Single‑Phase Solid State Relay SSR‑40DA (40 A)

Switch high-current AC loads safely and efficiently with the SSR-40DA 40A Solid State Relay. Designed for automation, industrial, and DIY projects, this relay allows a low-voltage DC signal to control single-phase AC devices quickly, quietly, and reliably.

Key Features:

• Input Control Voltage: 3 – 32 V DC – compatible with microcontrollers, PLCs, and logic-level circuits

• Output Load Voltage: 24 – 380 V AC – ideal for single-phase AC devices

• Rated Load Current: 40 A – capable of handling high-current AC loads with proper heat dissipation

• Zero-Cross Switching: Reduces electrical noise and ensures smooth operation

• LED Indicator: Shows relay status at a glance

• Durable Design: No mechanical parts, ensuring long service life

Applications:

• Temperature controllers and PID systems

• Electric heaters, ovens, and motors

• Industrial automation and process control

• Lighting and signage

• HVAC systems

Note: For high-current applications near the 40 A rating, a heatsink is recommended to prevent overheating and ensure long-term reliability.
