KEMOT PROsinus-800 Emergency Power Supply Unit – Pure Sine Wave Inverter with 12V Charging Function, 230V, 800VA/500W

In a home office during a sudden power outage, the KEMOT PROsinus-800 keeps your computer, monitor, and router running smoothly. This line-interactive UPS with pure sine wave output delivers clean, stable 230V AC power, protecting sensitive electronics from harmful waveform distortions. Its built-in 12V charger maintains an external battery (50-200Ah recommended), ensuring backup power is always ready. With a transfer time of ≤4ms, your devices won't even notice the switch to battery mode.

Why choose it

Pure sine wave output ensures compatibility with all AC-powered devices, including those with active PFC power supplies, motors, and audio equipment. The integrated 12V charger simplifies setup—just connect a suitable lead-acid or AGM battery (not included) and you have a complete UPS solution. The clear LCD display provides real-time status at a glance, while comprehensive protection circuits safeguard both the inverter and connected loads.

Ideal use cases

• Home office backup for computers, routers, and peripherals
• Protection for sensitive electronics like TVs, gaming consoles, and audio systems
• Powering small appliances during outages (fans, lights, modems)
• Mobile power for camping or fieldwork with a 12V battery

Good to know

The PROsinus-800 requires an external 12V lead-acid or AGM battery (50-200Ah recommended) which is not included. Its line-interactive topology with automatic voltage regulation (AVR) stabilizes minor fluctuations without switching to battery, extending battery life. The fan cooling ensures reliable operation even under sustained loads.
