Safe-Swap Modular Architecture Safe-swap, is a term used to refer to hot insertion and removal of modules from a host system without removing power. In a redundant Power Protection System Safe-swap is achieved only if a faulty module may be replaced without interrupting the power to the load (application) and w/o having to transfer the load (application) to the raw mains (by-pass). Employing appropriate hot swap techniques highly available power protection systems with ease of scaling and easy fault recovery can be created. 27 March 2011 DPA UPScale

Safe-Swap modules The DPA UPScaleTM Modules are fully independent and are composed of all major hardware and firmware building blocks: CPU (Central Processing Unit) All power circuits (rectifier, inverter, battery charger) Static switch and static switch control Power Management Control Panel In-built Display Static Switch Control unit Display Rectifier Booster Inverter Battery 27 March 2011 DPA UPScale
