Title (EN) UPS MAINTENANCE BYPASS SYSTEMS USING MODE SIGNALING
(FR) SYSTÈMES DE DÉRIVATION DE MAINTENANCE D'UNITÉ D'ALIMENTATION PERMANENTE UTILISANT UNE SIGNALISATION DE MODE
Abstract:
(EN) A maintenance bypass (MBP) system for an uninterruptible power supply (UPS) includes a first switch having at least three positions that provide different couplings of a power source, a load, a power input of a UPS and a power output of a UPS and including a first contact set configured to indicate at least one transition between positions of the at least three positions. The system further includes a second switch configured to enable transition of the first switch between at least two of the positions and including a second contact set configured to indicate actuation of the second switch. The first switch may include a rotary switch and the second switch may include a pushbutton switch.
(FR) La présente invention concerne un système de dérivation de maintenance (MBP) pour une unité d'alimentation permanente (UPS) qui comprend un premier commutateur ayant au moins trois positions qui permettent différents couplages d'une source d'alimentation, une charge, une entrée d'alimentation d'une UPS et une sortie de puissance d'une UPS et comprenant un premier ensemble de contacts configuré pour indiquer au moins une transition entre des positions des au moins trois positions. Le système comprend en outre un deuxième commutateur configuré pour permettre la transition du premier commutateur entre au moins deux des positions et comprenant un deuxième ensemble de contacts configuré pour indiquer l'actionnement du deuxième commutateur. Le premier commutateur peut comprendre un commutateur rotatif et le deuxième commutateur peut comprendre un commutateur à bouton-poussoir.
