Variable frequency uninterruptible power supply

What is an uninterruptible power supply?

Uninterruptible power supplies provide power to critical loads in the event of a power failure. Unlike emergency generators, UPS systems provide power immediately, but only for a short period of a few minutes – until a backup power supply comes online or until the load completes its shutdown sequence.

How can power quality data be used to optimize VFD & ups performance?

Technicians and engineers, working together with manufacturers, can use the observed power quality data to meet the ultimate goal: maximize VFD and UPS performance. Monitoring power quality parameters in a variable frequency drive or uninterruptible power supply, can help to maximize performance.

What is a 15 kVA 3 phase uninterruptible power supply?

15 kVA 3 Phase Uninterruptible Power Supply UPS Online Type UPS-5KVA to 200KVA Dimension (W×D×H)mm: 1000×800×2260 (1or2 cabinet) Weight: 2300kg In the event of an AC power failure, the UPS will automatically transfer to battery power and continue to provide power without any interruption for the full amount of time you select.

Do VFDs & ups have power quality issues?

VFDs and UPS systems are susceptible to power quality issues from the line power that supplies them, and they also produces harmonic currents that are reflected back into the distribution system. The best practice is to monitor power quality before installation, to verify the supplied power to the equipment will meet manufacturer's specifications.
