices.

Recommendations

Use the UPS to protect single workstations, home computers and small network devices. Avoid connecting high-power devices that exceed the 240 W rating. Test the battery periodically and replace it when capacity falls significantly; follow manufacturer instructions for disposal and replacement. Keep the unit in a dust-free environment and ensure the recharge time of about 6 hours after deep discharge.
