UPS Integrated Power Supply Operation
The three general categories of modern UPS systems are on-line, line-interactive and standby: • An online UPS uses a "double conversion" method of accepting AC input, to DC for passing through the (or battery strings), then inverting back to 120 V/230 V AC for powering the protected equipment. A UPS system serves as a bridge to maintain power supply, preventing interruptions that could disrupt operations or cause data loss. The core value of an Uninterruptible Power Supply (UPS) is "Energy storage during normal operation + Voltage regulation, seamless switching to battery power when the mains supply fails". Factors such as the rising trend towards the internet of things (IoT) and smart buildings, a growing number of datacenters across the globe, virtualization, and cloud.

What is dual power supply for relay protection
A self or dual-powered supply is often used in the design MCCBs or ACBs with an electric trip unit circuit. In this reference design the rectified input charges the capacitor to generate the output voltage. The regulated DC output voltage is set by a Zener Diode and a MOSFET shunt regulator. The 7SR46 dual powered protection relay is to be showcased at Enlit Europe, taking place in Frankfurt from November 29 to December 1. Due to their often remote location, secondary substations do not always have a battery to provide power to electronic equipment such as protection relays. Electronic trip units are true RMS sensing-over-current trip devices, requiring no external supply for their basic functioning.
