Product Description

The SDDR Series is a 20A DIN Rail Redundancy Module designed to enhance system reliability by providing 1+1 and N+1 power redundancy solutions. It integrates advanced MOSFET technology for efficient energy conversion, low heat generation, and minimal voltage drop. Ideal for industrial automation, semiconductor equipment, and electromechanical systems requiring robust power backup.

Key Features

• Redundancy Support:

  • 1+1 hot-swappable redundancy for seamless failover.
  • Scalable N+1 configuration for multi-PSU systems.

• Universal Input Voltage:

  • Supports 12V/24V/48V DC input (adjustable via model suffix).

• Efficient Design:

  • MOSFET Switching reduces power loss and input-to-output voltage drop.
  • Free Air Convection Cooling ensures operation without fans.

• Robust Performance:

  • -40°C to +80°C ultra-wide operating temperature range
  • Slim 32mm width for space-constrained applications.

• Monitoring & Safety:

  • Built-in 2-Channel DC OK Relay Contacts for real-time output status feedback.
  • Compliant with IEC62368-1, UL62368-1, and EAC TP TC004 safety standards.
