Smart UPS

We cover all aspects of project design, from studies and Design to Configuration, Testing.
We customised design solutions that are tailored to your needs and your production process.

The Smart-UPS is a series of enterprise-level uninterruptible power supplies (UPS) made by American Power Conversion (APC). With the exception of RT and SRT series, Smart-UPS units are line-interactive UPS systems, only running their inverters when the grid power is unavailable.

What do you need the DC UPS for?
Bridging: To bridge a mains failure so that your machines continue to run.

Shutdown Procedure
(Safe Shutdown)/Shutdown procedure (tB < MAX).

  • Secure shutdown from an IPC.
  • Tiered shutdown (Mixed loads + data management + error handling).

UPS500S – 2,5–20 kWs

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).

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.
  • Free SITOP Manager software tool for simple configuration and integration in PC-based systems.
