SSR-40DA Solid State Relay Kit DC to AC 3-32V to 24-380V 40A with Heat Sink/Case/Thermal Paste

SSR-40DA Solid State Relay Kit DC to AC 3-32V to 24-380V 40A with Heat Sink/Case/Thermal Paste

Precise Voltage Control - 3-32V DC input, 24-380V AC output, 40A max load. Ideal for PID controllers & industrial equipment The set includes 2 SSR-40DA relays, 2 aluminum heat sinks, 2 transparent protective covers, 4 small packets of thermal paste, and 4 screws. Safety Protection - Epoxy encapsulation + transparent cases prevent dust/shorts. ≥2.5KV isolation, silent operation Easy Installation - M4 screw holes for DIN rail/panel mount. Compatible with thermostats/heaters/motors Stable Performance - Zero-cross trigger minimizes EMI. Supports resistive/capacitive loads (-30℃~80℃) Dual relays for redundant operation. ±1.5% phase control accuracy, ≤10ms response.Anodized heatsinks (thermal resistance ≤1.2℃/W) + paste (≥2.5W/mK) ensure continuous cooling.Transparent PC case with snap-fit design fits SSR-40DA/40DA-H/25DA in 3 seconds.Input LED for status monitoring. Built-in RC snubber suppresses voltage spikes.4x 304 stainless screws resist corrosion, perfect for humid/high-temp workshops
