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 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 temperaturesand 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.
