SITOP UPS500S Maintenance free uninterruptible power supply with USB interface Basic device 2.5 kWs input: 24 V DC output: 24 V DC/15 A degree of protection IP20 *Ex approval no longer available* The SITOP UPS500S with 100% maintenance-free capacitors is the optimal addition to all 24 V power supplies. It provides buffering for brief power failures over minutes. The time is generally sufficient, for example, to safely shut down PC-based automation systems or to visualize and archive operating data when extended power failures occur. The USB interface and a free software tool enable easy communication with the PC. The capacitors themselves have a very long service life even at very high temperatures and can be used in ambient temperatures up to 60 .C. No maintenance or replacement of the energy storage unit is necessary, which means that the DC UPS pays for itself after just a short time. And because the capacitors emit no gas, there is no need for control cabinet air extraction. Short charging times quickly restore the buffer readiness after a power failure. The UPS500S for rail mounting can be expanded with SITOP PSU501S expansion modules (maximum of 3) to extend the buffer time.
