DIN rail power modules deliver N+1 redundancy

DIN rail power
RS Components is now stocking the DRM40 and DRM40B DIN rail-mount redundancy power modules from TDK-Lambda for automation and general-purpose industrial applications.

The units offer 20 to 40A current handling capability and can be used in N+1 redundancy systems and applications; alternatively, two supplies can be placed in parallel for additional power.
A key feature of the higher-end DRM40 unit is a current-balancing LED indicator, which turns on when two power supplies have been adjusted to deliver the same current, thereby making it easier to ensure load sharing. In addition, two isolated alarm signals indicate the output voltage status of each power supply, making it simple to enable remote fault monitoring. However, the lower cost unit DRM40B is also available for applications not demanding these advanced features. Designed to take up less space on the DIN rail, the DRM40 series comes in a highly compact unit with dimensions of only 35x125x124mm, with an operating temperature range of –40 to +70ºC. Shipping now from RS in the EMEA and Asia Pacific regions, the series also meets the IEC/EN/UL60950-1, IEC/EN/UL62368-1 and UL508 safety standards for a range of industries and applications.
