SSR-60 DA Relay

🔹 SSR-60 DA Solid State Relay – DC to AC, 60A, 3-32V DC Control

The SSR-60 DA is a high-power DC to AC solid state relay (SSR) designed for switching AC loads up to 60A using a low-voltage DC control signal. With no moving parts, it offers fast switching, silent operation, and long life, making it ideal for industrial automation, heating systems, lighting control, and motor applications.

✅ Specifications:

• Control Voltage: 3 – 32V DC

• Load Voltage: 24 – 380V AC (typical)

• Load Current: Max 60A (with proper heatsink)

• Switching Type: DC to AC (Triac based)

• Control Current: 5mA – 20mA (typical)

• Turn-On/Turn-Off Time: ≤ 10ms (zero-crossing switching)

• Isolation Voltage: ≥ 2500V RMS (input to output)

• Status Indicator: LED (Red = On)

• Housing: Aluminum / Plastic base for heatsink mounting

• Terminals: Screw type (Input +/-, Output Load)

• Dimensions: ~45mm x 58mm x 25mm (typical)

📦 Features:
✔️ Silent and fast solid state switching
✔️ Zero-crossing switching (reduces electrical noise)
✔️ No contact wear – long operational life
✔️ 3-32V DC control logic – compatible with microcontrollers (Arduino, ESP32, etc.)
✔️ Built-in LED status indicator
✔️ High isolation voltage for safety
✔️ Optically isolated input/output

📦 Applications:
✔️ Industrial heating and temperature control
✔️ AC motor control (fans, pumps)
✔️ Lighting control (incandescent, resistive)
✔️ Home automation and smart switching
✔️ CNC and automation equipment
✔️ Battery charger AC switching
✔️ HVAC systems

⚠️ Important Notes:

• Heatsink required: At 60A, a suitable heatsink and thermal paste are mandatory to prevent overheating.

• AC only: This is a DC-to-AC SSR – do not use for DC loads.

• Zero-crossing: The relay switches ON only at AC zero-crossing, which reduces EMI but may not work for phase-angle control.

• Minimum load current: Some SSRs require a minimum load current (typically 50-100mA) for proper operation.
