UPS 500 - Capacitor range

In many PC-based automation solutions, serious damage from a power failure can be prevented by bringing the plant to a defined state. It generally takes about one minute to back up the operating data necessary for this purpose and the subsequent controlled shutdown of the PC. The SITOP UPS500’s double-layer capacitors provide sufficient power for this to be accomplished.

Bridging power failures for a period of minutes – with a SITOP DC UPS with capacitors


In many PC-based automation solutions, serious damage from a power failure can be prevented by bringing the plant to a defined state. It generally takes about one minute to back up the operating data necessary for this purpose and the subsequent controlled shutdown of the PC. The SITOP UPS500’s double-layer capacitors provide sufficient power for this to be accomplished.


Powerful, totally maintenance-free, and usable in a variety of applications


The high-capacitance, double-layer capacitors (Ultracaps) store sufficient energy to shut down PC-based systems safely. Fast charging times ensure that buffering is available quickly once power is restored. Communication with the automation computer is easily implemented via the device’s USB interface.

And in terms of maintenance, SITOP DC UPSs leave nothing to be desired: even at a high ambient temperature, the capacitors have an extremely long service life. Because no maintenance or replacement of the energy storage unit is required, the SITOP UPS500 pays for itself in a short time. And because the capacitors don’t emit any gas, no ventilation of the control cabinet is required.

Whether for use inside or outside a control cabinet – SITOP offers you the right device version. The buffering time of the SITOP UPS500S for DIN rail mounting can be extended by adding expansion modules.
