DRDN20-24: DIN rail redundancy module - 24Vdc

The DRDN20 series is a 20A redundancy module that can be used with a power supply to improve the overall operational reliability of the system. The main features of the product include: selectable input voltage of 12V, 24V or 48V, support for N+1 and 1+1 redundancy systems, two DC input terminals integrated on the rail and a single output. The implemented MOSFET technology reduces heat dissipation and the voltage difference between input and output; it also includes 2 integrated DC OK relay contacts for monitoring the output status, an ultra-wide operating temperature range from -40 to +80 °C and a compact width (32 mm).
