SITOP UPS1600
SITOP UPS1600 is Siemens' DC UPS branch for control systems that need short-term ride-through or buffered 24 VDC continuity when the incoming supply drops out, rather than just a primary regulated power supply. Compared with PSU6200 and PSU8200, UPS1600 is not the branch for creating the base 24 VDC supply; it is the branch for maintaining that control voltage during interruptions or brownout events. Keep it out of the decision if the cabinet only needs a standard SITOP supply and no backup-energy function is required. Keep this family in scope when the panel already points to SITOP power hardware and the remaining question is whether control power must survive mains disturbance or shutdown events. Read the product list by required backup role, supported load, and the intended pairing with the primary SITOP supply and storage elements.
