The MPL RTS-LI-1k5-3U-L is a rack-mounted UPS using Line Interactive technology with pure sine wave output in both mains and battery modes. It is designed to protect connected IT equipment from power interruptions, overloads, short circuits, overvoltage, and deep discharge. The 3U, 19-inch rack housing keeps the unit compact within standard cabinets.

The unit provides automatic voltage regulation, a 10 ms transfer time to battery, and auto-recovery when mains is restored. Communication is via USB (standard) or RS-232 (optional), supported by UPSmart software across Linux and Windows platforms.

Key Features

• Line Interactive technology with pure sine wave output in mains and battery modes
• 19-inch RACK housing — 3U / D6 form factor
• Auto-recovery after mains supply restoration
• Protection: anti-overload OPP, short circuit protection SCP, deep discharge protection
• Automatic battery charging; switches automatically to battery on mains failure
• Remote communication and self-diagnosis
• Input voltage: 230V; Output voltage: 230V / 50–60Hz
• Output sockets: 3 x IEC C13 and 3 x Schuko

Product Benefits

• Pure sine wave output in battery mode is compatible with sensitive power supplies in servers, switches, and medical equipment
• The 175Vac–290Vac input range handles significant mains voltage swings without switching to battery, reducing battery wear
• At 50% load the batteries provide approximately 5 minutes of runtime — sufficient for orderly shutdown procedures
• The noise level below 50 dB at 1 m keeps the unit suitable for office and open-plan environments
• UPSmart software supports Linux and all major Windows versions from 98 through Windows 10, enabling scheduled shutdowns and event alerts

Why You'll Love It

• The 3U rack form factor fits directly into standard 19-inch cabinets alongside your other rack equipment
• Six output sockets (3 x IEC C13 + 3 x Schuko) give flexibility to connect a mix of server and peripheral hardware
• The wide input range (175–290Vac) means the unit rarely switches to battery during typical voltage fluctuations, maximising battery lifespan
• Automatic charging while the UPS is off ensures the battery is always ready when needed
