The 75A DC-to-AC Solid State Relay (SSR) is a robust and reliable solution for switching high-power AC loads using low-voltage DC control signals. Engineered for heavy-duty use in industrial automation, heating systems, motor control, and lighting, this SSR delivers arc-free, silent operation with high-speed switching and long life. Ideal for environments where durability, safety, and low maintenance are essential.
- High Load Current Capacity:
Handles up to 75 Amps of continuous AC—great for medium to heavy industrial use. - Low-Voltage Control:
Accepts 3–32 VDC input, compatible with PLCs, Arduino, Raspberry Pi, or other microcontrollers. - AC Load Switching:
Controls 24–480 VAC on the output side for standard single-phase or light 3-phase systems. - Zero-Crossing Trigger Technology:
Reduces electrical noise and stress on components during switching. - Fast Switching Time:
Typically <10 milliseconds for on/off cycles. - LED Status Indicator:
Built-in LED confirms signal status at a glance for easy diagnostics. - No Moving Parts:
100% solid-state = silent, vibration-resistant, and no contact wear. - Built-In Snubber Circuit:
Absorbs voltage spikes, ensuring safe switching of inductive loads. - Panel Mount Design:
Heavy-duty aluminum base for easy mounting and excellent heat dissipation.Â
