Protect your home and ensure energy security! KEMOT PROsinus 500 Emergency Power Supply 500 VA / 300 W Rated power: 300 W Battery type: 12 V DC Input voltage: 190 - 260 V AC Output voltage: 230 V AC +/-5% Output voltage waveform: pure sine wave Battery charging current: max. 10 A Switching time: < 4 ms Many homes have devices that make our lives easier but require constant power. In winter, heating systems, pumps, and other installations deserve special attention. Therefore, in case of a power outage, it's worth having a backup power supply. Home Backup Power KEMOT backup power systems protect selected devices from power disruptions that could disrupt or interrupt their operation. Considering a UPS for your gas, pellet, or coal boiler? The KEMOT PROsinus series is perfect for backup power for heating pumps, fireplace installations, induction motors, and devices sensitive to voltage fluctuations. The pure sine wave output ensures stable operation, preventing overheating of inductive loads. With a 12V battery, it's a complete guaranteed 230 VAC power supply. Home Emergency Power Supply - Applications: Backup power for furnaces AV equipment (TVs, tuners, hi-fi, DVD) Home appliances (refrigerators, blenders) Power tools (drills, grinders) Charging power supplies (smartphones, tablets, phones, laptops) Pumps, compressors (water, heat, air conditioners) Office equipment (fax machines, computers, monitors) Safe emergency power at home KEMOT emergency power supplies have overload, short-circuit, overvoltage, and undervoltage protection, ensuring safe operation in your home. Three operating modes: Emergency power supply mode with charging function converts 12V DC from an external battery to 230V AC and recharges the external battery. Rectifier mode recharges the external battery. Inverter mode converts 12V DC from the battery to 230V AC. Emergency power supply with constant phase The KEMOT emergency power supply works with devices equipped with phase detection, such as some gas furnace models. The phase in our device is in a fixed position, regardless of whether it is powered from the mains or the battery. Emergency power supply for furnace with battery For optimal performance of the KEMOT emergency power supply, select an appropriate battery. Use the approximate formula: 100 W load = 10 A draw from the battery. Battery for home power supply is not included. For best performance, choose a Rebel or Vipow battery. Clear LED display KEMOT PROSinus emergency power supplies have a clear LED display showing the device's operating status. You can check input and output voltage, frequency, load level, and battery charge level.
