SITOP smart

高性能标准电源适用于单相和三相网络

SITOP smart 高性能标准电源,适合带有 24V 或 12V 电子元件的自动化机器和系统。它不仅外形紧凑,还具有出色的过载特性。其容量可达额定电流的 1.5 倍并持续 5 s/min,从而能够可靠连接需要较高功率的用电设备。同时,这种紧凑型电源单元的额定容量可达 120%,在同类产品中最为可靠。

为进一步提高可用性,SITOP smart 电源单元还可与直流 UPS、冗余和选择性模块结合使用。

New: SITOP PSU300S 24 V/5 A and 10 A


The standard product line SITOP smart has been extended with a 5 A power supply and a 10 A version for smaller power demands on 3-phase systems. The new SITOP PSU300S with a 5 A rated output current and a width of only 50 mm can be mounted on a DIN rail. The width of the 10 A variant has been reduced by 20 mm to 70 mm.

Their high efficiency of up to 91% for both power supplies generate only a small amount of heat in the control cabinet. The devices have a 3-phase input range of 340 VAC to 550 VAC, that reliably ensures an output of 24 volts, even if there are large fluctuations in the supply voltage. The extra power of 1.5 times the rated voltage for five seconds makes it possible to carry loads with high power requirements.

The international certifications such as ATEX, IECEx, and GL as well as an ambient temperature range from -25 to 70 °C mean they can be used in diverse industries around the world.
