Key Features

1. High Load Switching Capacity (25A)

• Supports a high continuous load current of 25A, making it ideal for power-intensive applications.
• Suitable for controlling resistive, inductive, and capacitive loads efficiently.

2. Wide Input and Output Voltage Range

• Works with low voltage DC inputs (3-32V DC), making it compatible with most PLC outputs, microcontrollers, and industrial control systems.
• Can switch AC loads between 24V and 300V, providing flexibility across multiple industrial applications.

3. Zero Voltage Switching (ZVS) for Noise Reduction

• ZVS ensures that switching occurs when the AC voltage crosses zero, reducing electromagnetic interference (EMI) and preventing power surges.
• This feature increases the lifespan of connected loads, such as heating elements and industrial equipment.

4. Solid-State Durability – No Moving Parts

• Unlike mechanical relays, SSR technology eliminates moving parts, making it resistant to shock, vibration, and wear.
• Provides fast switching speeds for improved system response.

5. High Electrical Isolation for System Protection

• Electrically isolates the input from the output, preventing voltage spikes or fluctuations from damaging the control system.
• Ensures safe operation in industrial environments.

6. Panel Mounting with Heat Sink Requirement

• Designed for easy panel mounting, making integration into control panels simple.
• Requires a heat sink to dissipate excess heat, ensuring efficient thermal management and preventing overheating.
