PULS Dual Diode Redundancy Module for Use with Y Series YR Series, DC 12 V to 48 V, 20 A Input/Output YR2.DIODE

The PULS YR2.DIODE is a dual diode redundancy module specifically engineered for building reliable 1+1 and N+1 redundant power supply systems. Compatible with the PULS Y and YR Series power supplies, it accepts two DC inputs rated at 10 A each, and provides one DC output capable of carrying nominal currents up to 20 A. This makes it a robust solution for enhancing power supply reliability in industrial and commercial applications.

Designed to operate with DC input voltages from 12 V to 48 V (±25%), the module maintains a notably low voltage drop of only 0.85 V between input and output even under full load. The device sustains its rated current continuously across a wide ambient temperature range from -40 °C to 60 °C, ensuring dependable operation in harsh environmental conditions.

The YR2.DIODE features quick connect spring-clamp terminals for simplified installation and maintenance. Its input channels include reverse polarity protection to safeguard connected equipment. With a compact form factor measuring 32 mm wide, 124 mm high, and 102 mm deep, and a lightweight 290 g chassis, the module is well-suited for DIN rail mounting in control cabinets.

Compliant with recognized international standards including IEC, UL, EN, and SELV, the module meets stringent safety and performance requirements. It is commonly applied to isolate sensitive load circuits and integrate with power supplies equipped with DC-OK signaling, thereby preventing power quality distortion and avoiding controller failures in critical industrial, laboratory, HVAC, manufacturing, and commercial environments.

The module offers two 10 A input channels and a 20 A output channel to enable flexible redundant power supply configurations. Low voltage drop and extended temperature range operation ensure power efficiency and system reliability.

Quick connect terminals and reverse polarity protection simplify installation and improve safety. Compact size and lightweight design support easy integration into various electrical panels and systems. Conforms to IEC, UL, EN, and SELV standards for industrial power supply accessories.
