Expert installation: Our team of highly skilled professionals performs precise and effective UPS capacitor replacements.
Preventive maintenance plans: Benefit from our customized capacitor UPS system service plans that maintain your system’s optimal health and extend its life span.

When Should UPS Capacitors Be Replaced?

Capacitors should be replaced every five to seven years, depending on the manufacturer’s recommendations and operating conditions. Capacitors operating under high temperatures or excessive load conditions may require more frequent replacements. Maintaining an optimal ambient temperature and proper airflow can help extend their life span.

Following any significant power surge or UPS system fault, capacitors should be inspected and possibly replaced. They might have sustained damage even if it’s not immediately evident.

Signs of a Faulty UPS Capacitor

Identifying a faulty capacitor early can prevent major issues and enhance the reliability of your UPS system. Here are some common signs that indicate UPS capacitor failure:

Oil leakage: The oil inside a capacitor removes air and helps regulate its internal temperature. When the oil leaks, the impedance and temperature increase, indicating that the component may fail soon.
Bulging and swelling: Excessive heat or internal fluid leaks can cause physical deformation of the capacitor. Swelling or bulging of the capacitor’s casing indicates internal damage.
Scorched wires: Over-current can lead to scorched or burned wires connected to the capacitor. This can be detected through thermal imaging and is a sign that the capacitor is not handling the electrical load properly.
Reduced capacitance: Like batteries, capacitors age and lose their ability to store a charge. A significant drop in capacitance is a clear sign that the capacitor is nearing the end of its service life.

Types of Capacitors We Can Replace

Nationwide Power offers expert replacement services for all types of capacitors.

Alternating Current (AC) Input Capacitors

AC input capacitors filter and smooth input voltage fluctuations, improving UPS efficiency and reducing stress on input components.

Direct Current (DC) Capacitors

Integrated within the rectifier section, DC capacitors smooth the rectified DC voltage coming from the AC input. They minimize the ripple current generated during the AC to DC conversion process, ensuring a clean and stable usable DC voltage.

AC Output Filter Capacitors

AC output filter capacitors are located at the UPS output stage to filter out pulse width modulation (PWM) frequencies and ensure a smooth final waveform.
