Johnston Technologies offers four different categories of rack Power Distribution Units (rPDUs). Each product offers a variety of advantages for individual IT environments. These advantages allow our customers to choose which solution fits their need the best.
Each rPDU category can generally be relayed over for each brand. Some brands, however, offer different technologies. For example, Geist offers scalable monitoring features that are hot-swappable. For more information about Geist Upgradeable power strips, read our blog.
