KEMOT PROsinus-1000 Emergency Power Supply Unit – Pure Sine Wave Inverter with 12V Charging Function, 230V, 1000VA/700W

Emergency power supply unit with pure sine wave inverter and integrated 12V battery charger. The KEMOT PROsinus-1000 delivers clean, stable 230V AC power from a 12V DC battery, making it ideal for sensitive electronics during outages or off-grid use. Its UPS function automatically switches to battery power in under 4 ms, ensuring uninterrupted operation of connected devices.

Advantages

Pure sine wave output (<3% THD) safely powers inductive loads like motors, pumps, and compressors, as well as sensitive electronics. The built-in 10A charger maintains lead-acid batteries (AGM, Gel, Flooded) and supports automatic transfer between AC and battery modes. Active cooling and comprehensive protection (overload, short circuit, over/under voltage, over temperature) ensure reliable long-term operation. An LCD display provides real-time status of input/output voltage, battery level, and load.
