SITOP 24 V power supplies can be expanded with a SITOP UPS500 uninterruptible DC power supply (DC UPS) for bridging short-term power failures in the order of minutes. In PC-based automation solutions, the highly capacitive double-layer capacitors of the SITOP UPS500 supply enough energy to safeguard operating and application data and close software applications in a defined manner. You can increase the buffer times using SITOP PSU501S expansion modules (up to 3).
The IP65 version SITOP UPS500P in long metal housing is ideally suited to distributed use.

•24 V buffering for a few minutes to allow data to be backed up and applications to be closed.
•Absolutely maintenance-free
•Long lifetime, even at high temperatures
•High ambient temperatures up to +60 °C
•Short charging times
•No ventilation is required since no gas is emitted
•Distributed applications possible without control cabinet
•Software tool, free of charge, for easy configuring and integrating in PC-based systems

The high-capacitance double-layer capacitors bridge power failures for a few minutes. The time is normally sufficient, for example, for the safe shutdown of PC-based automation systems. The USB interface and a free software tool enable easy communication with the PC.
The capacitors have an extremely long life even at high temperature, and can be used at ambient temperatures of up to 60 °C.
