Technical support is an important element of our business. We offer help to everyone: it does not matter whether you are our customer or not. Fill out the request form, describe the problem, and we will try to help you. We will call you back. We are familiar with virtually all UPSs made by APC, SILCON and many others. Having a problem with the power supply? Want to repair your UPS? Don't know what criteria to follow when buying a new UPS? Contact us. Before replacing the batteries yourself, ask us what to pay attention to. Remember: better to ask the way than go astray.
