Feature: 1. INTELLIGENT CHIP: The relay operates stably and has strong overcurrent. The isolation between the control terminal and the load terminal is realized by an isolator. 2. RED COPPER BOTTOM PLATE: The relay adopts red copper base plate, the surface is flat, the heat dissipation is fast, and it has the function of overheating protection. 3. SAFE USAGE: There is no need for internal mechanical contact when the relay is running, no sparks are generated, low noise, and it is safer and more secure to use. 4. ABS MATERIAL: The relay is made of ABS material specially used for industrial electric heating, which is environmentally friendly and safe. 5. WIDE APPLICATION: Relays can be widely used in aerospace, ships, household appliances, machine tools, communications, automobiles, mining, automation control and other fields. Specification: Item Type: Industrial Solid State Relay Material: ABS, red copper Model: H3400A Load Current: 400A On Off Time: ≤10ms Input Voltage: 3-32V DC Output Voltage: 24-480V AC Ambient Temperature: -30℃-70℃ Off State Leakage Current: ≤5mA Placement Method: Bolt fixing Work Indication: LED Control Mode: DC to AC. Package List: 1 x Industrial Solid State Relay2 x Power Cable Note: How to calculate current:Equipment power ÷ voltage = currentCurrent ÷ coefficient = select solid state currentThe factor depends on the load type of the equipment you are bringingResistive load: 60%Inductive load: 30%For example: a motor rated at 1500W, the motor is an inductive load, then the formula: 1500W÷220V=6.8; 6.8÷0.3=22A, we need to choose to buy a 25A solid state relay.
