SSR-DA Single Phase Solid State Relay, DC to AC Control, 10A–100A
SSR-DA Series Single Phase Solid State Relay is a DC control AC output solid state relay designed for reliable switching of AC loads. It accepts a 3–32VDC control signal and switches 24–380VAC load voltage, making it suitable for heating equipment, lighting systems, blowers, packaging machines and industrial automation control systems. The SSR-DA series is available in 10A, 25A, 30A, 40A, 50A, 60A, 75A, 80A and 100A current ratings.
- DC control AC output solid state relay
- 3–32VDC input control voltage
- 24–380VAC load voltage range
- Zero-cross trigger for stable switching
- LED status indicator
- No mechanical contacts, silent operation
- Compact screw-mounted structure
- Available from 10A to 100A
- Suitable for heating, lighting and automation systems
- Use a properly sized heat sink and thermal compound. Required cooling depends on the actual load current, ambient temperature, duty cycle, enclosure ventilation and heat-sink thermal resistance. Apply appropriate derating. Forced-air cooling may be required for high-current or continuous-duty operation.
