Technical FAQs 4

What are uninterruptible power supplies (UPS)?

Uninterruptible Power Supplies (UPS) play a crucial role in ensuring a continuous and reliable power supply for critical electronic devices. When it comes to UPS systems, there are two primary types: DC UPS and AC UPS.

How do I Choose an uninterruptible power supply for DC applications?

Our uninterruptible power supplies for DC applications provide reliable protection against supply interruptions. Select the appropriate DC UPS for your application. Our uninterruptible power supplies for AC applications provide a pure sine curve at the output. Select the ideal AC UPS and ensure superior system availability.

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.

Can I use a ups with a switch mode power supply?

You can also use a UPS together with a switch mode power supply to further increase your options. A DC-DC UPS is the optimum option for backing up devices with a DC input power supply. An AC-AC UPS is the optimum option for backing up devices with an AC input power supply. Mechanism
