Technical FAQs 4

What is an AC ups & how does it work?

In an AC UPS, the incoming AC power is typically rectified to DC to charge a battery or a bank of batteries. During a power outage or disturbance, the stored DC power is then inverted back into AC power to provide a continuous and uninterrupted power supply to connected devices.

What is the difference between AC & DC UPS?

The primary difference between AC UPS and DC UPS lies in the type of electrical current they use and the way they handle power during normal operation and outages. Here are the key distinctions between the two: Type of Power Input AC UPS: Accepts and uses AC as the input power source.

What is an uninterruptible power supply (UPS)?

Uninterruptible Power Supplies, or UPS for short, are indispensable in guaranteeing a consistent and dependable power supply for vital electronic devices. When delving into UPS systems, two main categories emerge: DC UPS and AC UPS.

What is a DC UPS?

What does DC UPS mean? A DC UPS is a kind of uninterruptible power supply system that primarily relies on direct current (DC) as its power source. In a DC UPS setup, the incoming power is already in DC form and is used to charge a battery or a battery bank.
