Widely used in many automatic control systems Specification: This is a 3 phase solid state relay LSR1-3-325AA .Model: LSR1-3-325AA Input voltage: 90-250AC .Output voltage: 24-440V AC.Output current: 25A Total Size: 10.5 x 10 x 12cm/ 4 x 3.9 x 4.7inch (L*W*H) Package Content:1 x Solid State Relay LSR1-3-325AA 1 x HeatSink Matters Needing Attention: 1. The current on the product is the maximum load current, not the rated current. 2. On the basis of the difference in the load character, you should keep the difference on the level of the current when you choose the product. (When the load is resistive, the load current should be 1/2-1/3 times the max load current . When the load is inductive or capacitive, like a motor, or transformer, the load current should be 1/4-1/6 times of max load current.) 3. When Installation, solid state plate and radiator with smeared thermal conductivity silicone grease 4. ≥10A With radiator, ≥20A with radiator and fan strong cold. 5. The thermal compound has been applied evenly between the heatsink and the SSR, MAYBE IT LOOKS LIKE Spots AND IS NOT CLEAN MUCH, but it is for better heat dissipation, please note.
