Service and repair of UPS power supplies in Wrocław

We service Online / Double Conversion, Line-Interactive and Offline / Standby UPS units — from small UPSs for computers and office equipment, through professional UPSs for server rooms, including 19” rack units, to larger industrial systems. We repair both single-phase and three-phase UPSs. We accept large and three-phase UPSs at our service centre and repair them there, without visiting the customer. UPSs above 10 kVA are quoted individually.

The cause may be, among other things, damaged batteries, power supply circuit, rectifier, converter, inverter, power section or control electronics. We identify the exact cause during the diagnosis.

Not always. The most common cause is worn-out batteries, but the problem may also lie in the charging circuit, battery connections, inverter or the UPS electronics.

The cause may be an overload, a problem with the inverter, the supply parameters, the control electronics or the bypass circuit itself. We establish the exact cause after the diagnosis.

Most often it means the batteries are worn out, but the signal may also indicate an overload, battery operation, overheating or a fault in the charging circuit. We establish the exact cause during the diagnosis.

Typical symptoms are a short backup time, a sudden shutdown after a power cut, a weak battery message or a problem switching to battery operation.

We can assess the batteries by, among other things, measuring their parameters and internal resistance and running suitable operation tests on the device.

Usually 3–5 years, depending on the quality of the batteries and the operating conditions. High temperature shortens their life the most — a UPS works best in a cool room (around 20–25°C), away from radiators and with its ventilation openings uncovered.

In systems made up of several or a dozen or more batteries, replacing the whole set is often recommended. The final decision depends on the age, condition and measurement results of the individual batteries.

Yes, as long as they have the voltage, capacity, technology, dimensions and operating parameters required by the UPS in question.

If the model requires calibration, a battery information reset or additional tests after the replacement, we carry out the necessary steps as part of the replacement service.

We repair, among other things, battery charging circuits, main boards and control electronics, measurement and protection circuits, displays and control panels, fans, AC and DC capacitors, as well as SNMP, USB and RS232 communication. We determine the scope of the repair after the diagnosis.

Yes. Depending on the design of the device, we repair inverters, rectifiers, PFC circuits and converters, replace MOSFET / IGBT power transistors, and repair Static Bypass circuits, relays and the components responsible for switching between mains, battery and bypass power.

We complete most repairs within 1–3 days of the quote being accepted. If we need parts that we do not have in stock, the repair may take longer — we let you know when we give you the quote. In urgent cases, where possible, we speed up the repair at no extra charge.

The price depends on the type of fault and the power rating of the UPS — the price list shows separate prices for UPSs up to 1 kVA, 1–3 kVA and 3–10 kVA. You will get the exact repair cost after the diagnosis, before any work starts. UPSs above 10 kVA are quoted individually.

The diagnosis is free if you decide to go ahead with the repair after receiving the quote. If you decide not to repair, we charge a diagnosis fee according to the price list — depending on the power rating of the UPS.

Yes. First we diagnose the device and give you the scope and cost of the repair. We carry out the repair once you have accepted the quote.

Yes. After the repair, we run tests appropriate to the work carried out. If a load test or calibration is needed to complete the repair properly, it is part of the repair and we do not charge for it again as a separate service.

We give a 6-month warranty on the repair carried out, and 12 months on new batteries fitted at our service centre.

If the same fault comes back during the warranty period, we diagnose and repair the device again free of charge.

In typical conditions, it is worth having an inspection at least once a year. With heavy use, high temperature, dust or critical infrastructure, inspections may be needed more often.

It may include cleaning the inside of the device, checking the connections, electronics, capacitors and fans, checking the batteries, measuring parameters, analysing errors and testing mains, battery and bypass operation.

Yes, we issue VAT invoices. For businesses, we also offer regular periodic UPS inspections and ongoing service support — we agree the scope and schedule individually. We carry out inspections and repairs at our service centre.

Yes, you can send a UPS to our service centre by courier from anywhere in Poland. Before sending it, switch the UPS off and disconnect it from the power supply, pack it in a sturdy box (ideally the original one) and secure it with filling so that it cannot move inside — the batteries make a UPS heavy. For large or heavy devices (e.g. rack units or units with battery modules), please contact us before sending. You can also bring the UPS to our service centre in person or order pickup and delivery according to the price list (the “Pickup and delivery” section).

It depends on the type of damage, the condition of the device, the availability of parts and the repair cost. After the diagnosis, we can assess whether the repair makes economic sense compared with replacing the device.
