Dropouts in the control voltage may cause failures and data loss. This drove WAGO to develop its UPS charger/controller, capacitive buffer module and pure lead battery module as four powerful products that reliably stabilize control voltages up to a maximum 40 A.
WAGO’s UPS charger and controller uses a battery-based buffer solution, requiring only one charger/controller for large load currents up to 40 A. This solution enables faster battery charging via high charging currents that can be set in 1 to 4 A steps to properly suit battery capacity.
The new pure lead battery modules for the UPS are characterized by their wide operating temperature range of −40 to 60°C (−40 … 140°F) as well as their high current resistance: High charging currents of up to 4 A expedite charging. This means that the battery modules provide maximum reliability – and will do so for up to ten years.
WAGO’s capacitive buffer modules prevent short power failures. They also buffer 40 A load currents over 300 ms and 5 A currents up to 6.6 s. In addition, the modules prevent undefined states for PLC, HMI and IPC via hard shutdown when the buffer voltage drops below 20 VDC.
