Residual Current Monitoring (RCM)

In many jurisdictions, such as the German, datacenters and serverrooms must check quarterly or annually for leakage current from neutral-to-ground (residual current monitoring). Our rack PDUs are available with an (optional) residual current monitoring (RCM) feature that automates this task completely, without having to schedule any maintenance windows. We decided to use Bender technology in our PDUs with RCM as they measure AC and DC leakage current in the most reliable and accurate way. Using residual current monitoring allows changes in the level of insulation of a power supply to be detected at an early stage, before protective devices are tripped by a residual current that puts people at risk and involves the risk of fire.
