Resonance Ltd.  provides upgrade options and battery replacement solutions for UPS products.

In today's increasingly technological devices require uninterruptible power supply and therefore its role is important.

Testing, calibration and maintenance - activities that ensure stability and continuity of quality power.

Preventive maintenance and testing are essential for long and trouble-free operation of uninterruptible power supply.

Self-testing of uninterruptible power supply is usually automatic and takes place in small intervals. Often self and self-calibration is made after the start of any UPS.

Testing the internal resistance of batteries is one of the most important parameters indicating the status and capacity. It is desirable that the inspection be carried out both at the individual level battery and block-level removable batteries, as sometimes only one block from the battery may be defective. This will change if a separate battery, the entire block of all batteries or a matter of decision of the organization operating the UPS.



An Uninterruptible Power Supply (UPS) is an important thing to have if you live in an area where power outages are at all common, especially if you run a mail/DNS/Web server that must be up 24/7.

Everyone is vulnerable to outages caused by storms and other natural phenomena and must protecting both of its software and hardware.

Uninterruptible Power Supplies does three things for you. First, it filters the power your machine sees, smoothing out spikes and voltage fluctuations that can stress or even damage your electronics. Secondly, it provides a certain amount of dwell time in the event your power goes out entirely — this can often get you through brownouts and short blackouts. Third, when the UPS is about to run out of power it can arrange a graceful shutdown of your computer so that no unpleasant things happen to your disk filesystems.

Here's what a UPS will do for you:

  • Absorb relatively small power surges.
  • Smooth out noisy power sources.
  • Continue to provide power to equipment during line sags.
  • Provide power for some time after a blackout has occurred.

In addition, some UPS or UPS/software combinations provide the following functions:

  • Automatic shutdown of equipment during long power outages.
  • Monitoring and logging of the status of the power supply.
  • Restart equipment after a long power outage.
  • Display the voltage currently on the line.
  • Provide alarms on certain error conditions.
