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.
