SINUS PRO 500 W 12/230V (300/500W) EMERGENCY POWER SUPPLY

The sinusPRO 500W 12V computer UPS is a device designed for uninterruptible power supply to computers, servers, and computer systems. In case of a power outage from the 230VAC grid or photovoltaics, the device switches to battery operation mode, allowing the system to continue working without interruption and protecting against irreversible data loss.
Key features:
“OFF-GRID” type power supply with unidirectional voltage (do not connect the converter output to the electrical installation)
Automatic network voltage stabilizer AVR
Mains charger for charging the connected battery
Pure SINUS type converter based on a toroidal transformer
The built-in toroidal transformer compensates for different reactive power of receivers (capacitive, inductive, and resistive loads can be combined), it reacts very flexibly to overloads, e.g., starting pumps, compressors, motors
The converter can operate in UPS mode, ensuring practically uninterrupted and trouble-free operation of, for example, blowers, feeders, pumps, central heating systems, automation, etc.
LCD display with key parameters
Robust and compact housing

What devices does the SinusPRO 500W 12V power?
- CO pumps and furnaces
- Motors for automatic gates and lifts
- Refrigerators, freezers
- Air conditioners
- RTV devices, e.g., televisions, consoles, speakers, etc.
- LED lighting
- Home automation and smart home devices
- Power tools, e.g., drills, grinders, angle grinders, etc.
- Home appliances, e.g., washing machines, microwaves, etc.

Why is it worth using the SinusPRO 500W 12V power supply?
- Design based on an efficient toroidal transformer
- Wide input frequency range, automatic 50/60Hz detection
- Full range of protections and alarms: overload, short circuit, over and under voltage protection, temperature protection
- LCD display, showing the current operating status of the device, including input and output voltage, battery voltage and charge

What distinguishes the SinusPRO 500W 12V power supply from other devices?
- The built-in pure SINUS converter produces a voltage with a “sinusoidal waveform” at the output, identical to that in the power grid. Thanks to this, it can power inductive devices (e.g., power tools, air compressors, air conditioners, refrigerators, freezers, etc.).

For operation with LiFePO4 batteries, we recommend using the Sinus PRO ULTRA series from VOLT Polska.

IMPORTANT! We recommend using dedicated AGM/Gel lead-acid batteries, which are suitable for buffer/cyclic operation and deep discharge. Connecting car batteries, which are not adapted for such operation, to the converter may result in damage to the converter/battery. Also, do not connect LiFePO4 batteries, due to a different charging/discharging characteristic than what the Sinus PRO E, W, S power supply offers.
