OFF LINE UPS

OFF LINE UPS

INTRODUCTION

In off-line UPS the inverter operates only when needed because in offline UPS voltage is supplied only when mains power fails to operate equipment. It provides constant voltage to equipment. In this UPS when switching from main power to battery power, known as transfer time, an off-line UPS stops providing power to the equipment for a few milliseconds (typically up to 4ms).
