They can bridge power failures or voltage fluctuations and supply voltage to the DC 24V bus for a certain period, which allows for a safe shut-down of the system. Expensive downtimes, long restart cycles and loss of data can be avoided. Nominal voltage Output current Buffer voltage Input current In times when the power supply provides sufficient voltages, the buffer module stores energy in the capacitors. In case of a mains voltage fault, this energy is released to the DC bus in a regulated process. The buffer modules are maintenance-free and have a similar lifetime expectancy as power supplies. No regular replacement of the capacitors is necessary as is required for battery based UPS systems. The wide temperature range from -40°C to +60°C makes the unit suitable for many applications. The buffer modules come in two versions which differ in the size of the installed capacitors.

□IfinenJSIOflJ UC-Series 24V, 15A, CAPACITOR-BASED BUFFER MODULES The output section of the buffer module is fully controlled and is equipped with an electronic current limitation. A current overloading of the buffer module cannot happen, independent of which sizes of power supplies are used on the input of the buffer module. The current limitation works in a switching mode which reduces the power losses and heat generation to a minimum. Output in normal mode: In normal mode (and also in charging mode), the output voltage is slightly lower as the input voltage. The output voltage follows the...
