The 40A DC-to-AC Solid State Relay (SSR) is a high-performance switching device designed to control AC loads using a DC control signal. With no moving parts, it ensures silent operation, faster switching, and longer life compared to traditional mechanical relays. Perfect for industrial automation, HVAC systems, heaters, motor control, and lighting applications where durability and reliability are critical.
- Current Rating: 40 Amps (continuous load capacity)
- Control Voltage (Input): Typically 3–32 VDC
- Load Voltage (Output): 24–480 VAC (varies by model)
- Trigger Current: Low trigger requirement (~7.5 mA typical)
- Zero-Crossing Function: Built-in zero-crossing detection to reduce electrical noise and voltage spikes
- LED Indicator: Displays control signal status for easier troubleshooting
- Fast Response Time: Switching speed in milliseconds – ideal for automation systems
- No Mechanical Parts: Solid-state design means no wear, no sparks, and no noise
- Built-In Snubber Circuit: Protects against high voltage transients
- Mounting: Panel mount with heat sink compatibility for better heat dissipation
- Insulation Resistance: High isolation between control and load sides for safety
