RS Components adds DIN-rail redundancy power modules

TDK-Lambda’s latest series of DIN-rail mounted redundancy power modules are now available from RS Components.

The compact modules are aimed at N+1 redundancy applications in industrial markets and are designed for automation and general-purpose industrial applications, says RS Components.

The DRM40 and DRM40B power modules 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.

The DRM40 unit has a current-balancing LED indicator, which turns on when two power supplies have been adjusted to deliver the same current. This makes it easier to ensure load sharing. Two isolated alarm signals indicate the output voltage status of each power supply, for remote fault monitoring. The DRM40B does not have these features, which is reflected in the lower cost for this model.

Designed to take up less space on the DIN rail, the DRM40 series measures just 35 x 125 x 124mm. Operating temperature range is –40 to +70 degrees C, key electrical characteristics include an internal voltage drop of just 200mV at 40A, a wide input voltage range of 10 to 30V and maximum input current of 20A on each of the unit’s two inputs, plus a peak input capability of 2 x 30A for four seconds.

Shipping now from RS in the EMEA and Asia Pacific regions, the DRM40 series also meets the IEC/EN/UL60950-1, IEC/EN/UL62368-1 and UL508 safety standards for a range of industries and applications.

RS Components is a trading brand of Electrocomponents. It offers over 500,000 industrial and electronic products, sourced from over 2,500 leading suppliers and has operations in 32 countries, shipping more than 50,000 parcels a day.

The distributor supports customers across the product life cycle, with innovation and technical support at the design phase, improving time to market and productivity at the build phase, or reducing purchasing costs and optimising inventory in the maintenance phase.
