SSR-DD 60 Relay

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

The SSR-60 DD is a high-power DC to DC solid state relay (SSR) designed for switching resistive or inductive DC loads up to 60A. With no moving parts, it offers fast switching, silent operation, and long life, making it ideal for industrial automation, battery chargers, heating systems, and motor control applications.

✅ Specifications:

• Control Voltage: 3 – 32V DC

• Load Voltage: 5 – 60V DC

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

• Switching Type: DC to DC (MOSFET based)

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

• Turn-On/Turn-Off Time: ≤ 0.1ms

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

• Status Indicator: LED (Red = On)

• Housing: Aluminum / Plastic base for heatsink mounting

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

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

📦 Features:
✔️ Silent and fast solid state switching
✔️ 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:
✔️ DC motor speed control (PWM compatible)
✔️ Battery charger switching
✔️ LED and lighting control
✔️ Industrial heating and temperature control
✔️ Electroplating and anodizing power supplies
✔️ DC power supply switching
✔️ Solar charge controllers
✔️ CNC and automation equipment

⚠️ Important Notes:

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

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

• Polarity matters: Output is polarized (Output + and Output -). Connect correct polarity.

• Low-side switching: Typical configuration is switching the negative side of the load.
