SSR-25DD Solid State Relays (Pack of 2) - DC 3–32V Input, DC 5–200V Output, 25A Single Phase for Industrial Automation & Temperature Control

Industrial-Grade Solid State Relay Solution The SSR-25DD solid state relay delivers silent, maintenance-free switching for DC automation systems. Engineered to replace electromechanical relays, this optically isolated device responds instantly to control signals without physical contacts, ensuring consistent performance in demanding applications.  Technical Specifications  Input Control Range: 3–32V DC  Output Load Capacity: 5–200V DC / 25A  Insulation Resistance: 500MΩ at 500VDC  Off-State Leakage: ≤5mA  Operating Temperature: -30°C to +70°C  Termination: Screw terminals (copper alloy)  Key Applications  Temperature regulation in ovens, furnaces, and climate control systems  Motor control for CNC equipment and conveyor systems  Remote switching in security/access control panels  Power management for DC lighting arrays and battery charging stations  Installation & Compliance  Zero-cross triggering prevents voltage spikes during switching cycles.  Mount vertically on DIN rails or flat surfaces using integrated heatsink (thermal paste recommended for >15A loads).  Always disconnect power during installation and verify voltage compatibility.

• Non-Mechanical DC Switching: Electronic switching without moving parts enables rapid ON/OFF transitions (≤10ms) and eliminates contact wear, sparking, or noise during operation.
• Precision Voltage Handling: Supports DC 3–32V input control signals and switches DC 5–200V output loads up to 25A, ideal for CNC machinery, HVAC systems, and industrial controllers.
• Enhanced Safety Isolation: Provides 500MΩ/500VDC insulation resistance between control and load circuits, protecting low-voltage components from high-voltage surges.
• Rugged Environmental Tolerance: Metal heat-dissipation plate and sealed construction ensure reliable operation in dusty, humid, or corrosive environments (-30°C to +70°C).
• Dual-Pack Value: Includes two relays for critical redundancy or multi-circuit installations, backed by lifetime warranty against manufacturing defects.
