Protect your home and ensure energy security! KEMOT PROsinus-500 500 VA / 300 W Backup Power Supply • 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 are particularly important. 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 disruptions that may disrupt or interrupt their operation. Are you 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 e.g., automation devices in installations using heat convectors and any devices particularly sensitive to the smallest changes in voltage waveform. Their advantage is the 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 supply for boilers • Consumer electronics (TVs, tuners, hi-fi, DVD) • Household appliances (refrigerators, blenders) • Power tools (drills, grinders) • Charger power supply (smartphones, tablets, phones, laptops) • Pumps, compressors (water, heating, air conditioners) • Office equipment (fax machines, computers, monitors) Safe backup power supply at home KEMOT backup power supplies have overload, short-circuit, overvoltage and undervoltage protection. This guarantees safe operation in your home. Three operating modes Backup power supply mode with charging function, converts 12V DC voltage from an external battery to 230V AC voltage and recharges the external battery. Rectifier mode recharges the external battery. Inverter mode converts 12V DC voltage from the battery to 230V AC voltage. 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 socket or the battery. Backup power supply for boiler with battery To ensure the highest quality of operation of the KEMOT backup power supply, you should select an appropriate battery. The optimal battery can be selected using the approximate formula: 100 W load = 10 A draw from the battery. The battery for home power supply is not included in the set. To ensure the best performance 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 indicates the current operating status of the device. On the display you can check, among other things, the input and output voltage and frequency levels. Moreover, you can quickly check the load level and battery charge level.
