The Schneider Elektrotechnik AC-C-TEC2403-05, an advanced capacitor-buffered power supply, is equipped with a buffer module that can correspond with ultra-capacitors as energy storage inside the housing. For instances of interference of the DC-power supply, the capacitor’s energy is bound to be released. The product’s load is provided by the buffer module, unless it’s already ejected. The back-up time of the process relies on the current state of charge of capacitors and on the discharge current.
