The DRM40 series of 20 to 40A DIN rail mount redundancy modules can be used in N+1 redundancy applications or to parallel two power supplies for additional power. The DRM40 has a current balancing LED indicator which is illuminated when both power supplies have been adjusted to deliver the same current. Two isolated alarm signals indicate the output voltage status of each power supply. Internally the DRM40 has a low 200mV voltage drop.
