PS Service, Repair, and maintenance are crucial for ensuring a reliable backup power supply. Proactive maintenance involves routine checks like testing battery health, cleaning internal components to prevent overheating, and inspecting connections. Repair services are reactive, focusing on diagnosing and fixing failures by replacing faulty parts such as batteries, capacitors, or circuit boards. This combined approach ensures the UPS operates efficiently during a power outage, minimizes unexpected downtime, and significantly extends its overall lifespan.
