The DC-to-DC 25A Solid State Relay is a compact, silent, and efficient switching solution designed for high-speed DC load control. Unlike mechanical relays, this SSR contains no moving parts, providing reliable performance, fast response times, and long operational life. Perfect for automation systems, battery-powered circuits, motor controls, LED lighting, and solar-powered electronics.
- Rated Current: 25 Amps continuous DC load switching
- Input (Control) Voltage: 3–32 VDC – compatible with most PLCs, microcontrollers, or logic boards
- Output (Load) Voltage: 5–220 VDC (varies by model)
- Trigger Current: Low current activation, suitable for low-power control sources
- Fast Switching: Typically <1 millisecond response time
- Fully Solid-State Design: No noise, no arc, no mechanical wear
- LED Indicator: Shows control signal status clearly
- Opto-Isolated Input: Ensures strong separation between control and load side for safety
- Compact Size: Space-saving, ideal for modular control panels
- Reverse Polarity Protection: (varies by model) protects against wiring errors
- Heat Dissipation: The mounting surface acts as a passive heat sink; active cooling recommended for higher currents
