UPS SINUS PRO 500 E 12/230V (350/500W) 3SP050012E

Uninterruptible Power Supply (UPS) for a wide range of applications

The sinusPRO 500 E 12V UPS is a versatile device that provides uninterrupted power in the event of a mains power failure. It is suitable for both home installations – protecting central heating boilers, pumps, controllers – and professional applications, such as powering servers, computer sets or automatic gates. Thanks to the UPS function, it protects against data loss and equipment damage.

### Functionality and versatility in one device

This is not only a UPS, but also an advanced energy management system. The functions of a DC/AC converter with a clean sinusoidal waveform, an UPS switch, a network battery charger (rectifier) and a network voltage stabilizer (AVR) are combined in one device. A color display makes it easy to monitor operating parameters and device status. The "line-interactive" type power supply can reverse the voltage polarity at the output during switching to battery power.

### Pure sine wave – the key to compatibility

A distinguishing feature of this model is the generation of an output voltage with a sinusoidal waveform, identical to that in the power grid. This is crucial for the correct operation of inductive devices – power tools, pumps, air conditioners or refrigerators – which require stable and "clean" power. Unlike simpler converters that produce a rectangular waveform voltage, the sinusPRO 500 E ensures reliable operation of even the most sensitive equipment.

### Key features and parameters:

The sinusPRO 500 E 12V power supply is characterized by a momentary power of 500 VA and a continuous power of 350 W. It accepts an input voltage in the range of 170-270 VAC, and the output voltage in battery mode is 230 VAC ±1%, and in network mode with AVR – 216-245 VAC. The device works with 12 VDC batteries and offers a charging current of 10 A. The efficiency exceeds 92%, and the operating temperature range is between 0 and 40°C. The applied protections include protection against overload, overcharge and battery discharge.

**Important!** It is recommended to use dedicated AGM/Gel lead-acid batteries designed for buffer/cyclic operation and deep discharge with this power supply. Avoid connecting car or LiFePO4 batteries, as they may be damaged or not function properly with this model. For operation with LiFePO4 batteries, the Sinus PRO ULTRA series from VOLT Polska is recommended.
