Volt Polska SINUS PRO 2500 24/230V (1800W/2500VA) UPS

The SinusPRO 2500W 24V computer emergency power supply is a device designed to provide uninterrupted power to computers, servers, and computer systems. In the event of a power outage from the 230VAC mains or a photovoltaic system, the device switches to battery mode, allowing the system to continue operating without interruption and protecting against irreversible data loss.

Key Features:

• “OFF-GRID” power supply with unidirectional voltage (do not connect the inverter output to the electrical installation)

• Automatic Voltage Regulator (AVR) for mains stabilization

• Built-in mains charger for charging the connected battery

• Pure sine wave inverter 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) and reacts very flexibly to overloads, including the startup of pumps, compressors, and motors

• The inverter can also operate in UPS mode, ensuring practically uninterrupted and reliable operation of devices such as blowers, feeders, pumps, central heating systems, and automation

• LCD display showing the most important parameters

• Solid and compact housing

What devices can the SinusPRO 2500W 24V power?

• Central heating pumps and boilers
• Motors for automatic gates and elevators
• Refrigerators and freezers
• Air conditioners
• Consumer electronics such as TVs, consoles, speakers, etc.
• LED lighting
• Home automation and smart home devices
• Power tools such as drills, grinders, angle grinders, etc.
• Household appliances such as washing machines, microwave ovens, etc.

Why is it worth using the SinusPRO 2500W 24V power supply?

• Built with a highly efficient toroidal transformer
• Wide input frequency range with automatic 50/60Hz detection
• Full range of protections and alarms: overload, short circuit, overvoltage, undervoltage, and temperature protection
• LCD display providing information about the current operating status, including input and output voltage, battery voltage, and charging status

What makes the SinusPRO 2500W 24V stand out from other devices?

• The built-in pure sine wave inverter generates an output voltage with a sinusoidal waveform, identical to the voltage in the power grid. This makes it possible to power inductive devices (including power tools, air compressors, air conditioners, refrigerators, freezers, etc.).

⚠️ IMPORTANT! We recommend using dedicated AGM/Gel lead-acid batteries designed for buffer/cyclic operation and deep discharge. Connecting car batteries that are not designed for this type of operation may result in damage to the inverter and/or the battery. LiFePO4 batteries must also not be connected due to different charging/discharging characteristics compared to Sinus PRO E, W, and S series devices.
For use with LiFePO4 batteries, we recommend the VOLT Polska Sinus PRO ULTRA series.
