Residual current monitoring (RCM) PDU

In many jurisdictions such as the German data centers and server rooms must be checked quarterly or annually for leakage from neutral to earth (fault current monitoring). Our Rack PDUs are available with the capability of (optional) residual current monitoring (RCM), which fully automates this task without having to schedule maintenance windows. With fault current monitoring, changes in the degree of isolation of a power supply can be detected early on, before protective devices are triggered by a fault current that puts people in danger and creates a fire hazard. We chose to use Bender technology in our PDUs with fault current monitoring because they measure AC and DC leakage in the most reliable and accurate way. With fault current monitoring, changes in the degree of isolation of a power supply can be detected early on, before protective devices are triggered by a fault current that puts people in danger and creates a fire hazard.
