Specification: Item Type: Solid State Relay Material: Plastic + Metal Color: As shown in pictures Input Voltage: 3-32VDC Input Current: 6-12mA Output Voltage: 5-220VDC Output Current: 40A On-state Voltage Drop: 1V On/Off Time: 10ms Off-state Leakage Current: 2mA Isolation Voltage: 1500VAC Application: Military/Aerospace, Lighting Electronics, Medical Electronics, New Energy Package Weight: Approx. 120g Package List: 1 x Solid State Relay Note: 1. The radiator is used to assist heat dissipation. Solid-state relays with a working current of more than 10A must be installed with a radiator. Thermal grease can be added between the relay and radiator for better heat dissipation. When the surface temperature of the radiator approaches 60°C, forced air cooling should be used. 2. The actual usage value of the output current of the solid state relay should be 1/3 of the rated value. For example, a 40A relay should be used within 12A; it may be easily damaged if the current exceeds the rated value.
