SINUS PRO-500W 12V emergency power supply unit

TheVOLT SINUS PRO UPS 500W is a computer-assisted emergency power supply from the SINUS PRO series, combining high-performance pure sine wave DC/AC converters. In the event of a 230V mains or photovoltaic power failure, the device switches to battery mode, which allows for further operation of the system and protection against irretrievable data loss.

The feature that distinguishes sinus-type uninterruptible power supplies from simple regular AC/DC converters is the generation of purely sinusoidal alternating voltage at the output, identical to that of the mains. The device includes the pure sine wave DC/AC functions, UPS emergency switch, mains voltage stabiliser (AVR), battery charger (charger) and the necessary protection for the device work with the solar controller and photovoltaics. Thanks to the use of a colour display, the device allows you to monitor the most important operating parameters of the system. This UPS is a part of the line-interactive series.

Device characteristics

• The functions of DC/AC converter, UPS and automatic battery charger all in one device
• The toroidal transformer used in the inverter provides high efficiency and low idling current.
• The device is much more energy efficient than older constructions using transformers with with E-cores
• High-speed 32-bit microprocessor for accurate and trouble-free operation
• Intuitive and simple operation thanks to the colour LED display, which informs about the current status of the device (input and output voltage, battery status, charging, etc.)
• The inverter produces pure sine wave voltage at the output, which makes it possible to work with practically any kind of load
• High battery charging current (exact values in the table with technical specifications)
• Charge current can be changed with a button and the charger can be switched off
• Quick changeover from mains to UPS mode for uninterrupted operation connected devices
• Intelligent cooling fan control, depending on the actual device temperature and operating status of the inverter
• AC (mains) / SOLAR (battery) priority switch

• Normal working, the device is powered directly from a 230V BYPASS network
• Battery mode, lack of voltage on the mains, powering the devices with the battery
• Overheat, the connected devices are now disconnected
• Unusual, wrong battery voltage, MOSFET short-circuited or overheated
• Overload, the connected device use too much power
• Load indicator
• Battery charge indicator, it will flash during charging
• Input voltage
• Output voltage and frequency
