UPS (Uninterruptible Power Supply) service is a critical offering that ensures the reliability and longevity of a backup power system. A comprehensive service typically involves both proactive maintenance and reactive repairs. During a service visit, technicians perform a thorough inspection of the UPS unit and its battery bank, checking for any signs of wear, overheating, or loose connections. Key tasks include cleaning internal components, performing battery health tests to predict end-of-life, and testing the system's transfer switch to ensure it functions correctly during a power outage. In the Gurugram area, companies like UPS Service India and Anubhav Power & Controls provide these essential services, often offering annual maintenance contracts to help prevent unexpected failures and costly downtime for critical equipment.
