Feature 1 NON CONTACT AND LOW NOISE: No sparks are safe and secure. Using internal working method, no need for internal mechanical contact to work, no sparks, low noise, and more assured use 2 GOOD ISOLATION: Stable operation of smart chip bring strong overcurrent, isolation between control terminal and load terminal with isolator 3 OVERHEATING PROTECTION: Fast heat dissipation and stable operation, enhanced type adopts excellent copper base plate, with smooth surface, fast heat dissipation, and prevent overheating 4 SAFE MATERIAL: Adopt industrial grade materials, environmentally friendly, safe, reliable and durable. Special for electric heating, strong interference resistant, small size, light weight, many varieties, complete specifications 5 WIDE APPLICATION: Can be widely used in aerospace, ships, household appliances, machine tools, communications, automobiles, mining, automation control and other fieldsItem Type: Solid State RelayModel: H3250AMaterial: ABS, copperLoad Current: 250AOn Off Time: 10msInput Voltage: 3-32V DCOutput Voltage: 24-480V ACAmbient Temperature: -30~70Off State Current Leakage: 5mAPlacement Method: Bolt fixingWork Indication: LEDControl Mode: DC to AC Package List1 x Solid State Relay2 x Power CordNoteThe 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 relay and radiator for better heat dissipation. When the temperature of the radiator surface is close to 60C, forced air cooling should be used. The above must be strengthened by air cooling or water cooling.
