The Buffer modul UF 40 is an additional device for regulated 24 V DC power supplies, which can be used for different purposes:- Delivery of direct current for bridging from failures of the DC voltage supply system. Extension of the power outage bridging time after a failure of the supply voltage.- Short-term delivery of an additional peak current, the above the rated current of the power supply.It is maintenance-free electrolytic capacitors to store energy, which even in ambient temperatures of up to +70 °C can be used.For the buffer module is not a control wiring is required.It can be connected to any point in parallel to the load circuit can be added.Buffer modules can be connected in parallel in addition to provide more power or the power outage bridging time to increase.This text is machine translated.
