Specification: Item Type: Solid State Relay Material: Plastic + Metal Color: Shown As Pictures Input Current: 6-12mA Output Current: 40A On/Off Time: ≤ 10ms Off-state Leakage Current: ≤ 2mA Application: Military/Aerospace, Lighting Electronics, Medical Electronics, New Energy Package Weight: Approx. 120g Package List: 1 * 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 to the quality inspection of the relay and radiator for better heat dissipation. When the temperature of the radiator surface is close to 60°C, forced air should be used. 2. The actual use value of the output current of the solid state relay should be 1/3 of the rated value. For example, if 40A is used within 12A, it will be easily damaged if it exceeds 40A.
