Product information

Description

The KEMOT PROsinus-500 is a high-quality uninterruptible power supply and voltage converter engineered to provide a stable pure sine wave output. Designed to bridge the gap during power outages, this device converts 12V DC battery power into reliable 230V AC electricity. With a power capacity of 500VA and 300W, it ensures that connected equipment continues to operate smoothly without interruption, making it an essential component for maintaining home comfort and safety.

Advantages

The primary benefit of the KEMOT PROsinus-500 is its ability to produce a pure sine wave, which is identical to the electricity provided by standard wall outlets. This makes it perfectly safe for sensitive electronics that might otherwise be damaged by modified sine wave inverters. Additionally, the device features an integrated automatic battery charging function, allowing it to maintain the connected battery at optimal levels while grid power is available. Its compact design and efficient operation make it a versatile solution for various household power needs.

Suitable for

  • Central heating pumps and furnace controllers
  • Home security systems and surveillance cameras
  • Computers, routers, and networking equipment
  • Small household appliances and LED lighting

When it may not be suitable

This device is not intended for high-power appliances that exceed its 300W continuous output limit, such as electric kettles, heaters, or power tools. Attempting to draw more power than the rated capacity will trigger the overload protection and shut down the unit.

Key specifications

  • Output power: 500VA / 300W
  • Output waveform: Pure sine wave
  • Input voltage: 12V DC
  • Output voltage: 230V AC
  • Integrated battery charger: Yes

How to use

To use the KEMOT PROsinus-500, connect a compatible 12V external battery to the input terminals, ensuring correct polarity. Plug the device into a standard 230V wall socket to allow the internal charger to maintain the battery. Connect your electronic devices to the output socket on the unit. In the event of a power failure, the device will automatically switch to battery mode, providing continuous power to your connected equipment.

What to consider before purchase

  • Ensure your external 12V battery is in good condition and has sufficient capacity for your needs.
  • Verify that the total power consumption of your devices does not exceed 300W.
  • Check that the device is placed in a well-ventilated area to prevent overheating.

Usage recommendations

For optimal performance and longevity, use a deep-cycle battery specifically designed for UPS or solar applications. Regularly check the battery connections for corrosion and ensure the firmware or settings are appropriate for your specific battery type.
