What is an uninterruptible power supply?
Uninterruptible power supplies or UPSs are battery chargers consisting of a combination of convertors, switches and energy storage devices (such as batteries), constituting a power system for maintaining continuity of load power in case of input power failure. 10 CFR 430 Appendix Y 2.27.
What are the standards relating to ups?
The question of standards relating to UPSs involves many aspects. There are safety, EMC compliance and performance considerations for the UPS equipment itself, and limitations for the equipment's impact on the power network. Lead-acid batteries have their own regulations relating to selecting, safe operation, testing, maintenance and replacement.
Does the ups comply with en50171 standards?
The UPS is also required to comply with the EN50171 standard in the specific case of protecting safety equipment, in addition to complying with the 62040 series standards. This standard specifies the general requirements for independent centralized power supply systems for safety equipment.
Is safety a mandatory requirement for UPS?
Ensuring the safety of service personnel is a mandatory requirement for UPS equipment and installations. Safety must be designed in to UPS systems; the only question is how to implement the safety design to achieve the maximum additional benefits in the form of improved system level resiliency.
