SITOP PSE201U buffer module buffer time 100 ms to 10 s depending on load current The SITOP PSE201U buffer module bridges short-term power failures up to the range of seconds and ensures uninterrupted plant operation. This supplementary module can be used with all 24 V power supply units of the SITOP smart or SITOP modular product lines. The buffer module is equipped with maintenance-free capacitors as energy storage and automatically takes over the 24 V supply in the event of a power supply failure. Signaling of supply voltage gt; 20.5 V via LED on device. To extend the buffer time (max.10 s), up to 8 buffer modules can be connected in parallel. The SITOP DC UPS modules offer protection in case of long-term power failures. The maintenance-free DC UPS with capacitors supplies a reliable 24 V in the time range of minutes, and the DC UPS with battery modules in the time range of hours. Regardless of the industry or requirement: Siemens offers reliable and efficient power supplies for any plant.
