The PULS Diode Redundancy Module Series enables parallel operation of two power supplies in a redundant configuration, ensuring continuous system operation even if one supply fails. By using diode decoupling technology, these modules prevent reverse current flow between paralleled supplies and provide automatic load sharing — a critical requirement in high-availability industrial control systems, safety systems, and any application where unexpected downtime is unacceptable.

The diode-based approach is proven, reliable, and requires no active control electronics. Units are available from 2A (YR2, YRM2) for small-scale applications up to 20A (PIRD20.241) for larger systems. The MLY variants are specifically matched to MiniLine power supplies for an integrated and space-efficient redundant power solution.
