What is a UPS Used For?

A UPS (Uninterruptible Power Supply) provides the best means of protection against a variety of electrical problems and disturbances that can cause irreversible damage to electrical and computing devices.

There is a wide range of electrical events that are dangerous for computing systems and electrical equipment. For example:

• Voltage drops that can cause systems to crash
• Spikes/surges that occur over milliseconds and can burn out electronic components
• Power outages due to short circuits, overloads, weather, etc.

Additionally, UPS systems offer the ability to continue operating and provide power to the equipment connected to the system during a power outage.

Three Main Types of UPS Systems:

1. Interactive (Line Interactive):

   • Produces a sine wave output. This device operates by allowing the grid voltage to pass through to the consumer via the device while filtering and stabilizing the voltage.
   • In case of a power outage, a switch is activated that takes about 2-8 ms, and the inverter in the device converts the battery voltage to alternating current, backing up the consumer for a predetermined duration (usually between 5 to 30 minutes).
   • Uses: Workstations, home computers.

2. Interactive Pure Sine Wave (Interactive Sine Wave Line):

   • Similar to section 1, but with a pure sine wave output.
   • Uses: Basic laboratory equipment, non-critical servers, gaming computers, communication equipment.

3. On-Line:

   • Produces a pure sine wave output. This device is also known as double conversion online, where the input voltage is rectified and then converted back to alternating current, providing complete isolation between the electrical grid and the consumer without switching. This method offers the best power supply and protection.
   • Uses: Servers, critical equipment, valuable equipment, medical equipment, solutions for areas with frequent voltage disturbances, communication hubs, operation with generators, etc.

Guide to Buying a UPS: 7 Important Tips:

1. Define Your Needs: What equipment do you want to protect? What is the required backup time?
2. Choose the Type of UPS: Match the UPS type to your needs and the type of equipment.
3. UPS Capacity: Ensure that the capacity matches the power consumption of the connected equipment.
4. Backup Time: Select a suitable backup time according to your needs and applications.
5. Additional Protections: Make sure the UPS includes protections against power surges and other types of electrical disturbances.
6. Warranty: Choose a reliable manufacturer and supplier that offers generous warranties.
7. Service and Support: Ensure that you can receive professional technical support if needed.

A UPS is our insurance for servers and important equipment.

There is a wide range of UPS systems using different operating systems for computers and servers, with on-demand backup times and customization options available through Advice’s sales consultants without obligation at 03-9000920.

A quality UPS system should handle various electrical disturbances (over 60 measured electrical disturbances on an average day) and, of course, provide backup and continued operation during power outages.

Important Considerations When Purchasing a UPS System:

• The company should be a professional and established one in the field with a suitable service system.
• Warranty Period: More warranty years = higher reliability and quality / financial savings in maintenance.
• Battery Type: A quality battery will be replaced after a long time while providing better performance = financial savings.
• Surge Protection: Measured in joules; the higher the value, the lower the chance of damage to the equipment.
• Input Voltage Range: The wider the input voltage range, the less interruption the UPS will have even during voltage spikes and drops.
• The field of UPS systems is a professional one, and thorough market research is crucial before purchasing.
• Sometimes a negligible price difference compared to technology/quality ends up being more costly in the long run.

Advice Electronics is the first and only company in Israel to offer a 3-year warranty on electronics and a 2-year warranty on batteries for a wide range of UPS systems with surge protection rated at 600 joules or higher. The company has 30 years of experience and thousands of reliable UPS systems that provide protection and backup for computers, servers, medical equipment, laboratory equipment, and many other consumers.

Glossary of Terms in the UPS Field:

• Uninterruptible Power Supply (UPS): A system that provides uninterrupted voltage.
• Line Interactive: A system that works with stabilized input voltage that activates only during a voltage drop.
• USB/RS232: A common communication protocol interface between processors.
• On-Line: Systems that work online and operate with double conversion.
• Automatic Voltage Regulator (A.V.R.): A system for automatic voltage stabilization.
