DISCOVER THE STABILITY OF WORKING WITH QOLTEC'S 500VA PURE SINE WAVE UPSUninterrupted power supply for low-power devices such as monitoring systems, power tools, heaters, and many more for extended periodsThe Pure Sine Wave UPS boasts the highest class and is made of high-quality materials. It is reliable in the event of a mains power outage, automatically switching to battery mode to prevent power loss to connected devices, allowing them to continue operating.The Qoltec UPS combines many functions to ensure continuous power supply to devices such as: - power tools,- fans,- monitoring systems,- LED lighting,- gate drives,- CO heaters,- pumps.It will also find application in working with many other low-power devices requiring continuous power for extended periods. You may already envision the UPS Qoltec Pure Sine Wave 500VA 350W with a steady phase, perhaps in your basement, workshop, or garage, fulfilling its duty with a connected battery.PURE SINE WAVE - HIGHEST QUALITY AND DEVICE SAFETYStable, clean energy with a sinusoidal waveform for full device protectionQoltec's online UPS units provide stable, interference-free clean energy with a sinusoidal waveform. This ensures full protection for your devices, thanks to dual conversion, which first converts AC mains power to DC, then back to AC, ensuring the highest level of power quality and protection against potential network disturbances such as voltage drops, power outages, surges, and failures.HOW LINE INTERACTIVE UPS WORKSBuilt-in automatic voltage regulation circuit ensures constant voltage regulationThe Line Interactive UPS relies on a built-in AVR (Automatic Voltage Regulation) system. This means that the input voltage is automatically regulated. If there is a drop or increase in voltage, the AVR system adjusts it to a level close to the nominal value. The presence of such a solution in an uninterruptible power supply has a positive impact on the durability of the connected battery and provides a constant voltage to the connected device.COMPATIBILITY WITH ANY TYPE OF POWER SUPPLYLine interactive, pure sine wave, long backup time, 3-step charging current selection, and moreQoltec's 500VA UPS offers:- long backup time,- line-interactive - switches to battery mode during power outages, - high charging current,- pure sine wave – ensuring safety and compatibility with any type of power supply, - CPU-controlled modular design,- AVR function (Automatic Voltage Regulator),- protection against overload, short circuit, voltage drop, overload, battery discharge, overheating, and reverse battery connection, - powerful transformer with high capacity and specially designed circuit with high load capacity,- dual conversion – delivering stable power. - 3-step charging current selection, - effective heat dissipation,- two output sockets.STRAIGHTFORWARD AND READABLE – FOR YOUR CONVENIENCEIntegrated LCD display ensures intuitive operation and monitoring of UPS parametersThe built-in LED display ensures easy device management.
