Buffer Module 24V dc I/P 24V dc 20A O/P
Art: UF20.241
The buffer module is connected in parallel with the power supply unit's 24 V dc output and is changed with a capacitor bank. If the primary voltage of the power supply unit falls to zero and the output voltage falls to 22.5 V dc, the buffer module is automatically switched in and overcomes the power failure. The buffer module can supply 20 A/24 V dc for 200 ms; if the load current is lower, the time increases. When connecting two modules in parallel, the time is doubled up to 20 A, alternatively, up to 40 A power supply can be connected for 200 ms. There are two status inputs that indicate when the buffer module is ready to discharge and when it is active. Additionally, there is an input for disconnection of the module for safety circuits and service, for example. A LED on the front shows the status. The buffer module requires no maintenance in that it lacks a battery and fits all applications for which one wants to avoid stops due to temporary power failures. Available for both the Dimension and Silverline series.
