The MPL RTS11-ON-2k0-2U is a rack-mounted uninterruptible power supply using On-Line True Sine wave technology, which means connected equipment always runs from the inverter — eliminating any transfer delay on mains failure. Rated at 2000VA/1800W, it is sized for small server rooms, network closets, and critical IT infrastructure.

The unit is controlled by a CPU microprocessor and includes automatic voltage regulation (AVR), automatic frequency selection, advanced battery management, and auto-recovery after power restoration. Communication is via USB (standard) or RS-232 (optional) with UPSmart software support.

Key Features

• On-Line True Sine wave topology — 0 ms transfer time (max 4 ms)
• CPU microprocessor control with automatic voltage regulation (AVR)
• Automatic frequency selection (50/60 Hz)
• Cold start capability — starts from battery without mains power
• Advanced battery management with automatic charging in OFF state
• Auto-recovery after mains restoration
• USB communication port standard; RS-232 optional
• 8 x IEC C13 output sockets
• Audible buzzer alarm

Product Benefits

• True On-Line double conversion eliminates any power conditioning gap — output voltage and frequency are fully decoupled from mains fluctuations
• AVR continuously corrects input voltages between 176Vac and 280Vac without switching to battery, extending battery life
• At 50% load the internal batteries provide approximately 9 minutes of runtime, giving adequate time for orderly shutdown
• Automatic startup diagnostics detect battery or inverter faults before they cause an unplanned outage
• UPSmart software on Linux and Windows (98 through Windows 10) enables shutdown scheduling and event logging

Why You'll Love It

• The 2U rack form factor integrates directly into standard 19-inch cabinets without dedicated floor space
• Four internal 12V/9Ah batteries are included — no separate battery purchase required
• Cold start means the UPS can power up equipment after a prolonged outage even before mains is restored
• The automatic battery charger keeps the pack topped up even when the UPS is switched off, so it is always ready
