Protect your home and ensure energy security! 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 like furnaces and pumps deserve special attention. Therefore, it's worth having a backup power supply in case of a power outage. Home Backup Power Supply KEMOT backup power systems protect selected devices from power interruptions that may disrupt or interrupt their operation. Wondering which UPS to choose for your gas boiler, or perhaps you're interested in a UPS for a coal or pellet boiler? The KEMOT PROsinus series is ideal as a backup power supply for central heating pumps or pumps in fireplace installations, as well as induction motors or automation devices in installations using heat convectors and any devices that are extremely sensitive to the slightest changes in voltage waveform. Their advantage is a pure sinusoidal output voltage waveform (supplying loads), thanks to which the device ensures stable operation, preventing overheating of inductive loads. Together with a 12V battery, they constitute a complete guaranteed 230 VAC power supply. Home Backup Power Supply – Applications • Backup power for furnaces • Consumer electronics (TVs, tuners, hi-fi, DVD) • Household 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 backup power supply at home KEMOT backup power supplies have overload, short-circuit, and over/under voltage protection. This guarantees safe operation in your home. Three operating modes Backup 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. Backup power supply with constant phase The KEMOT backup power supply works with devices equipped with phase detection, such as some gas boiler models. The phase in our device is in a fixed position, regardless of whether it is powered from the mains or the battery. Backup power supply for furnace with battery To ensure the highest quality of operation of the KEMOT backup power supply, it is necessary to select an appropriate battery. Optimal battery selection can be made using the approximate formula: 100 W load = 10 A draw from the battery. A battery for powering the house is not included. To ensure the best operation of your backup power supply, choose a Rebel or Vipow brand battery. Clear LED display KEMOT PROSinus backup power supplies are equipped with a clear LED display that shows the current operating status of the device. On the display, you can check, among other things, the input and output voltage and frequency levels. Furthermore, you can quickly check the load level and battery charge level.
